View clinical trials related to CT Perfusion.
Filter by:VALIDITY is a prospective, open-label, multicenter, randomized controlled trial (ClinicalTrials.gov number). The study was designed to evaluate the value of noninvasive anatomic CTA combined with functional CTP for the next clinical decision making and the added prognostic value of CTP beyond CTA.
Patients with brain hemorrhage resulting from a ruptured aneurysm (SAH) are at risk of developing a condition called vasospasm, one or two weeks after their hemorrhage. This is a major cause of stroke and death following SAH. A special type of CT scan, called CT perfusion, analyzes regional blood flow in the brain. We hypothesize that CT perfusion scans performed on admission and day 6 post-hemorrhage will enable us to predict which patients will go on to develop vasospasm.
