    【摘 要】目的探讨3.0T磁共振对直肠癌术前分期的临床应用价值，以指导直肠癌的个体化治疗。方法利用3.0T磁共振对46例经结肠镜证实的直肠癌患者进行盆腔检查，然后由两名腹部影像诊断医师共同阅片，对直肠癌进行术前MR-T、N分期，然后与手术病理结果进行对照分析。结果MR-T分期正确率为86.9%(40/46)，直肠癌MRI-T分期与术后病理T分期的一致性良好。N分期的正确率为73.9%(34/46)，直肠癌MRI-N分期与术后病理N分期的一致性一般。结论高分辨率3.0T磁共振成像可以对直肠癌做出准确的术前局部分期。

    Abstract? Objective? The purpose of this study was prospectively to determine the accuracy and the ability to delineate lesions of high resolution magnetic resonance imaging for preoperative local staging of rectal carcinoma. So that to guide the individual treatment of patients with rectal cancer. Methods? Forty-six patients with histopathologically proven underwent preoperative Pelvic MR examination with 3.0T MRI. And then two experienced abdomen radiologists read the images together in consensus ......
