Patienten bør opmuntres til at indtage (eller ved intravenøs indgivelse at modtage) mindst 500 ml væske inden injektionen, og patienten bør opmuntres til at tømme blæren så ofte som muligt efter injektionen for at mindske bestråling af blæren.
The patient should be encouraged to ingest (or receive by intravenous administration) a minimum of 500 ml of fluids prior to injection and should be encouraged to void as often as possible after injection to minimise radiation exposure to the bladder.
