Renal BOLD MRI. Blood oxygen level-dependent (BOLD) MRI in the cortex and the medulla of the contra-lateral (left) and stenotic (right) kidneys, at baseline and 2 and 4 weeks later in RAS and control mice (A-D). Dash-lines show the mean R2* in control animals over the entire course of study (*p < 0.05 vs. baseline RAS, $p < 0.05 vs. baseline Control, #p < 0.05 vs. control and †p < 0.05 vs. 2-weeks RAS). BOLD maps acquired using the conventional (E) and the improved (F) BOLD techniques. Severe abdominal susceptibility artefact is evident in the conventional BOLD map.
