Influence of motion correction on the visual analysis of cardiac magnetic resonance stress perfusion imaging.

Objective: Image post-processing corrects for cardiac and respiratory motion (MoCo) during cardiovascular magnetic resonance (CMR) stress perfusion. The study analyzed its influence on visual image evaluation.

Materials And Methods: Sixty-two patients with (suspected) coronary artery disease underwent a standard CMR stress perfusion exam during free-breathing.

Influence of contrast agent and spatial resolution on myocardial strain results using feature tracking MRI.

Objectives: Feature tracking for assessing myocardial strain from cardiac magnetic resonance (CMR) cine images detects myocardial deformation abnormalities with prognostic implication, e.g., in myocardial infarction and cardiomyopathy.
