Colorectal Carcinoma: Local Tumor Staging and Assessment of Lymph Node Metastasis by High-Resolution MR Imaging in Surgical Specimens
Figure 4
Colorectal carcinoma involving the muscularis propria. (a) High-resolution T2-weighted MR image (2000/70) shows that an irregularly-shaped tumor partially replaces the muscularis propria layer (arrow), but that it does not penetrate through the muscularis propria layer. There is a deep ulceration in the central part of the tumor. (b) Corresponding histopathologic section shows carcinoma involving the muscularis propria (arrow) which manifests a deep ulceration in the central part.
