Abstract
Ferumoxytole-enhanced 4D MR angiography with retrospectively defined temporal resolution
Highlights
In cardiovascular MRI applications, high spatial resolution is preferable for anatomical evaluation of vascular structures and high temporal resolution is desired in cardiac functional assessment
We propose a technique that allows for retrospective trade-off between temporal and spatial resolution based on a single image acquisition
Major vessels and cardiac structures are clearly defined in these high spatial resolution images
Summary
In cardiovascular MRI applications, high spatial resolution is preferable for anatomical evaluation of vascular structures and high temporal resolution is desired in cardiac functional assessment. Current CMR protocol usually includes repeated scans of the same anatomy with different resolution settings. To address this issue, we propose a technique that allows for retrospective trade-off between temporal and spatial resolution based on a single image acquisition. The proposed technique is applied on Ferumoxytol-enhanced 4D angiography application so that images with high temporal and high spatial resolution are available from separated reconstructions
