Diagnostic value of cardiac magnetic resonance in occult cardiac embolism

Abstract

Cardiac magnetic resonance (CMR) is widely used in the diagnosis and treatment of cardiac diseases, but its application in the field of ischemic stroke is unclear. As a noninvasive test, CMR plays an important role in clarifying the etiological mechanisms of ischemic stroke and can identify occult cardiac embolism. This article reviews the application of CMR in the diagnosis of occult cardiac embolism, the identification of potential etiologies of ischemic stroke such as cardiac thrombus, left atrial enlargement, left atrial fibrosis, left auricular morphology and rare cardiomyopathies, as well as advantages and disadvantages of CMR, which will in turn provide a reference for the early identification of occult cardiac embolism in the clinic.
