摘要：

目的 探讨MSCT在孤立性肺内结节的诊断及鉴别诊断中的价值。方法 回顾性分析我院收治的68例80个结节的经手术CT定位穿刺病理证实为孤立性肺结节患者的临床资料，观察分析MSCT的诊断价值及其扫描图像特征。  68例80个结节中，病灶位于右肺48个，左肺32个；MSCT扫描诊断中肺腺瘤3例，错构瘤2例，腺癌46例，腺鳞癌10例，小细胞癌5 例，2例提示恶性组织但细胞类型不定。MSCT扫描结果与病理诊断结果存在一定差异，但差异无统计学意义（P>0.05）；MSCT扫描图像特征主要有毛刺征、分叶征、胸膜凹陷征、血管聚集征、空气支气管征和空泡征、磨玻璃密度影、伴淋巴结肿大。结论 MSCT利用它自身高密度分辨率和空间分辨率，大大地提高了肺内小结节的诊断准确率。

ABSTRACT: Objective To investigate the value of multi -slice spiral CT (MSCT) in the diagnosis and differential diagnosis of solitary pulmonary nodules. Methods The clinical data of 68 pulmonary nodules patients with 80 nodules comfirmed by surgery CT positioning puncture pathology were retrospectively analyzed. The diagnostic value of MSCT and its scanning image were observed and analyzed. Results In 68 patients with 80 pulmonary nodules, those were 48 lesions in the right and 32 lesions in the left; and there were 3 cases of lung adenoma, 2 cases of hamartoma, 46 cases of adenocarcinoma, 10 cases of carcinoma, 5 cases of small cell carcinoma and 2 cases suggesting malignant tissues but the cell types were uncertain in the MSCT scan diagnosis; there were some differences in the diagnosis results between MSCT and pathology, but the differences were not significant (P>0.05). MSCT scanning images had the features of spicule sign,
lobulation sign, pleural retraction sign, vascular clustering sign, air bronchogram and vacuole sign, ground glass opacity and lymphadenectasis. Conclusion MSCT greatly improve the the diagnosis accuracy of small nodules of lung using its own high-density resolution and spatial resolution.
