An ASL-FAIR technique was optimized to measure cortical perfusion in native and transplanted kidneys. Motion compensation methods, kidney-specific T1 information, and a measured FAIR inversion factor are incorporated into perfusion measurement and calculation. Perfusion results with and without corrections are shown for two subjects (one transplant and one native) with diminished kidney function. Correction based methods are shown to affect the perfusion results by as much as 39%.
