目的评估真横断位CT在结肠癌分期中的准确性。方法由3名具有结直肠癌分期经验的放射医师对50个连续的数据组进行独立评估。第一次阅片只是标准的横断位影像。6周后的第2次阅片包括了真横断位影像,即在肿瘤生长区垂直于肿瘤长轴的影像。结果阅读标准的横断位 Objective To evaluate the accuracy of true transverse CT in staging of colon cancer. Methods Fifty consecutive data sets were independently evaluated by three radiologists with staging of colorectal cancer. The first reading is only a standard transverse position of the image. The second reading after 6 weeks included true transverse transection images, ie, images perpendicular to the long axis of the tumor in the tumor growth zone. Results read the standard transverse position
