The clinical experience with the Toshiba GCA-9300A single photon emission tomography (SPET) system is discussed along with typical acquisition protocols for various SPET studies. The system was used to perform SPET studies in normals and in a variety of brain and body disorders. Its three Anger-type gamma cameras forming a triangular aperture offer a substantial increase in sensitivity compared to a single rotating gamma camera. This has allowed the routine use of lead fanbeam super high-resolution collimators (SHR FB) for 99Tcm-hexamethylpropyleneamine oxime (HMPAO) brain SPET studies and high-resolution parallel-hole collimators (HR PH) for cardiac and other body studies. The resulting improvement in spatial resolution coupled with the ease of patient positioning and the greater patient throughput compared to a conventional tomographic gamma camera, will enhance the role of brain and body SPET for both routine and research purposes.
本文讨论了东芝GCA - 9300A单光子发射断层扫描（SPET）系统的临床应用经验以及各类SPET研究的典型采集方案。该系统用于对正常人和各种脑部及身体疾病患者进行SPET研究。其由三个安格型伽马相机组成三角形孔径，与单个旋转伽马相机相比，灵敏度大幅提高。这使得在99Tcm - 六甲基丙烯胺肟（HMPAO）脑SPET研究中常规使用铅扇束超高分辨率准直器（SHR FB），在心脏和其他身体研究中使用高分辨率平行孔准直器（HR PH）。与传统断层伽马相机相比，空间分辨率的提高、患者定位的便利性以及更大的患者通量，将提升脑和身体SPET在常规和研究目的中的作用。
