Diagnostic Value and Misdiagnosis Analysis of Conventional Ultrasonography Combined with Contrast-Enhanced Ultrasonography in Thyroid Nodules

Objective:To explore the diagnostic value of conventional ultrasonography combined with contrast-enhanced ultrasonography in thyroid nodules.Methods:From June 2021 to July 2022,163 patients with thyroid nodules enrolled in our hospital were selected as research subjects.After pathological diagnosis,24 cases were malignant thyroid nodules,and 139 cases were benign thyroid nodules.The diagnosis rate of malignant and benign thyroid nodules was observed and analyzed,with 95%CI.Results:Among them,the malignant and benign detection rates of routine ultrasound were 88.63%and 75.00%,respectively,and the malignant and benign detection rates of contrast-enhanced ultrasound were 81.82%and 81.25%,respectively.The malignant and benign detection rates of conventional ultrasound combined with contrast-enhanced ultrasound were 93.18%and 87.50%,respectively,and the 95%CI was greater than 0.7.Conclusion:Conventional ultrasound combined with contrast-enhanced ultrasound can help improve the diagnostic accuracy of benign and malignant thyroid nodules and reduce the misdiagnosis rate.

Application Value of Contrast-Enhanced Ultrasound in the Diagnosis of Breast Lesions

Objective:To explore the value and effect of contrast-enhanced ultrasound in the diagnosis of breast lesions.Methods:Seventy-two patients with breast lesions in Shaanxi Provincial People’s Hospital from June 2020 to December 2021 were selected as the research subjects.All 72 patients met the diagnostic criteria of breast lesions.Two patients with incomplete clinical data were excluded;hence,there were 70 patients remaining.The diagnostic results of the two examination methods and the diagnostic value of the joint examination for breast lesions were analyzed and compared.Results:The results of benign,malignant,missed,and misdiagnosed breast lesions by contrast-enhanced ultrasound were 31,32,6,and 1 cases,respectively,accounting for 44.29%,45.71%,8.57%,and 1.43%,respectively.The results of benign,malignant,missed,and misdiagnosed breast lesions by ultrasound automatic volume imaging were 21,24,17,and 8 cases,respectively,accounting for 30.00%,34.28%,24.29%,and 11.43%,respectively.There were statistical differences between the two groups for missed diagnosis and misdiagnosis,but there was no significant difference between the two groups for benign and malignant lesions.The accuracy,sensitivity,and specificity of contrast-enhanced ultrasound were 87.69%,83.62%,and 83.45%,respectively;the accuracy,sensitivity,and specificity of ultrasound automatic volume imaging were 71.39%,68.99%,and 74.69%,respectively;the accuracy,sensitivity,and specificity of contrast-enhanced ultrasound combined with ultrasound automatic volume imaging were 96.29%,92.68%,and 91.78%,respectively.Conclusion:Contrast-enhanced ultrasonography has a high clinical application value and a low inspection error rate in the diagnosis of breast lesions.It merits clinical advancement since it helps doctors diagnose and treat breast lesions more effectively.

Diagnostic Value of Serum TSH,Ultrasound,and Enhanced CT in Papillary Thyroid Carcinoma with Lymph Node Metastasis

Objective:To explore the diagnostic value of serum TSH,ultrasound,and enhanced CT in papillary thyroid carcinoma with lymph node metastasis.Methods:168 patients who underwent thyroidectomy in Shaanxi Provincial People’s Hospital from January 2020 to December 2021 were selected as the research subjects.Based on the pathological nature(benign or malignant),they were divided into two groups,with 86 patients in the control group and 82 patients in the study group.Based on whether the pathology was accompanied with lymph node metastasis,the PTC group was divided into a lymph node metastasis group and a non-lymph node metastasis group,with 51 and 31 patients in the respective groups.Retrospective analysis was conducted to observe and analyze the pathological results of the thyroid nodules’thyroid ultrasound results,neck enhanced CT results,and thyroid function test serology results.Results:Compared with the PTC group,there were significant differences in TR classification,ultrasonic lymph nodes,and enhanced CT lymph nodes,but no significant differences in the course of disease,nodule distribution,and the number of nodules between the benign nodule group and PTC group;in the comparison of lymph node metastasis using ultrasound and enhanced CT,the number of patients with ultrasound lymph nodes without abnormal metastasis in the non-metastasis group was 28,while that of the metastasis group was 21;the number of patients with abnormal metastasis in the non-metastasis group was 3,while that of the metastasis group was 30.The number of patients with a single node without metastasis and metastasis was 14 and 8,respectively,whereas the number of patients with multiple nodes without metastasis and metastasis was 17 and 43,respectively.There were statistically significant differences in the number of ultrasound lymph nodes and nodules,but no statistically significant differences in TR classification,enhanced CT lymph nodes,nodules distribution,and disease course.Conclusion:Serum TSH can be used to identify the nature(benign and malignant)of thyroid nodules,and enhanced CT is better than ultrasound when evaluating complex lesions.It can be used as a supplement to ultrasound based on clinical context.
