Myocardial Perfusion Imaging and other Modalities
- Pp. 87-103 (17)Yasuyo Taniguchi
Rapid technological advance has brought many myocardial perfusion imaging (MPI) modalities other than myocardial single-photon emission computed tomography (SPECT) imaging. Cardiac magnetic resonance (CMR) and cardiac computer tomography (CCT) myocardial imaging give us more precise imaging with an improved special resolution which can depict subendocardial ischemia. As for CMR, T2 weighted imaging demonstrated edematous region without enhancement. Recent advances in CMR of parametric mapping technique now permit the visualization and quantification of the tissue characteristics and also give us the opportunity to guess disease process. On the other hand, SPECT fusion imaging with a coronary artery from CCT or CMR also gives us useful territorial information of coronary artery disease. In this chapter, recent advances and status of CMR and CCT imaging surrounding SPECT MPI are described.
