Abstract

Seventeen patients with pathologically proved rectal cancer were prospectively evaluated by CT and MR before surgery. MR were performed with intraluminal air injection to the rectum, and CT with contrast medium. We also compared dynamic MR with i.v. Gd-DTPA injection to T 2-weighted images (T 2 WI) in evaluating invasion of the proper muscular layer in 10 cases. CT was slightly superior to MR in evaluating metastatic perirectal lymph nodes probably due to higher spatial resolution. MR was fairly superior in diagnosis of the wall invasion and adjacent organ extension. The dynamic MR was less effective than T 2 WI because of lower spatial resolution and degraded signal-to-noise ratio.
