MR perfusion weighted imaging

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: 

The main role of perfusion imaging is in evaluation of ischaemic conditions (e.g. acute cerebral infarction to determine ischaemic 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.
