A technetium-thallium (99mTcO4-201Tl) subtraction scan was performed in a patient with clinical and biological evidence of hyperparathyroidism. The 201Tl image indicated a normal thyroid gland. The 99mTcO4 image revealed a left inferior thyroidal extension with an intense and transient focus corresponding to an ultrasonographic nodule. The transient character of the focus was not explicable in terms of vascular kinetics. A supplementary scintigram using 123I confirmed the presence of an inferior extension of the thyroid, but no increased uptake was found. A nodule weighing 250 mg containing a parathyroid adenoma surrounded by normal thyroidal tissue was excised at the focus site. Biological serum levels returned to normal after the operation. It is concluded that the analysis of 99mTcO4 dynamic data could improve the accuracy of parathyroid subtraction scintigraphy.
对一名有甲状旁腺功能亢进临床和生物学证据的患者进行了锝-铊（99mTcO4-201Tl）减影扫描。201Tl图像显示甲状腺正常。99mTcO4图像显示甲状腺左下叶有一延伸部分，伴有一个与超声检查发现的结节相对应的强烈且短暂的显像剂浓聚灶。该浓聚灶的短暂特性无法用血管动力学来解释。使用123I的补充闪烁扫描证实了甲状腺左下叶的存在，但未发现摄取增加。在浓聚灶部位切除了一个重250mg、含有甲状旁腺腺瘤且被正常甲状腺组织包绕的结节。术后生物学血清水平恢复正常。结论是，分析99mTcO4动态数据可提高甲状旁腺减影闪烁显像的准确性。
