A new quantitative PET method that measures myocardial blood flow may spot evidence of multivessel heart disease missed with standard myocardial perfusion imaging using PET, according to a study presented at ASNC2013. "Stress myocardial blood flow could form the basis of a risk prediction score beyond visual myocardial perfusion imaging, which could then be integrated along with other adjunct markers into clinical software for detection of multivessel coronary artery disease," said Cleveland Clinic researcher Dr. Jun-Yang Lou.
