Perfusion weighted imaging is a term used to denote a variety of MRI techniques able to give insights into the perfusion of tissues by blood.
There are three techniques in wide use to derive one or more perfusion values:
-
techniques
-
derived values
The main role of perfusion imaging is in evaluation of ischemic conditions (e.g. acute cerebral infarction to determine ischemic penumbra, moyamoya disease to identify vascular reserve), neoplasms (e.g. identify highest grade component of diffuse astrocytomas, help distinguish glioblastomas from cerebral metastases) and neurodegenerative diseases.
