Overview
Cardiovascular MRI is not commonly used for the diagnosis of cardiac tamponade as it is effectively diagnosed based on clinical features and echocardiography.
MRI
- MRI has a limited role in the setting of cardiac tamponade due to the emergent and life-threatening nature of the disease.[1]
- Cardiac tamponade is characterized by the diastolic collapse the right-sided chambers and sometimes the left-sided chambers on cine images.
Findings
- Pericardial effusion
- Distension of the vena cavae and hepatic veins
- Collapse of the right sided cardiac chambers
- Interventricular septum shifts towards the left (paradoxical septal motion)
