多层螺旋CT对结节型细支气管肺泡细胞癌的诊断价值研究

摘要

Objective To evaluate the multi-slice spiral computed topography in diagnosis value of nodule bronchioalveolar carcinoma.Methods CT and pathologic finds of 37 cases of nodule bronchioalveolar carcinoma were studied through retrospective research.Results Peripheral 31 cases(83.8%),lobulation 17 cases(45.9%),air bronchogram 19 cases(51.4%),vacules 12 cases(32.4%),necrosis in tumor 7 cases(18.9%),soiculation 24 cases(64.9%),aggregation of vascular bundle 23 cases(62.6%),pleural traction 23 cases (62.6%).Conclusion NABC has its typical imaging features,and NBAC can be clearly delineated on MSCT combined with muitiple sectiones images to reduce misdiagnose effectively.%目的 探讨多层螺旋CT(MSCT)对结节型细支气管肺泡癌(Nodule Bronchioloalveolar Carcinoma,NBAC)的诊断价值.方法 回顾性研究37例NBAC的CT表现并与病理进行对照分析.结果 周围型83.8%(31/37),中心性16.2%(6/37),磨玻璃征51.4%(19/37),呈分叶状改变45.9%(17/37),内部可见充气支气管征51.4%(19/37),空泡征32.4%(12/37),中心坏死18.9%(7/37),边缘毛刺64.9%(24/37).血管集束征62.6%(23/37)、胸膜凹陷征62.6%(23/37),病灶大小14~46mm.结论 NBAC影像表现具有一定特征性,MSCT扫描结合多平面重组有利于提高NBAC诊断准确性,以减少误诊发生.
