Y1 - 2011 N1 - T2 - Multimodal Cardiovascular Imaging: Principles and Clinical Applications AB - Myocardial perfusion single photon emission computed tomography (SPECT) is a nuclear medicine imaging technique that uses a radioactive perfusion tracer to detect ischemia. Myocardial SPECT can detect, localize, and quantify the degree of ischemic myocardium. The result of a myocardial perfusion SPECT is related to the prognostic outcome of cardiac events (ie, myocardial infarction and death). Therefore, myocardial perfusion SPECT is used to guide treatment in patients with stable angina and after acute coronary syndrome. Myocardial perfusion SPECT is a mature technique, one of the most commonly used cardiac imaging techniques, and part of the international guidelines for treatment of patients with ischemic heart disease.1-3 There are international guidelines on how to perform,4 how to report,5 and when to use6 myocardial perfusion SPECT. Myocardial positron emission tomography (PET) is a newer nuclear medicine imaging technique that has rapidly become routine in cancer patients. The use in cardiology is also increasing because PET has inherent advantages compared to SPECT (eg, better image resolution and the possibility for absolute quantification of blood flow). However, the limited availability of the technique and especially of the PET perfusion tracers and higher costs are influencing the choice of method, and SPECT has kept its role as the main workhorse for cardiac patients.
