Rest/Stress Myocardial Perfusion Imaging by Positron ...
· Background Myocardial perfusion imaging by positron emission tomography (PET-MPI) is the current gold standard for quantification of myocardial blood flow. 18 F-flurpiridaz was recently introduced as a valid alternative to currently used PET-MPI probes. Nonetheless, optimum scan duration and time interval for image analysis are currently unknown. Further, it is unclear whether rest/stress PET ...

Myocardial Perfusion - Cardiac MRI
Myocardial Perfusion. Assessing Perfusion Defects. ... In abnormal (affected, ischemic) tissue, myocardial perfusion also may not be altered under rest conditions, due to coronary flow reserve. Arteriolar vasodilation compensates to increase the blood flow despite the blockage, enabling the tissue to receive an adequate supply of oxygen. (It is ...

Resting Myocardial Perfusion Scan | Northwestern Medicine
· Myocardial perfusion is an imaging test. It's also called a nuclear stress test. It is done to show how well blood flows through the heart muscle. It also shows how well the heart muscle is pumping. For example, after a heart attack, it may be done to find areas of damaged heart muscle. This test may be done during rest and while you exercise.
