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:
- derived values
The main role of perfusion imaging is in evaluation of ischemic conditions (e.g. acute cerebral infarction to determine ischemic penumbra, moya-moya disease to identify vascular reserve), neoplasms (e.g. identify highest grade component of diffuse astrocytomas, help distinguish glioblastomas from cerebral metastases) and neurodegenerative diseases.
