肺原位癌的CT征象分析

【摘要】 目的 分析肺原位癌的CT征象,为临床诊断提供参考。方法 回顾性分析2014年2月至2021年2月原位癌患者116例(128个病灶),分析磨玻璃结节的大小、形态、密度、毛刺、胸膜牵拉、同心圆征象、病灶内支气管形态、空泡征、CT值、病灶和血管的关系。结果肺原位癌大小为(6.6±2.2)mm,形态规则,密度均匀,多数无毛刺,部分有叶间胸膜牵拉和同心圆改变,CT值范围为(-564±152)HU,多数有血管穿行。结论 肺原位癌CT特征是密度均匀的磨玻璃结节,边界清楚,大小在6.6 mm左右,CT值大约在(-564±152)HU,邻近叶间胸膜时,可以引起叶间胸膜牵拉、移位,邻近血管在病灶内穿行。更多还原

【Abstract】 Objective To explore the diagnostic value of CT features of lung adenocarcinoma in situ.Methods A review of I 16 patients with lung adenocarcinoma in situ diagnosed in Hangzhou First People’s Hospital and Hangzhou Fuyang Women And Children Hospital from February 2014 to February2021 was conducted.A total of 128 lesions was analyzed,and the size,shape,density,and burrs of ground glass nodules,pleura,stretching,concentric signs,bronchial morphology in the lesion,vacuole sign,CT value,the relationship between the lesion and the blood vessel were analyzed.Results The average size of lung adenocarcinoma in situ was(6.6 ± 2.2)mm.The shape was regular and the density was uniform.Most of the lesions had no burrs,and some had interlobular pleural traction and concentric changes.The CT value range was(-564±152) HU,and most had blood vessels.Conclusion The CT features of lung carcinoma in situ are uniformly dense ground glass nodules with clear boundaries,about 6.6 mm in size,and CT value about(-564±152) HU,adjacent to the interlobular pleura.At this time,it can cause the interleaf pleura to be stretched and displaced,and adjacent blood vessels pass through the lesion.更多还原
