Comparative study of ultrasonography and computed tomography in the management of pelvic and pelviabdominal masses

ABSTRACT

To evaluate and compare the help which the clinical can get from U.S. and C.T. Scanning and to find out when one or both investigations should be done, 56 cases with pelvic or pelviabdominal masses were studied. These cases were prospectively studied by both U.S. and C.T. before surgical management. The results were compared with the findings of laparotomy or laparoscopy when indicated. U.s. and C.T. gave similar results in 37 cases [66%]. C.T. Was diagnostic but not U.S. in 15 cases [26.8%]. U.S. was diagnostic but not C.T. in 2 cases [3.6%]. False positive diagnosis of cysts by U.S. which were excluded by C.T. was found in 2 cases [3.6%]. Although both modalities are complementary, it can be concluded that sonography is the modality of choice for evaluation of uterine neoplasms that tend to be confined to the uterus. C.T. is better than U.S. in detecting extrauterine extension tumors. C.T. Can be considered as a second order diagnostic examination as it is relatively expensive and time consuming procedure
