Computed tomography (CT) has been performed in 21 patients with primary hyperparathyroidism (HPT) in an attempt to localize preoperatively the parathyroid tumors. Eighteen of these patients also had ultrasound examinations. The CT examinations included the neck and mediastinum and were performed before and after contrast medium administration. At subsequent surgery, 24 enlarged glands were found, 20 in the neck and 4 in the mediastinum. In the neck, two were locally recurrent carcinomas. The true positive diagnostic rate for ultrasound was 60% with a false positive rate of 15% and a false negative rate of 25%. The CT examinations resulted in 70.9% true positive, 8.3% false positive, and 20.8% false negative diagnoses. The combination of both methods in the 18 patients so studied resulted in 80% true positive, 10% false positive, and 10% false negative findings. The CT examination procedure and its interpretation and limitations in primary HPT are described.
对21例原发性甲状旁腺功能亢进症（HPT）患者进行了计算机断层扫描（CT），试图在术前定位甲状旁腺肿瘤。其中18例患者还接受了超声检查。CT检查包括颈部和纵隔，在注射造影剂前后进行。在随后的手术中，发现24个增大的腺体，20个在颈部，4个在纵隔。在颈部，有两个是局部复发性癌。超声检查的真阳性诊断率为60%，假阳性率为15%，假阴性率为25%。CT检查的真阳性诊断率为70.9%，假阳性率为8.3%，假阴性率为20.8%。对这18例患者同时采用两种方法检查，结果真阳性率为80%，假阳性率为10%，假阴性率为10%。本文描述了CT检查方法及其在原发性HPT中的解读和局限性。
