In a series of 99 pelvic ultrasound examinations for suspected gynecologic masses, there were 72 established tissue diagnoses. The ultrasound diagnosis was correct in 61 (85 per cent). The specificity, based on a small number (six) of actual negative cases, was 67 per cent. The sensitivity, based on 57 actual positive cases, was 100 per cent. The ultrasound pattern of a homogeneous solid mass obscuring part or all of the uterine border was commonly associated with an erroneous diagnosis. When this pattern is seen, examination of the patient with higher frequency transducers provides useful information that supplements high- and low-gain scans.
在针对疑似妇科肿块进行的99次盆腔超声检查中，有72例确诊为组织病变。超声诊断正确的有61例（85%）。基于少量（6例）实际阴性病例得出的特异性为67%。基于57例实际阳性病例得出的敏感性为100%。均匀实性肿块遮挡部分或全部子宫边界的超声图像通常与错误诊断相关。当出现这种图像时，使用更高频率的换能器对患者进行检查可提供补充高增益和低增益扫描的有用信息。
