高分辨MSCT薄层重组在常规胸部体检中的应用

目的：探讨多排螺旋CT（MSCT）高分辨薄层重组对体检中肺部疾病的诊断价值,以及MSCT薄层重组与常规CT扫描图像质量及诊断准确率对照。方法：搜集做64排常规CT扫描同时行薄层重组的2473例体检病例中筛选的97例患者进行回顾性分析。结果：97例患者在常规CT扫描中有80例可以显示病变,而在MSCT薄层重组中97例均有阳性发现;其中双肺弥漫性病变79例（两肺间质纤维化78例,肺内多发转移瘤1例）,肺结核3例,肺内孤立结节12例,早期中央型肺癌1例,先天性支气管闭锁1例以及纵隔肿瘤1例;MSCT薄层重组图像可清晰显示肺内小叶间隔线增厚、弥漫分布的囊性病变、肺内结节的细微征象。结论：MSCT薄层重组在胸部体检中的诊断阳性率、细节分辨率、图像质量及确诊率均优于常规CT,可作为肺内病变尤其是早期肺癌筛查方法之首选。

Application of Thin-Reconstruction with High-Resolution MSCT in Conventional Physical Examination in Chest

Objective：To evaluate the clinical value of thin-reconstruction with high-resolution MSCT and routine CT of chest in diagnosis of lung disease in people who had conventional physical examination.Methods：Ninety-seven patients of lung disease,all underwent routine CT and thin-reconstruction with high-resolution MSCT with 64 slices CT scanner.Results：80 cases were displayed disease region by routine CT,all of the 97 cases have positive findings by thin-reconstruction with high-resolution MSCT.Conclusion：There were some difference in diagnosis of lung disease between routine CT and thin-reconstruction with high-resolution MSCT,MSCT reconstructions has higher rate of positive in diagnosis,resolution in details and definte rate.thin-reconstruction with high-resolution MSCT could be first used in conventional physical examination in chest.
