NCT ID: NCT03250455 Recruiting - CT Perfusion Clinical Trials

Prognostic Value of CT dynamIc Myocardial Perfusion in Patients With Obstructive Coronary Artery Stenosis

VALIDITY
Start date: August 2017
Phase: N/A
Study type: Observational [Patient Registry]

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.

NCT ID: NCT02056769 Active, not recruiting - Clinical trials for Subarachnoid Hemorrhage

CT Perfusion Imaging to Predict Vasospasm in Subarachnoid Hemorrhage

CT-PIPS
Start date: April 2014
Phase: N/A
Study type: Interventional

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.
