AIM:To observe the imaging features of color Doppler ultrasound(CDU)and computed tomography(CT)or computed tomography dacryocystography(CT-DCG)in different types of lacrimal sac space-occupying lesions(SOLs).METHODS:This retrospective case series study included 21 patients with lacrimal sac SOLs who underwent lacrimal sac surgery between January 2018 and March 2022.The imaging features of CDU and CT or CT-DCG in these patients were extracted from the examination cloud system.The images were observed and analyzed.RESULTS:The detection rate of lacrimal SOLs between CDU(21/21,100%)and CT or CT-DCG(20/21,95.2%)had no statistically significant difference(P=1.0).CDU could detect the blood flow signals in all SOLs except mucocele and mucopeptide concretion.Among them,polyps had characteristic imaging changes on CDU and CT-DCG.The mucoceles and mucopeptide concretions had characteristic imaging changes on CDU,which could provide more information for differential diagnosis.CONCLUSION:The morphology and internal blood flow signals of lacrimal sac SOLs can be observed using CDU.CT or CT-DCG has advantages in observing structural damage around the lacrimal sac mass.Therefore,CDU may be used as a routine examination to exclude lacrimal sac SOLs before dacryocystorhinostomy in the absence of preoperative CT or CT-DCG. 展开更多

AIM: To study the portal hemodynamics and their relationship with the size of esophageal varices seen at endoscopy and to evaluate whether these Doppler ultrasound parameters might predict variceal bleeding in patients with liver cirrhosis and portal hypertension. METHODS: One hundred and twenty cirrhotic patients with esophageal varices but without any previous bleeding were enrolled in the prospective study. During a 2-year observation period, 52 patients who had at least one episode of acute esophageal variceal hemorrhage constituted the bleeding group, and the remaining 68 patients without any previous hemorrhage constituted the non-bleeding group. All patients underwent endoscopy before or after color Doppler-ultrasonic examination, and images were interpreted independently by two endoscopists. The control group consisted of 30 healthy subjects, matched to the patient group in age and gender. Measurements of diameter, flow direction and flow velocity in the left gastric vein (LGV) and the portal vein (PV) were done in all patients and controls using color Doppler unit. After baseline measurements, 30 min after oral administration of 75 g glucose in 225 mL, changes of the diameter, flow velocity and direction in the PV and LGV were examined in 60 patients with esophageal varices and 15 healthy controls. RESULTS: The PV and LGV were detected successfully in 115 (96%) and 105 (88%) of 120 cirrhotic patients, respectively, and in 27 (90%) and 21 (70%) of 30 healthy controls, respectively. Among the 120 cirrhotic patients, 37 had F1, 59 had F2, and 24 had F3 grade varices. Compared with the healthy controls, cirrhotic group had a significantly lower velocity in the PV, a significantly greater diameter of the PV and LGV, and a higher velocity in the LGV. In the cirrhotic group, no difference in portal flow velocity and diameter were observed between patients with or without esophageal variceal bleeding (EVB). However, the diameter and blood flow velocity of the LGV were significantly higher for EVB (+) group compared with EVB (-) group (P〈0.01). Diameter of the LGV increased with enlarged size of varices. There were differences between F1 and F2, F1 and F3 varices, but no differences between F2 and F3 varices (P = 0.125). However, variceal bleeding was more frequent in patients with a diameter of LGV 〉6 mm. The flow velocity in the LGV of healthy controls was 8.70+1.91 cm/s (n = 21). In patients with liver cirrhosis, it was 10.3+2.1 cm/s (n = 12) when the flow was hepatopetal and 13.5+2.3 cm/s (n = 87) when it was hepatofugal. As the size of varices enlarged, hepatofugal flow velocity increased (P〈0.01) and was significantly different between patients with F1 and F2 varices and between patients with F2 and F3 varices. Variceal bleeding was more frequent in patients with a hepatofugal flow velocity 〉15 cm/s (32 of 52 patients, 61.5%). Within the bleeding group, the mean LGV blood flow velocity was 16.6+2.62 cm/s. No correlation was observed between the portal blood flow velocity and EVB. In all healthy controls, the flow direction in the LGV was hepatopetal, toward the PV. In patients with F1 varices, flow direction was hepatopetal in 10 patients, to-and-fro state in 3 patients, and hepatofugal in the remaining 18. The flow was hepatofugal in 91% patients with F2 and all F3 varices. Changes in diameter of the PV and LGV were not significant before and after ingestion of glucose (PV: 1.41+1.5 cm before and 1.46+1.6 cm after; LGV: 0.57+1.7 cm before and 0.60+1.5 cm after). Flow direction in the LGV was hepatopetal and to-and-fro in 16 patients and hepatofugal in 44 patients before ingestion of glucose. Flow direction changed to hepatofugal in 9 of 16 patients with hepatopetal and to-and-fro blood flow after ingestion of glucose. In 44 patients with hepatofugal blood flow in the LGV, a significant increase in hepatofugal flow velocity was observed in 38 of 44 patients (86%) with esophageal varices. There was a relationship between the percentage changes in flow velocity and the size of varices. Patients who responded excessively to food ingestion might have a high risk for bleeding. The changes of blood flow velocity in the LGV were greater than those in the PV (LGV: 28.3+26.1%, PV: 7.2+13.2%, P〈0.01), whereas no significant changes in the LGV occurred before and after ingestion of glucose in the control subjects. CONCLUSION: Hemodynamics of the PV is unrelated to the degree of endoscopic abnormalities in patients with liver cirrhosis. The most important combinations are endoscopic findings followed by the LGV hemodynamics. Duplex-Doppler ultrasonography has no value in the identification of patients with cirrhosis at risk of variceal bleeding. Hemodynamics of the LGV appears to be superior to those of the PV in predicting bleeding. 展开更多

