Computed Tomography in the Evaluation of Carcinoma of the Ovary

Abstract
Over 26 mo., 34 patients with histologically proven ovarian malignancy were studied by computed tomography (CT). In 9 patients, CT was obtained for evaluation of a pelvic or abdominal mass. CT was diagnostic of ovarian malignancy in 7 and indeterminate regarding the origin of the tumor in 2 patients. Ten patients were evaluated by CT to rule out recurrent ovarian neoplasm. Disease free intervals prior to CT ranged from 6-36 mo. with an average of 18 mo. In 8 surgically proven cases, CT was true positive for recurrent tumor in 6 patients, true negative in 1 and false positive in 1. In 20 patients, serial CT examinations were valuable in the objective assessment of measurable tumor response following chemotherapy and radiation therapy. A major limitation of CT was its inability to detect peritoneal and liver surface implants smaller than 2 cm in size.
