The utility of preoperative parathyroid location in primary hyperparathyroidism (pHPT) remains controversial. In this retrospective study are analysed noninvasive techniques prior to surgical neck exploration of 11 patients with pHPT, ten adenomas and one hyperplastic parathyroid glands. Localization test were performed 24 times. Ultrasonography allowed correct localization of 5 of 7 cases, computer tomography 2 of 6, scintigraphy 2 of 4 and nuclear magnetic resonance 1 of 7. This exploration was doubtful in a patient, and two false-positive nuclear magnetic resonance were found. The low yield of these tests makes them unnecessary in the evaluation of patients undergoing surgery for pHPT, because the cost is not justified.
术前甲状旁腺定位在原发性甲状旁腺功能亢进症（pHPT）中的作用仍存在争议。在这项回顾性研究中，分析了11例pHPT患者（10例腺瘤和1例甲状旁腺增生）在颈部手术探查前的非侵入性技术。共进行了24次定位检查。超声检查在7例中正确定位了5例，计算机断层扫描在6例中定位了2例，闪烁扫描在4例中定位了2例，核磁共振在7例中定位了1例。1例患者的探查结果存疑，且发现了2例假阳性的核磁共振检查结果。这些检查的低阳性率使得它们在评估接受pHPT手术的患者时没有必要，因为成本效益不合理。