Objective We investigated the efficacy and safety of 1064 nm Nd: YAG laser, intense pulsed light (IPL), and lauromacrogol injection in the treatment of hemangioma, in order to evaluate the value of color Doppler ultrasound guidance in choosing the optimal treatment modality. Methods Infantile patients who were clinical diagnosed as hemangiomas were randomly divided into group A, who had color Doppler ultrasound examinations before the treatment, and group B who had the treatment without ultrasound evaluation. Patients in the group A were assigned into subgroups according to the depth of lesion by sonography: group A-1 for those who had a lesion depth 〈1.2 mm, and took intense pulsed light therapy; group A-2 for those who had a lesion depth ≥1.2mm and 〈 3 mm, and took long pulse 1064 nm Nd:YAG laser therapy; group A-3 for those who had a lesion depth ≥3mm and 〈5 mm, and were treated by IPL combined with long pulse 1064 nm Nd:YAG laser treatment; Group A-4 for those who had a lesion depth ≥5 mm, and took lauromacrogol injection therapy. Patients in the group B took long pulse 1064 nm Nd:YAG laser treatment without preoperative ultrasound evaluation. The efficacy and adverse reactions of the treatments between the groups were evaluated and compared statistically. Results Totally 113 patients with 128 skin lesions were enrolled in this study, 85 in the group A (mean age 6.8±7.9 months) and 28 in the group B (mean age 6.9±9.9 months). The mean depth of hemangioma was 3.3±1.1 mm in the group A, ranging from 0.5-7.8 mm, with 0.8±0.4 mm, 2.2±0.4 mm, 4.2±0.6 mm and 6.2±0.7 mm in group A1, A2, A3 and A4, respectively. The cure rates and effective rates in the group A were significantly higher than those in the group B (cure rates: 64.5% vs 56.3%, U=3.378, P=0.045; effective rates: 89.5% vs 78.1%, U=4.163, P=0.041). The adverse effect rates of the group A (vesicle 20.0%, pigmentation 46.9%, scarring 17.7%) were lower than those of the group B (vesicle 21.9%, pigmentation 60.4%, scarring 25.0%). Incidences of pigmentation and scarring were statistically significantly different (U=3.884, P=0.034, and U=4.016, P=0.032 respectively) between the two groups. Conclusion With the guidance of color Doppler ultrasound, the efficacy and safety of long pulse 1064 nmNd:YAG laser, intense pulsed light, and lauromacrogol injection in the treatment of infantile hemangioma have better outcomes compared to laser treatment alone without preoperative ultrasound examination. 展开更多

