摘　　要：目的:探讨多层螺旋CT(MSCT)扫描及后处理三维重建在胃肠道疾病方面的诊断价值。方法:收集65例经手术或内窥镜活检证实胃肠道疾病的MSCT三维重建并与大体病理解剖对照;所有病例均运用16层MSCT进行螺旋扫描,扫描后运用后处理图像技术多平面重建(MPR)、CT仿真内窥镜(CTVE)、表面遮盖显示(SSD)、透明显示(Raysum)三维重建。结果:65例中后处理重建技术诊断准确39例;对病变大小、形态、癌肿向周围侵犯的程度、肿瘤灶周血供等情况清楚显示。结论:MSCT结合后处理三维重建技术在胃肠道疾病诊断方面具有一定的优势,尤其是胃肠道肿瘤的定位、病变累及的范围等具有较高的诊断价值。Objective： To explore the value of diagnosis in the gastrointestinal disease with Multi-slice Spiral CT and post processing 3D reconstruction.Methods： To collect the clinical data of 65 cases of 3D reconstruction with Multi-slice Spiral CT.All cases were confirmed by surgery,pathology,and compared with large patho-anatomy.The cases were also employed 16 Multi-slice Spiral CT scanning.After CT scanning,the cases were received multiplanar reconstruction,virtual endoscopy,resurfacing and raysum.Results： Of the 65 cases,39 cases were collectly diagnosed by post processing pictorial technique and were clearly displayed pathological changes of size and shape.Conclusion： Multi-slice Spiral CT combined with post processing pictorial technique has some advangtages in diagnosis of gastrointestinal diseases and gastrointestinal tumor.
