How long until i know i did not developed nsf from gadolinium contrast, i read it takes time to develop? thanks

NSF : If you only had a single MRI then the risk is virtually zero. And if you are more than 24 hours from the gadolinium, i wouldn't waste another minute worrying.

NSF : Nsf has not been reported in patients without significant kidney disease, and most of those individuals were already on dialysis. If you are not a dialysis patient, you should not worry about nsf.