The purpose of this study was to determine the efficacy of using an ultrasound contrast agent(levovist)to enhance the color Doppler imaging of liver neoplasms.Thirty patients with hepatic tumors were enrolled in this study.After intravenous administration of levovist,the color Doppler signals of normal hepatic vessels were enhanced.In various hepatic tumors,the different patterns of tumor vascularity were observed,which had not been demonstrated in conventional non contrast color Doppler imaging.In 11 of 16 patients with hepatocarcinoma,additional color Doppler signals were observed in the central part of the tumors.On the contrary,3 patients with metastatic liver lesions the enhanced color Doppler signals appear only at the peripheral of tumors.A typical rim like color enhancement was seen in 2 of the 3 cases.In six patients with hepatic hemangiomas contrast enhanced color Doppler imaging demonstrated the blood vessels at the margin of the neoplasms.Contrast enhanced color Doppler imaging improves the visualization of the hepatic neoplasm vascularity.This technique holds great promise for detecting small liver tumors and differentiating hepatic neoplasms. 展开更多

The value of color Doppler flow imaging (CDFI) and intravenous contrast-enhanced ultrasound (CEUS) for assessing the transplanted liver and early diagnosing complications by examining hemodynamic changes was discussed. Seventy-five patients with orthotopic liver transplantation (OLT) underwent CDFI. The following parameters were measured: peak systolic velocity (PS), resistance index (RI) and Doppler perfusion index (DPI) of the hepatic artery (HA), time average velocity (TAV) of portal vein (PV) and velocity of hepatic vein (HV) in different stages postoperation, And 11 patients of them received CEUS. Thirty healthy subjects were enrolled as controls, The results showed that: (1) In 23 patients without obvious complications, TAV of PV within 15 days post-operation was significantly higher than in controls (P〈0.05), PS and DPI of HA within 7 days postoperation were lower, but RI was higher than in controls (P〈0.05); (2) When the hepatic artery thrombosis (HAT) occurred, PS and DPI of HA were obviously decreased, but TAV of PV significantly increased like a high saw-tooth wave; (3) While rejection occurred, both TAV of PV and PS of HA were decreased with the increase in RI of HA, and the triphasic wave of HV disappeared and displayed as saw-tooth wave; (4) The incidence of biliary complications in liver transplantation was increased when DPI was reduced; (5) Seven cases of hepatic carcinoma relapse after OLT demonstrated hyperecho in the arterial phase and hypoecho in the portal and later phase on CEUS; (6) In 2 cases of HA thrombus, there was no visualized enhancement in arterial phase of CEUS, but enhancement during the portal vein and parenchymal phase. It was concluded that the hemodynamic changes of PV, HA and HV in the transplanted liver are valuable for assessing the transplanted liver and early diagnosing complications on CDFI and CEUS. 展开更多

Retrospective study was done at KAUH to determine the sonographic characteristics in predicting the malignancy of thyroid nodules. The sample was 120 patients consisting of 70 benign nodules and 50 malignant nodules. Out of 120 patients, 106 (88.3%) female and 14 (11.7%) male patients. Out of 106 female patients, 64 (91.45) had benign and 42 had malignant thyroid nodules. Out of 14 (11.7) male patients, 6 had benign and 8 had malignant thyroid nodules. The youngest patient in our study was 31 years and the oldest patient was 76 years. The common range of patients age was ≥ 60 years and consisting of twenty (28.6%) benign thyroid nodules and fourteen (28%) malignant thyroid nodules. The majority of patients’ age group with malignant thyroid nodules were between 50 - 60 years and consisting of twenty (40%) malignant nodules. In our study, according to the result of gray scale and color Doppler ultrasonography, hypo-echogenicity, solid echo structure, micro-calcification and intra-nodular vascularity were the significant characteristics of malignancy in nodules with sensitivity (72%, 74%, 48% and 88% respectively), specificity (66%, 63%, 94% and 69% respectively), PPV (60%, 59%, 86% and 67% respectively) and NPV (77%, 77%, 72% and 89% respectively). 展开更多

