Four-dimensional computed tomography protocol for preoperative evaluation of the parathyroid glands and its correlations with other imaging methods: a pictorial essay

Abstract Parathyroid adenoma is the most common cause of primary hyperparathyroidism. Advances in surgical techniques have made it possible to excise only the affected parathyroid gland in most cases. Imaging examinations play a fundamental role in the preoperative planning of parathyroidectomy. To localize the parathyroid glands, imaging tests such as scintigraphy, ultrasound, and, more recently, four-dimensional computed tomography (4D CT). The aim of this pictorial review was to illustrate the use of the 4D CT protocol in cases of parathyroid adenoma and to determine how well it correlates with other imaging methods, in order to improve understanding of the 4D CT method.

【摘要】甲状旁腺腺瘤是原发性甲状旁腺功能亢进最常见的病因。外科手术技术的进步使得多数病例仅需切除受累甲状旁腺成为可能。影像学检查在甲状旁腺切除术的术前规划中具有基础性作用。为定位甲状旁腺，临床常用放射性核素显像、超声以及近年来兴起的四维计算机断层扫描（four-dimensional computed tomography，4D CT）等影像学检查手段。本影像综述旨在阐明4D CT检查方案在甲状旁腺腺瘤病例中的应用，并探讨其与其他影像学方法的相关性，以期提升对4D CT技术的理解与认知。
