In an effort to localize parathyroid lesions preoperatively, scanning with radioactive thallium and technetium was performed in 20 patients considered clinically to have hyperparathyroidism. In the 11 found at surgery to have single parathyroid adenomas, scanning correctly localized the lesion in 10; in the other patient the lesion was in the unscanned mediastinum. Preoperative scanning was not as rewarding in the seven patients with parathyroid hyperplasia. A thyroid lesion was the source of an abnormality seen on the parathyroid scan in one patient, while neck scanning and surgical exploration were negative in another. Comparison of the patients who had parathyroid adenomas localized in the neck with a control group of similar patients who did not undergo preoperative scanning showed that the average surgical time was reduced by 50% with preoperative localization and there was a decrease in the number of nonparathyroid tissue biopsies.
为了在术前定位甲状旁腺病变，对20例临床诊断为甲状旁腺功能亢进的患者进行了放射性铊和锝扫描。在手术中发现的11例单发甲状旁腺腺瘤患者中，扫描正确定位病变的有10例；另一例患者的病变位于未扫描的纵隔。术前扫描在7例甲状旁腺增生患者中效果不佳。1例患者甲状旁腺扫描显示异常的来源是甲状腺病变，而另1例患者颈部扫描和手术探查均为阴性。将颈部甲状旁腺腺瘤定位的患者与未进行术前扫描的类似患者对照组进行比较，结果显示术前定位使平均手术时间缩短了50%，非甲状旁腺组织活检的数量也有所减少。
