Abstract

Stringent quality control cannot be overemphasized in performing SPECT. SPECT artifacts related to camera uniformity, center of rotation, and the patient's motion are well recognized. In this communication, another rare cause of a SPECT artifact related to a triad system is reported. A triple-headed SPECT system was accidentally equipped with two ultrahigh-resolution collimators and a general all-purpose collimator during a brain SPECT study, causing a false cerebral blood flow defect.

摘要

在进行单光子发射计算机断层扫描（SPECT）时，严格的质量控制再怎么强调也不为过。与相机均匀性、旋转中心和患者运动相关的SPECT伪影已广为人知。在本通讯中，报告了另一种与三联系统相关的SPECT伪影的罕见原因。在一项脑SPECT研究中，一个三头SPECT系统意外地配备了两个超高分辨率准直器和一个通用的全用途准直器，导致了虚假的脑血流缺损。
