[Negative contrast in x-ray computed tomography. Preliminary study]. / Contraste négatif en tomodensitométrie. Etude préliminaire.

For the abdominal and pelvic CT Scan, the authors propose the filling of the bladder, the duodenal loop, the stomach and the rectum with a lipidic emulsion. The negative density of this emulsion allows a better visualization of the pancreas, the gastric wall and the bladder wall as well as the extension of pelvic and bowel tumors.
