Detection of pseudoaneurysm of the left ventricle by fast imaging employing steady-state acquisition (FIESTA) magnetic resonance imaging.

This report highlights the importance of interpretating images throughout the course of a dobutamine MRI stress test. Upon review of the baseline images, the left ventricular (LV) endocardium was not well seen due to flow artifacts associated with low intracavitary blood-flow velocity resulting from a prior myocardial infarction. Physicians implemented a cine fast imaging employing steady-state acquisition (FIESTA) technique that was not subject to low flow artifact within the LV cavity. With heightened image clarity, physicians unexpectedly identified a LV pseudoaneurysm.
