Eighty-seven patients who had sonographic examinations at the Orange County Medical Center were studied retrospectively to evaluate the usefulness and reliability of this noninvasive technique, and sonographic results were compared with findings at operation or findings made using other diagnostic methods. With a variety of lesions, the overall accuracy of diagnosis by sonography was 85%. In the remaining 15% of studies, false-positive or false-negative results were observed. The accuracy varied with the organ involved, the greatest being renal and hepatic masses. Ultrasound, when used in addition to careful surgical assessment of the patient, was found to be most useful in the diagnosis and follow-up of abdominal problems in surgical patients.
对在奥兰治县医疗中心接受超声检查的87例患者进行回顾性研究，以评估这种非侵入性技术的实用性和可靠性，并将超声检查结果与手术所见或其他诊断方法的结果进行比较。对于各种病变，超声诊断的总体准确率为85%。在其余15%的研究中，观察到假阳性或假阴性结果。准确率因受累器官而异，最高的是肾和肝肿块。超声检查在对患者进行仔细的手术评估之外使用时，被发现对手术患者腹部问题的诊断和随访最为有用。
