摘要: PURPOSE: To evaluate signal intensity and border characteristics of lymph nodes at high-spatial-resolution magnetic resonance (MR) imaging in patients with rectal cancer to compare these findings size prediction nodal status. MATERIALS AND METHODS: Forty-two who underwent total mesorectal excision the rectum determine if they had carcinoma were studied preoperative thin-section MR imaging. Lymph harvested from 42 transversely sectioned surgical specimens. The slice each node was carefully matched its location on corresponding images. Nodal size, contour, images characterized related histologic involvement metastases. Differences sensitivity specificity or calculated CIs by using method 10 Newcombe. RESULTS: Of 437 harvested, 102 too small (<3 mm) be depicted images, only two contained I...
