Most studies using arterial spin labelling (ASL) for perfusion in the abdomen have used 2D acquisitions in a limited number of slices. We evaluated 3D Fast Spin Echo (3D FSE) imaging for volumetric acquisition of perfusion in the kidneys. In sagittal image volumes over each kidney, isotropic 2.6-mm resolution was achieved allowing assessment in any orientation. Quantitative perfusion values were found to be comparable to a 2D ASL single-shot FSE sequence, and gave values for total renal blood flow that are in broad agreement with physiological values.
