Key result
3D MRI detected more complex aortic plaques than TEE in the ascending aorta (13 vs 7) and aortic arch (37 vs 11), revealing additional plaques in 32.8% of cryptogenic stroke patients.
Why the study?
Does 3D MRI improve the detection of complex aortic plaques compared to TEE in patients with acute cryptogenic stroke?
Observational (n=99)
Does 3D MRI improve the detection of complex aortic plaques compared to TEE in patients with acute cryptogenic stroke?
3D MRI provides superior visualization and detection of complex aortic plaques in the proximal aorta compared to TEE, identifying potential stroke etiologies in nearly a third of patients previously deemed cryptogenic.

3D MRI may serve as a noninvasive alternative to TEE for complex aortic plaque detection; leaves open its clinical adoption pending validation.
Harloff et al. (2012) conducted an observational in Acute cryptogenic stroke (n=99). 3D magnetic resonance imaging (3D MRI) vs. Transesophageal echocardiography (TEE) was evaluated on Detection of complex aortic plaques (≥4 mm thick, ulcerated, or containing mobile thrombi). 3D MRI detected more complex aortic plaques than TEE in the ascending aorta (13 vs 7) and aortic arch (37 vs 11), revealing additional plaques in 32.8% of cryptogenic stroke patients.
