In this issue of the AJNR News Digest, we highlight considerations regarding the use of CT perfusion (CTP) imaging for acute neurovascular assessment.

Although the idea of measuring cerebral perfusion by tracking a contrast bolus with rapid sequence imaging has been … more »

Jerrold L. Boxerman

This paper explored whether CT perfusion (CTP) imaging significantly affected our decision to administer intra-arterial therapy (IAT) in patients with acute stroke beyond the information from noncontrast CT (NCCT), CT angiography (CTA), and the NIH Stroke Scale (NIHSS). This was … more »

Patient-Tailored Perfusion Thresholds and Multimodal CT

Richard Aviv

Richard I. Aviv

Since its inception, I have been convinced of the extraordinary potential of CT perfusion imaging in acute stroke to improve upon the landmark NINDS and ECASS stroke studies that used noncontrast CT alone to define a target population for stroke thrombolysis. It … more »
