AIM: We sought to determine whether the presence of contrast agent affects PC-CMR measurements of aortic blood flow, and myocardial displacement of the left ventricle in humans. METHODS: Velocity-encoded data was acquired pre and post contrast agent administration. RESULTS: Cardiac output differed -0.040.52 l/min and myocardial displacement 0.10.5mm. Magnitude image contrast for myocardial displacement was visually lower in the post contrast agent images. CONCLUSIONS: Acquisition of aortic flow is feasible both in the absence and presence of contrast agent. For myocardial displacement phase-contrast data is assessable as such, but delineation not possible post contrast agent administration due to lower image contrast.
