Magnetic resonance perfusion (MRP) imaging is a widely used clinical imaging technique to determine how blood flows through biological tissue. Due to the generic nature of MRP, its application extends from the brain and heart to any other organ in the body. The most important application of MRP is to determine if the tissue of interest lacks blood flow. A major focus is on the ischemic stroke, which is a lack of blood in the brain tissue due to blood vessel blockage, and the myocardial ischemia, which is the lack of blood in the heart muscle tissue. This article will discuss MRP for the brain tissue. A detailed description of the challenges is provided next.
