Computed tomography of the pelvis.

The computed tomography scan has revealed the location and size of abnormal pelvic masses as an adjunct to other diagnostic studies. We have extended its usefulness by air distension of the bladder, which accommodates to adjacent structures and, therby, highlights abnormalities in its own wall and in other organs. The patients are prepared according to a simple routine. As we attempt further economy and efficiency the cost of each study becomes justified by the information gained.
