Colon carcinoma: MR imaging with CO2 enema--pilot study

Radiology. 2001 May;219(2):558-62. doi: 10.1148/radiology.219.2.r01ma10558.


Prior to surgery, seven patients with known colonic tumors underwent breath-hold single-shot fast spin-echo magnetic resonance imaging during a CO2 enema. The images were evaluated for depiction of tumor, adjacent structures, and the remaining colon, and findings were compared with findings at surgery. In all seven patients, the tumor was demonstrated, and in four (57%), breach of the muscularis propria was correctly predicted.
