Cardiac MRI in Ischemic Stroke Study

Cardiac MRI in Ischemic Stroke Study

The purpose of this prospective single-center trial is to compare the safety and diagnostic value of contrast medium-enhanced cardiac magnetic resonance imaging and transesophageal echocardiography in patients with acute ischemic stroke.

Primary safety objective: Contrast medium-enhanced cardiac magnetic resonance imaging is safe in patients with acute ischemic stroke. Primary outcome: The diagnostic value of contrast medium-enhanced cardiac magnetic resonance imaging is comparable to transesophageal echocardiography in patients with acute ischemic stroke.

Inclusion Criteria:

• Patients with acute ischemic stroke detected by brain magnetic resonance imaging.

Exclusion Criteria:

• Known atrial fibrillation or cardiac source of embolism
• Severe aphasia
• Acute infection or chronic inflammation
• Severe arteriosclerosis or stenosis of brain-supplying arteries
• Contraindications for magnetic resonance imaging or transesophageal echocardiography.
