Dialysis patients had 3 times the signal increase on unenhanced T1-weighted images compared to a control population with near normal renal function undergoing the identical number of GBCA administrations. Although any clinical consequence to GBCA administration would be expected to be magnified in dialysis patients, no clinical effect of receiving GBCA could be identified in the nephrologist/nursing notes recorded 3 times a week in the 30 days following GBCA administration.
