Patienterne skal have passende thyreoideablokerende behandling forud for injektionen for at minimere skjoldbruskkirtelens optagelse af radioaktivt iod, for eksempel ved oral administration af cirka 120 mg kaliumiodid 1 – 4 timer inden injektion og igen 12 – 24 timer efter injektion af DaTSCAN.
2 Patients must undergo appropriate thyroid blocking treatment prior to injection to minimise thyroid uptake of radioactive iodine, for example by oral administration of approximately 120 mg potassium iodide 1-4 hours prior to injection and again 12-24 hours post-injection of DaTSCAN.
