Responses to the 10 most frequently asked questions about perfusion CT.

Abstract

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. 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.
