Abstract
Introduction Ischemic evaluation of the left ventricle (LV) by MR imaging can be performed using a combination of rest and stress images during a bolus contrast injection. Additionally, late-gadolinium-enhanced images are used determine the presence and extent of infarction. Myocardial tissue composition and vascular status may be determinants of myocardial blood flow in the resting and stress states. The effects of fibrosis as well as fat deposition on MR first-pass perfusion images have not been well studied. LV fat deposition is easily detected with MR imaging and is associated with chronic LV myocardial infarction, with a prevalence of approximately 60%. Assessment of perfusion in myocardial segments with fibrosis is clinically relevant for the determination of peri-infarct ischemia.

Ischemic evaluation of the left ventricle (LV) by MR imaging can be performed using a combination of rest and stress images during a bolus contrast injection
LV fat deposition is detected with MR imaging and is associated with chronic LV myocardial infarction, with a prevalence of approximately 60%
In patients with LV chronic myocardial infarction, resting perfusion defects are rare in the absence of fat deposition
