Preoperative staging of rectal cancer is critical for guiding therapy and prescribing the most appropriate treatment option. The purpose of this investigation was to compare the accuracy of endorectal surface coil magnetic resonance imaging (ERSCMRI) with endosonography (EUS) in staging rectal lesions.
Fourteen patients with rectal carcinoma, initially detected by barium enema or sigmoidoscopy underwent ERSCMRI and EUS. Subsequent resection of the lesions was performed, and the staging accuracies of these two modalities are compared.
MR T-staging agreement with pathologic T-staging was similar to that of EUS, but MR enabled more accurate identification of nodal involvement.
ERSCMRI produced greater overall accuracy in staging for rectal carcinoma than did EUS.
直肠癌的术前分期对于指导治疗和选择最合适的治疗方案至关重要。本研究的目的是比较直肠内表面线圈磁共振成像（ERSCMRI）与内镜超声检查（EUS）对直肠病变进行分期的准确性。
14例最初通过钡灌肠或乙状结肠镜检查发现的直肠癌患者接受了ERSCMRI和EUS检查。随后对病变进行切除，并比较这两种检查方法的分期准确性。
MR T分期与病理T分期的一致性与EUS相似，但MR能够更准确地识别淋巴结受累情况。
与EUS相比，ERSCMRI对直肠癌分期的总体准确性更高。
