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.
Condition or disease
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.
Sensitivity and specificity of contrast medium-enhanced cardiac magnetic resonance imaging to detect echocardiography-proven cardiac sources of embolism in patients with acute ischemic stroke. [ Time Frame: < 1 week after ischemic stroke ]
Secondary Outcome Measures :
Rate of unrecognised myocardial infarction detected by late gadolinium-enhanced cardiac MRI in patients with acute ischemic stroke. [ Time Frame: < 1 week after ischemic stroke ]
