MRI Perfusion (MRI)
Understanding MRI Perfusion (MRI)
What is MRI Perfusion (MRI)?
An MRI Perfusion helps assess a wide range of abnormalities of the brain, including tumours, growths, infections, and vascular and degenerative diseases. It assists in grading and assessing tumours and treatment guidance and evaluation of treatment response in both stroke and cancer patients.
Perfusion refers to fluid transfer from the lymphatic system or blood vessels to an organ or tissue. Perfusion information obtained from MRI can be used to calculate tissue properties related to blood flow.
The MRI Perfusion method is widely available and relatively easy to use. Usually, the test takes 30 to 60 minutes to complete, but it can take up to 2 hours. MR perfusion imaging requires IV infusion of a gadolinium-based contrast agent at a relatively rapid injection rate.
What is MRI Perfusion (MRI) used for?
- To diagnose ischaemic condition like cerebral infarction (dead brain tissue which results from the narrowed or blocked arteries supplying blood and oxygen to the brain
- To find out area of the brain damaged due to lack of blood supply
- To detect moya moya disease (blocked brain arteries)