Objective To evaluate endometrial and subendometrial blood flows measured by vaginal color Doppler ultrasound as a predicator of endometrial receptivity in women undergoing IVF treatment. Methods A total of 119 infertile patients undergoing the first IVF/ICSI-ET cycle were recruited. Three groups were divided according to a color Doppler ultrasound examination performed on the day of hCG injection. Group A, endometrial and subendometrial blood flows were 2 branches and below; group B, endometrial and subendometrial blood flows were between 3 and 4 branches; group C, endometrial and subendometrial blood flows were 5 branches and above. Patients were transferred 1-3 embryos each. Demographic data, ovarian responses, endometrial thickness, PI, RI, development of embryo and IVF result among groups were compared. Results Demographic data, ovarian responses, endometrial thickness, PI, RI and development of embryo among groups have no significant difference. The pregnancy rate of group A was significantly lower than that of group B (P〈0.05) and group C (P〈0.01). The implantation rate of group A was significantly lower than than of group C (P〈0.01). There was no significant difference of the rate of pregnancy and implantation between group B and group C (P〉0.05). Conclusion Endometrial and subendometrial blood flows measured by vaginal color Doppler ultrasound is a good predicator of pregnancy during IVF treatment. A good endometrial and subendometrial blood flows is benefit for the result of IVF. 展开更多

Objective: To study the diagnostic value of color doppler ultrasound in children with thyroid nodules and thyroid cancer. Methods: A total of sixty children with thyroid nodules treated in our hospital from March 2017 to March 2018 were selected for study. All patients underwent color Doppler ultrasound diagnosis. According to the diagnostic data, benign thyroid nodules and thyroid cancer were analyzed. The nodule nature was grouped into benign nodules group and malignant nodules group. The aspect ratio and boundary of the two groups were compared in blurring, calcification, blood flow signal classification, etc. Results: A total of 95 nodules were diagnosed by color doppler ultrasonography in 60 cases of thyroid nodules. 49 cases were benign nodules. There were 80 nodules, accounting for 82.11%, 11 cases of thyroid cancer, and 15 nodules. Accounted for 15.79%. Biopsy puncture pathology confirmed 77 benign nodules and 18 malignant nodules. The pathological results were gold standard. The specificity of color Doppler ultrasound was 90%, the sensitivity was 66.67%, and the accuracy of ultrasound diagnosis was 86.32%.The two nodules were statistically significant in terms of boundary, aspect ratio, calcification, echo, and resistance index (P<0.05), but the end-diastolic blood flow velocity (EDV) and peak systolic blood flow velocity ( There was no statistical difference between the PSV levels (P>0.05).Conclusion: Color Doppler ultrasound has the advantages of simple operation, high accuracy, non-invasive and painless, and reproducible detection. The high-frequency probe can clearly display changes such as minute lesions, blood flow signals, echoes, calcifications, etc., and can diagnose thyroid cancer in time. It provides a favorable basis for clinical treatment and has important clinical warning value, especially for children with thyroid examination. 展开更多

In the study, a total of 20 red-eared turtles ( half male and half female) were selected to conduct the measurement of liver size and intrahepatic blood flow of red-eared turtles by color Doppler ultrasound. The results showed that the fight hepatic lobe could be scanned through the right carotid anterior acoustic win- dow, and the left hepatic lobe could be scanned through the left carotid anterior acoustic window, but the vision would be obstructed by the air in trachea. The liver could also be scanned through the left femoral anterior acoustic window and the fight femoral anterior acoustic window when filling of bladder was good. The correla- tion regression analysis suggested that estimated values of liver showed no linear relationship with weight, the longest back curve and the widest back curve. Through the study, the normal indicators for ultrasound examination of red-eared turtle liver were established, in order to provide a reference for examination of turtle liver. 展开更多

