A prospective evaluation of computed tomography and ultrasound was performed on 24 consecutive patients with suspected pelvic masses. Of the 24 patients, 22 had subsequent surgical identification of abnormalities; two were considered normal on clinical follow-up. Ultrasound provided important clinical information in 17 of 24 patients; CT in 15 of 24 patients. There were three false negative examinations with each method and no false positives. Differentiation between benign and malignant disease could not be made in four of 24 patients by ultrasound and five of 24 patients by CT. Because both imaging techniques depict similar pathology and use similar diagnostic criteria, the two methods tend not to be complementary.
对24例连续的疑似盆腔肿块患者进行了计算机断层扫描（CT）和超声的前瞻性评估。24例患者中，22例随后经手术确定存在异常；2例在临床随访中被认为正常。超声为24例患者中的17例提供了重要临床信息；CT为24例患者中的15例提供了重要临床信息。两种方法均有3例假阴性检查，无假阳性。24例患者中，超声检查有4例无法区分良性和恶性疾病，CT检查有5例无法区分。由于两种成像技术显示的病理相似且使用相似的诊断标准，这两种方法往往不具有互补性。
