Abstract

The purpose of this prospective study was to assess the accuracy of endorectal MR imaging in the preoperative local staging of rectal cancers. In 20 cases, we correlated endorectal MR imaging findings with postoperative histopathologic staging according to TNM classification. The accuracy of endorectal MR for determining the T stage of rectal cancer was 85%. The sensitivity and specificity for detecting lymph node metastases were 90.9% and 55.5%, respectively.

摘要

这项前瞻性研究的目的是评估直肠内磁共振成像在直肠癌术前局部分期中的准确性。在20例患者中，我们根据TNM分类将直肠内磁共振成像结果与术后组织病理学分期进行了对比。直肠内磁共振成像确定直肠癌T分期的准确性为85%。检测淋巴结转移的敏感性和特异性分别为90.9%和55.5%。
