Incidental Myocardial Infarct on Conventional Nongated CT: A Review of the Spectrum of Findings With Gated CT and Cardiac MRI Correlation

OBJECTIVES: Myocardial infarctions (MIs) are frequently evident on routine chest or abdominal CT, even when studies are not performed for cardiac-specific indications. However, the telltale signs of an MI may be easily overlooked. Herein, we present the spectrum of appearances of MIs, including areas of fat attenuation, myocardial calcifications, focal areas of wall thinning or aneurysm formation, and perfusion abnormalities. Thrombi, especially when present at the apex of the left ventricle, may also suggest an MI.

CONCLUSIONS: The increased use of CT in the evaluation of patients for a variety of indications gives the radiologist the unique opportunity to recognize findings consistent with MI in patients who may not have a prior diagnosis of ischemic heart disease. Isaiah Wynn Authentic Jersey

  1. This is an important paper for all general radiologists! These are findings that we commonly see on CT examinations of the chest that may have clinical significance. Furthermore it tells your referring clinicians that you are looking for clues to underlying heart disease and many of them may be surprised to read in your report that you were able to tell of the presence of a prior MI.

  2. Excellent review! Isolated papillary muscle calcification (not mentioned in the text) is an incredibly common finding related to CAD we see on non-gated chest CT. As the temporal resolution of all scanners improves, we will be seeing more and more of these findings….
