Abstract

Combining myocardial perfusion single photon emission computed tomography (SPECT-MPI) and coronary computed tomography angiography (CCTA) is an interesting hybrid imaging option in modern cardiovascular medicine. The integrated hybrid technique has a number of advantages compared to visual side-by-side analysis of the separate modalities. CT attenuation map can correct for attenuation artefacts and thus improve the diagnostic accuracy of SPECT-MPI. Moreover, the anatomical information of the CCTA and the perfusion map of SPECT-MPI allow for vessel-based correlation and culprit vessel identification. Combining SPECT-MPI with CCTA is an appealing tool in the work-up of complex ischaemic heart disease and might help determine the optimal treatment strategy. This case series illustrates the role of SPECT-CCTA in decision-making of revascularization strategy in complex ischaemic heart disease.

摘要

结合心肌灌注单光子发射计算机断层扫描 (SPECT-MPI) 和冠状动脉计算机断层扫描血管造影 (CCTA) 是现代心血管医学中一种有趣的混合成像选择。与单独模态的视觉并排分析相比，集成混合技术具有许多优点。CT 衰减图可以校正衰减伪影，从而提高 SPECT-MPI 的诊断准确性。此外，CCTA 的解剖信息和 SPECT-MPI 的灌注图允许基于血管的相关性和罪魁祸首血管识别。将 SPECT-MPI 与 CCTA 结合是复杂缺血性心脏病检查的一个有吸引力的工具，可能有助于确定最佳治疗策略。
