99mTc-MIBI 闪烁扫描是一种核医学成像方式，常用于甲状旁腺功能亢进症患者甲状旁腺腺瘤的术前定位。此外，99mTc-MIBI由于其独特的细胞内积累机制，还可用于多种肿瘤的成像。在此，我们介绍了一位甲状旁腺功能亢进症患者的单次 99mTc-MIBI SPECT/CT 同时显示两种不同恶性肿瘤（如乳头状甲状腺癌和小细胞肺癌）以及甲状旁腺腺瘤的病例。还通过将 99mTc-MIBI SPECT/CT 与三种肿瘤中的 18F-FDG PET/CT 进行比较，探讨了 99mTc-MIBI SPECT/CT 的临床实用性。版权所有 © 2024 Wolters Kluwer Health, Inc. 保留所有权利。

99mTc-MIBI scintigraphy is a nuclear medicine imaging modality commonly used for the preoperative localization of parathyroid adenomas in patients with hyperparathyroidism. In addition, 99mTc-MIBI can also be used for imaging various tumors due to its unique mechanism of intracellular accumulation. Here, we introduced a case of a single 99mTc-MIBI SPECT/CT simultaneously visualized two different malignant tumors, such as papillary thyroid cancer and small cell lung cancer, along with a parathyroid adenoma in a patient with hyperparathyroidism. The clinical usefulness of 99mTc-MIBI SPECT/CT was also explored by comparing it with 18F-FDG PET/CT among the three tumors.Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.
