多排螺旋CT技术在诊断和鉴别早期周围型小肺癌中的临床应用

Multi-slice spiral CT in diagnosis and differential diagnosis of early small peripheral lung cancer

目的：探讨多排螺旋CT在诊断和鉴别诊断早期周围型小肺癌中的临床价值。方法：回顾性分析2010年1月-2014年1月96例早期周围型小肺癌患者,均予多排螺旋CT进行扫描,观察其在影像学表现情况。结果：在CT上,病灶主要集中在左肺上,病灶大小以8~15mm为主结节内部主要表现为毛玻璃样密度小泡征和密度不均匀呈小颗粒堆积状,病灶边缘分叶较深,病灶周围14例可见胸膜边缘呈现磨玻璃样晕影,30例见有线影,胸膜凹陷征40例,支气管血管聚集征9例;增强扫描后,病灶均匀强化29例,不均匀强化67例,病灶时间密度曲线呈缓慢升高型。结论：多排螺旋CT可作为诊断和鉴别诊断早期周围型小肺癌的首选影像学检查。

Objective： To investigate the multi-slice spiral CT clinical value of early diagnosis of small peripheral lung cancer. Methods： To retrospectively analyze 96 early small peripheral lung cancer patients with exam of multi-slice spiral CT scanning. Results： On CT,the lesions mainly in the left lung,nodular lesion size were 8 ~ 15 mm dominated mainly for internal vesicles levy ground glass density and density were uneven accumulation of small particles like lesions darker leaf edge lesions were seen around 14 cases of pleural presented ground-glass edge vignetting,30 cases wired shadow,pleural indentation 40 cases,9 cases of bronchial vessels gathered levy. After enhanced scan lesions homogeneous enhanced in 29 cases,67 cases of heterogeneous enhanced,lesions showed a slow rise time density curve. Conclusion： Multi-slice spiral CT can be used as an early diagnosis and differential diagnosis of small peripheral lung cancer for imaging.
