Thallium-201 subtraction scintigraphy has been used in Wellington Hospital for preoperative localisation of parathyroid adenomas since 1984. The technique wa audited by comparing the scan reports with the outcome at operation in 33 patients, 30 of whom underwent a primary exploration. In our unselected patients we found the technique to have poor sensitivity (45.4%) with a high false positive rate (21%). There was no difference in the mean size of the glands correctly identified compared to those that were missed. Our experience has led us to believe that thallium-201 subtraction scintigraphy has not lived up to its early promise and is not a useful technique for routine preoperative localisation of parathyroid adenomas.
自1984年以来，铊-201减影闪烁扫描术一直在惠灵顿医院用于术前甲状旁腺腺瘤的定位。通过将扫描报告与33例患者的手术结果进行比较，对该技术进行了审核，其中30例患者接受了初次探查。在我们未经过挑选的患者中，我们发现该技术敏感性较差（45.4%），假阳性率较高（21%）。与未被识别的腺体相比，正确识别的腺体平均大小并无差异。我们的经验使我们相信，铊-201减影闪烁扫描术并未达到其早期的预期效果，并非术前常规定位甲状旁腺腺瘤的有用技术。
