What is the strength of combined imaging?
The strength of combined imaging is the added value of anatomy guiding interpretation of ischemic and scarred myocardium as well as providing information to guide therapeutic decision making. Hybrid imaging also can overcome technical limitations of myocardial perfusion SPECT or myocardial perfusion PET by providing anatomic correlates to guide interpretative accuracy207 and can provide the functional information that an anatomic technique like CCTA or magnetic resonance angiography lacks; however, radiation dose is increased.
