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.
