Acute myocardial infarction can be incidentally detected using T2-weighted and post-gadolinium 3D gradient echo MRI, with findings correlating well with autopsy.
May aid incidental acute MI detection on MRI; case report leaves open prospective validation before practice change.
We report on the MR appearance of acute myocardial infarction in a 61-year-old man with Ehlers-Danlos syndrome using motion-independent, T2-weighted echo train spin echo and immediate post-gadolinium three-dimensional gradient echo imaging performed as an MRI angiographic study of the aortic arch. The region of acute infarction was of high signal intensity on the T2-weighted images and demonstrated greatly diminished enhancement on the immediate post-gadolinium three-dimensional gradient echo images. MRI findings showed good correlation with autopsy specimens obtained within 24 hours of the MRI study.