Objective:To explore the application value of color Doppler ultrasound in the detection of hemodynamic change in patients with chronic kidney disease (CKD). Methods:A total of 720 patients with CKD who were admitted in our hospital from June, 2014 to May, 2016 were included in the study and divided into CKD2 group (n=242), CKD3 group (n=230), and CKD4 group (n=248) according to K/DOQI guideline. Meanwhile, 100 healthy volunteers were served as the control group. The renal parenchymal thickness, length, width, thickness, and hemodynamics by the two-dimensional ultrasound and color Doppler ultrasound in the four groups were observed. Results:The renal parenchymal thickness, length, width, and thickness in CKD2 group were reduced when compared with the control group, but the difference was not statistically significant (P>0.05);the above indicators in CKD3 group were significantly lower than those in the control group and CKD2 group (P<0.001);and the comparison of the above indicators between CKD4 group and other three groups was statistically significant (P<0.001). The comparison of hemodynamic parameters between CKD2 group and the control group was not statistically significant (P>0.05). The various hemodynamic parameters of Vs and Vd in CKD3 group were significantly lower than those in the control group and CKD2 group (P<0.001), while the various indicators of RI were significantly higher than those in the control group and CKD2 group (P<0.001). The various hemodynamic parameters of Vs and Vd in CKD4 group were significantly lower than those in the other three groups (P<0.001), while the various indicators of RI were significantly higher than those in the other three groups (P<0.001). Conclusions:Application of color Doppler ultrasound in detection of the hemodynamic change in patients with CKD can provide a reliable evidence for the disease diagnosis, condition monitoring, and prognosis evaluation, with an important application value. 展开更多

Objective:To study the color Doppler ultrasound parameters of asphyxial neonatal left ventricular function and the correlation with target organ damage.Methods: Normal neonates, mildly asphyxial neonates and severely asphyxial neonates born in our hospital between January 2014 and December 2015 were selected as the control group (n = 46), mild asphyxia group (n= 37) and severe asphyxia group (n = 23) respectively. On the 1st day after birth, color Doppler ultrasound was used to evaluate left ventricular function, and serum was collected to determine myocardial tissue injury, brain tissue injury and brain tissue metabolism indexes. Results: Color Doppler ultrasound parameters cardiac output (CO), ejection fraction (EF) and left ventricular fraction shortening (FS) as well as serum folate and vitamin B12 content of mild asphyxia group and severe asphyxia group were significantly lower than those of control group (P<0.05) while serum creatine kinase isoenzyme (CK-MB), troponin I (cTnI), troponin T (cTnT), S100B, neuron-specific enolase (NSE), creatine kinase BB (CK-BB), glycogen phosphorylase BB (GPBB), and homocysteine (Hcy) content were significantly higher than those of control group (P<0.05);CO, FS and EF as well as serum folate and vitamin B12 content of severe asphyxia group were significantly lower than those of mild asphyxia group (P<0.05) while serum CK-MB, cTnT, cTnI, S100B, NSE, CK-BB, GPBB and Hcy content were significantly higher than those of mild asphyxia group (P<0.05).Conclusions:Color Doppler ultrasound can accurately assess asphyxial neonatal left ventricular function damage degree and is closely related to myocardial tissue injury and brain tissue injury degree. 展开更多

Cerebral hemorrhages are fairly common in full-term neonates with no history of traumatic birth, mostly limited, and with benign evolution. We report a case of a full-term neonate from vaginal birth with caput succedaneum in the right parietal area. The neonate underwent cranial ultrasonography and color Doppler which showed extra-axial blood effusion. Color Doppler showed vessels crossing the collection area, which allowed the diagnosis of subarachnoid hematoma. 展开更多
