目的加深对周围型小肺癌高分辨螺旋CT(HRSCT)表现的认识,提高其诊断准确率。方法收集2002年05月～2005年06月螺旋CT诊断、临床病理或随访证实的周围型小肺癌35例进行回顾性分析。结果周围型小肺癌的主要HRSCT征象有:分叶征30例,边缘细短毛刺征26例,空泡征和(或)空气支气管征15例;次要HRSCT征象有:血管支气管集束征14例,胸膜凹陷征13例,胸膜尾征6例,磨玻璃征2例,蜂窝征2例。结论高分辨螺旋CT扫描(HRSCT)能够清晰显示周围型小肺癌的形态、边缘、密度及其与邻近组织的关系,在周围型小肺癌的诊断中有重要价值。
Objective To deepen the understanding of the performance of high resolution spiral CT (HRSCT) in peripheral small lung cancer and to improve its diagnostic accuracy. Methods From May 2002 to June 2005, 35 cases of peripheral small lung cancer diagnosed by clinic, pathology or follow-up were retrospectively analyzed. Results The main signs of HRCTT in peripheral small lung cancer were: lobulation sign in 30 cases, margin slender burr sign in 26 cases, vacuole sign and / or air bronchus sign in 15 cases. The secondary signs of HRSCT were: bronchial bundling sign in 14 cases Pleural indentation in 13 cases, pleural tail sign in 6 cases, ground glass sign in 2 cases and honeycomb sign in 2 cases. Conclusions High resolution spiral CT scan (HRSCT) can clearly show the shape, margins and density of peripheral small lung cancer and its relationship with adjacent tissues. It is of great value in the diagnosis of peripheral small lung cancer.
