Imaging Characteristics and Benign/Malignant Analysis of Ground Glass Nodules in the Lungs Using 64-Slice Spiral CT

目的:探究分析64排螺旋CT对肺磨玻璃结节的影像特征及对良恶性的鉴别诊断作用。方法:抽取自2020年10月~2023年10月被本院接收的经病理确诊的60例肺磨玻璃结节患者为观察对象,对其先后行常规CT扫查和64排螺旋CT扫查,以病理性检查为诊断标准,比较两种检查方式的良、恶性结节检出率,分析影像学特征。结果:(1)影像学特征分析:60例患者的肺磨玻璃结节最大直径为(0.62±2.75)cm;病灶在左肺者占26例,病灶在右肺者占34例;病灶边缘规整的占28例,浅分叶的占20例,深分叶的占12例;瘤—肺界面模糊占24例,清晰占36例;病灶表面光滑占27例,毛刺征33例;血管集束征有38例,空泡征有15例,细支气管充气征有16例;病灶处血管穿行有35例,绕行有25例;支气管影不确切有11例,连续中断28例,走形僵硬且扭曲有21例;(2)经病理性检查确认,60例患者中,良性结节占29例,恶性结节占31例;常规CT扫查发现,良性结节占23例,恶性结节占25例;64排螺旋CT扫查发现,良性结节占28例,恶性结节占31例。就检出率进行比较,结果无统计学意义P>0.05;就病理诊断符合率进行比较,64排螺旋CT扫查均优于常规CT,数据在SPSS25.0统计学软件的统计分析下,比较结果表现为P<0.05。结论:64排螺旋CT扫查可以获取肺磨玻璃结节患者诸多病灶信息,对影像特征进行分析有助于良、恶性结节的鉴别诊断,对于早期确诊病情有重要意义,可为后期制定治疗方案奠定可靠的诊断依据。

Objective:To explore and analyze the imaging characteristics of ground glass nodules in the lungs using 64-slice spiral CT and its role in differentiating between benign and malignant lesions.Methods:60 patients with ground-glass pulmonary nodules diagnosed by pathology were selected from our hospital from October 2020 to October 2023 as the observation objects.Routine CT scan and 64-slice spiral CT scan were performed on them successively.Pathological examination was used as the diagnostic standard,and the detection rates of benign and malignant nodules were compared between the two methods,and the imaging characteristics were analyzed.Results:①Imaging characteristics analysis:The maximum diameter of pulmonary ground glass nodules in 60 patients was(0.62±2.75)cm;The lesions in the left lung accounted for 26 cases and the lesions in the right lung accounted for 34 cases.There were 28 cases with regular edges,20 cases with shallow lobed and 12 cases with deep lobed.The tumor-lung interface was blurred in 24 cases and clear in 36 cases.The surface of the lesion was smooth in 27 cases and burr in 33 cases.Vascular cluster sign in 38 cases,vacuole sign in 15 cases,bronchiole air sign in 16 cases;There were 35 cases of vascular crossing and 25 cases of detour.Bronchography was inaccurate in 11 cases,continuous interruption in 28 cases,rigid and distorted in 21 cases.②Pathological examination confirmed that 29 cases of benign nodules and 31 cases of malignant nodules were among the 60 patients.Routine CT scan showed that 23 cases were benign and 25 cases were malignant.64-slice spiral CT scan showed that 28 cases were benign and 31 cases were malignant.There was no significant difference in the detection rate(P>0.05).For comparison of pathological diagnosis coincidence rate,64-slice spiral CT scan was superior to conventional CT,and the data were statistically analyzed by SPSS25.0 statistical software,and the comparison result was P<0.05.Conclusion:64-slice spiral CT scan can obtain the information of many lesions in patients with ground-glass pulmonary nodules,and the analysis of image diagnosis is helpful for the differential diagnosis of benign and malignant nodules,which is of great significance for the early diagnosis of the disease,and can lay a reliable diagnostic basis for the formulation of treatment plan in the later stage.
