Abstract：Objective To observe anatomic details of the rectal and its surrounding by high resolution magnetic resonance imaging(MRI), and provide anatomic parameters and basis for clinical diagnosis and treatment of rectal cancer. Methods The pelvic multiple sequence parameter MRI of 60 normal people and 20 cases of rectal cancer patients were collected and evaluated by two radiologists with double blind method. MRI was used for T staging in 20 patients with rectal cancer and the pathological results were compared. The display rate of anterior, posterior, left and right of fascia propria of 60 cases of normal rectal, and the presacral fascia, sacral fascia, retrorectal space, peritoneal reflextion, rectal lateral ligament, inferior hypogastric plexus of all research objects were statistically analyzed. Results High resolution MRI could display clearly the mucosa, submucosa and muscularis propria. The accuracy of MR in the preoperative T staging of rectal cancer was 80%(16/20). The display rate of anterior of fascia propria was 71.7% (43/60), posterior was 96.7% (58/60), left was 90.0% (54/60) and right was 83.3% (56/60). The display rate of Denonvillier′s fascia was 68.8%(55/80), anterior sacral fascia was 65.0%(52/80), sacral fascia was 87.8%(69/80), peritoneal reflextion was 86.3%(69/80) and inferior hypogastric plexus was 90.0%(72/80, the left of rectal lateral ligament was 3.8%(43/80) and right was 47.6%(38/80). Conclusions High resolution MRI can clearly display the anatomical details of the rectal and its surrounding, help clinical treatment with preoperative T staging, judge whether the circumferential resection margin infiltration and improve the micrometastasis operation resection rate and reduce the operation complications.
