摘　　要：目的探讨64层螺旋CT对胃癌的诊断价值。方法对87例胃癌患者进行64层螺旋CT平扫及动态增强扫描,采用多平面重建(MPR)、仿真内镜(CTVE)技术重建分析,并进行TNM分期,与术后病理检查结果进行对照研究。结果 87例患者经螺旋CT诊断85例,64层螺旋CT对胃癌的检出率为97.7%,其中早期胃癌的检出率为66.7%,进展期胃癌的检出率为100%。多层螺旋CT(MDCT)对胃癌T分期准确率为83.9%,N分期准确率为72.4%,M分期准确率分92.0%。结论 64层螺旋CT对胃癌能进行较准确的诊断和TNM分期,对临床的诊断和治疗方案选择具有重要的指导价值。Objeetive To explore the diagnostic value of 64 layers spiral CT for gastric carcinoma. Methods The 87 patients （primarily diagnosed gastric carcinoma ）were studied and scanned under 64 layers spiral CT including plain scans and enhanced scans respectively. The source images were reconstructed using the technique of multilane volume reconstruction （MPVR） and CT virtual endoscopy （CTVE） and conducting TNM stage, then compared to histopathology results after surgery. Results 85 out of 87 patients with gastric carcinoma were diagnosed by CT. Detection rate of multi-detector CT（MDCT） for gastric cancer was 97.7%, while the early stage and advanced stage gastric carcinoma were 66.7% and 100% respectively. The accuracies of 64 layers spiral CT for the T stage,the N stage and the M stage of the gastric carcinoma were 83.9%,72.4% and 92.0% respectively. Coneluslon 64 layers spiral CT could be helpful for the diagnosis of gastric carcinoma and TNM stage. It might play great roles for the diag- nosis and treatment of gastric carcinoma.
