The potential of non-contrast enhanced renal angiography at 7T was explored. In order to obtain consistent bilateral visualization of the renal arteries transmit B1 homogeneity was optimized using a subject dependent, three slice, small flip angle calibration scan acquired in a single breathold. High quality visulizaiton of proximal and distal renal arteries was obtained despite system limits on achievable transmit B1.
