Colorectal Carcinoma: Local Tumor Staging and Assessment of Lymph Node Metastasis by High-Resolution MR Imaging in Surgical Specimens
Figure 8
Benign lymph nodes showing high signal intensity on high-resolution T2-weighted images and smooth border contour. (a) High-resolution T2-weighted MR image (2000/70) shows lymph nodes (arrow) having high signal intensity and smooth border contour in the subserosal fat. The chemical shift artifact (arrowheads) is noted. (b) High-resolution T1-weighted MR image (500/20) shows lymph nodes (arrow) having smooth border contour. The chemical shift artifact (arrowheads) is noted. (c) Corresponding histopathologic section shows benign lymph nodes (arrow) in the subserosa.
