MR perfusion 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:


  • Dynamic susceptibility contrast (DSC) MR perfusion.
  • Dynamic contrast enhanced (DCE) MR perfusion.
  • Arterial spin labelling (ASL) MR perfusion.

Derived values

  • Time to peak (TTP)
  • Tean transit time (MTT)
  • Cerebral blood volume (CBV)
  • Cerebral blood flow (CBF)
  • Negative enhancement integral (NEI)
  • k-trans

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.
