Perfusion Magnetic Resonance Imaging

**Definition:** A specialized type of MRI technique that provides information about HEMODYNAMIC parameters such as CEREBRAL BLOOD VOLUME, CEREBRAL BLOOD FLOW, and transit time. In perfusion MRI, an exogenous CONTRAST AGENT is usually injected to provide superior tissue contrast and easy delineation of perfusion abnormalities. Endogenous markers can also be used.
