ABSTRACT:
A magnetic resonance imaging method of in-vivo measurement for renal hemodynamic functions by obtaining renal function images in the presence of an intravascular contrast agent with a modified inversion recovery pulse sequence imaging technique, determining the renal artery and renal vein blood longitudinal relaxation times from the data derived from the images and employing these times to arrive at the filtration fraction.
