Y. Ogawa et al., NEW BARIUM PASTE MIXTURE FOR HELICAL (SLIP-RING) CT EVALUATION OF RECTAL-CARCINOMA, Journal of computer assisted tomography, 21(3), 1997, pp. 398-401
We describe a new method for complete opacification of the rectum usin
g helical CT and a newly developed anal contrast agent, Rectal cancers
were easily identified in all of the 21 patients examined, and diagno
stic accuracy in detecting local invasion was 94%. Our method of recta
l CT is easy to perform and well tolerated.
