Dynamic imaging of the kidneys using MR offers non-invasive information about the renal anatomy and function. However, despite many improvements in renal MRA, there is a need for higher temporal resolution in time-resolved MRA, while minimizing the risks associated with gadolinium based contrast agents. In this study, low-dose renal MRA was performed using the previously developed CAMERA technique to achieve higher temporal resolution without undersampling.
