New barium paste mixture for helical (slip-ring) CT evaluation of rectal carcinoma.
We describe a new method for complete opacification of the rectum using helical CT and a newly developed anal contrast agent. Rectal cancers were easily identified in all of the 21 patients examined, and diagnostic accuracy in detecting local invasion was 94%. Our method of rectal CT is easy to perform and well tolerated.
