Perfusion MRI: the five most frequently asked technical questions

AJR Am J Roentgenol. 2013 Jan;200(1):24-34. doi: 10.2214/AJR.12.9543.


Objective: This and its companion article address the 10 most frequently asked questions that radiologists face when planning, performing, processing, and interpreting different MR perfusion studies in CNS imaging.

Conclusion: Perfusion MRI is a promising tool in assessing stroke, brain tumors, and patients with 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.
