AJR Am J Roentgenol. 2011 Jan;196(1):53-60. doi: 10.2214/AJR.10.5705.


Objective: The objective of this article is to address the 10 most frequently asked questions radiologists face when planning, performing, processing, and interpreting a perfusion CT study in a patient with clinical suspicion of acute ischemic stroke.

Conclusion: It is important for radiologists using PCT for stroke imaging to be familiar with the perfusion software used at their institution, with the parameters that can be selected during the post-processing and how these may influence the PCT results.
