摘　　要：目的:探讨多层螺旋CT平扫及重建在结肠肿瘤诊断上的临床应用价值。方法:选自经手术治疗的结肠癌和结肠息肉患者152例,其中结肠癌121例,结肠多发息肉31例。所有病例术前均行16层螺旋CT和纤维大肠镜检查。阅CT图像,诊断结肠癌的Borrmmann类型、T分期;判定结肠息肉的检出率和恶变情况,并与术后病理对照。结果:依据多层螺旋CT判定结肠癌大体分型的准确率为95.9%;诊断T分期的准确率为81.0%;多层螺旋CT平扫及各种重建影像检出结肠息肉与病理所见具有同一性(P<0.05)。结论:MPR是应用多层螺旋CT诊断结肠肿瘤中最为实用的基础方法。多层螺旋CT平扫及重建在结肠肿瘤诊断上具有明显的临床应用价值。Objective：To investigate the application of multi - slice spiral CT scanning and reconstructions in diagnoslng colon neoplasm. Methods： Total to 121 patients with advanced colon carcinoma and 31 patients with polypus in colon were examined with 16 - slice spiral CT and colonofibroscope before operation. Then all the patients accepted operations. The CT results of judging Borrmann typing, T- stage of colon carcinomas and diagnostic rates of colon polypus were compared with surgical and pathological findings. Results： In diagnosing advanced carcinoma of large intestine by multi -slice spiral CT, the accuracy of judging Borrmann typing was 95.9% ; the accuracy of jud- ging T - stage was 81.0% ; it＇s accurate to diagnose colon polypus by multi - slice spiral CT compared with pathological findings. Conclusion： MPR is the best method to display colon neoplasm. Multi -slice spiral CT is valuable in diagnosing colon neoplasm.
