Single photon emission computed tomography (SPECT) is becoming an increasingly important part of routine clinical nuclear medicine. By providing tomographic reconstructions in multiple planes through the patient, SPECT expands the clinical applications in nuclear medicine as well as providing better contrast, edge definition and separation of target from background activities. Imaging techniques have been developed for the evaluation of regional cerebral blood flow using radiolabeled amines. Thus cerebral functional imaging can be used in the diagnosis of acute cerebral infarction, cerebral vascular disease, dementia and epilepsy. SPECT plays a complementary role in the evaluation of coronary artery disease, particularly when it is coupled with thallium-201 and exercise testing. SPECT extends our diagnostic capabilities in additional areas, such as liver and bone scintigraphy as well as tumor imaging with gallium-67.
单光子发射计算机断层扫描（SPECT）正日益成为常规临床核医学的重要组成部分。通过对患者进行多平面断层重建，SPECT扩展了核医学的临床应用，同时提供了更好的对比度、边缘清晰度以及目标与背景活性的分离。已经开发出使用放射性标记胺来评估局部脑血流量的成像技术。因此，脑功能成像可用于诊断急性脑梗死、脑血管疾病、痴呆和癫痫。SPECT在冠状动脉疾病的评估中发挥着补充作用，特别是当它与铊-201和运动试验相结合时。SPECT还扩展了我们在其他领域的诊断能力，如肝脏和骨闪烁显像以及用镓-67进行肿瘤成像。
