Apr 2, 2020 · Learn about the MRI techniques and values used to assess tissue perfusion by blood. Find out the main applications of perfusion imaging in neurology, oncology and neurodegeneration.
Perfusion MRI is a promising tool in assessing stroke, brain tumors, and neurodegenerative diseases. Most of the impediments that have limited the use of perfusion MRI can be overcome to allow integration of these methods into modern neuroimaging protocols. Keywords: CNS imaging, contrast agents, gadobutrol, perfusion MRI.

Perfusion MRI or perfusion-weighted imaging (PWI) is perfusion scanning by the use of a particular MRI sequence [which? The acquired data are then post-processed to obtain perfusion maps with different parameters, such as BV (blood volume), BF (blood flow), MTT (mean transit time) and TTP (time to peak).

Learn about brain perfusion scan, a test that shows the amount of blood flow in different areas of your brain. Find out why you might need it, how to prepare, and what to expect during and after the scan.
For MRI perfusion imaging, gadolinium-based compounds are considered nondiffusible, whereas techniques such as arterial spin labeling (ASL)—that use the native protons in blood water—are considered diffusible. PERFUSION IMAGING WITH GADOLINIUM. Overview.
