3D Pseudo-Continuous Arterial Spin Labeling is a desirable approach for the measurement of renal perfusion because of its capability of providing noninvasive and non-contrast perfusion imaging. Compared to prior approaches, the 3D PCASL technique exhibits more uniform perfusion images with better SNR and lower SAR. In this work, 3D PCASL technique was successfully implemented in the measurement of kidney perfusion and renal blood flow was calculated. Perfusion weighted images with 2025ms PostLabelDelay time had better CNR and background suppression. Mean renal blood flow of the kidney cortex is about 0.5015 ml/min/g, similar to prior PET results.
