Cardiac MRI (with contrast agent) clinical trials

Impact of Atrial Fibrosis Surface Area on the Occurrence of Atrial Fibrillation in Patients With Ischemic Stroke of Undetermined Origin: a Prospective Cardiac MRI Pilot Study.

This study looks at using heart scans (MRI) after an unexplained stroke. We want to see if these scans can help identify people at higher risk of an irregular heartbeat called atrial fibrillation, potentially guiding who needs a small heart monitor implanted.
