The procedure

You will receive an intravenous injection of a small amount of a radioactive tracer called 131I MIBG.

Two days later, your entire body will be imaged to determine the distribution of the tracer. It will take approximately one hour.

The physicians may request that you return for an image on the third day. They may also ask for a correlative image of the kidneys with injection of a renal tracer to localize them in relation to the adrenal glands to aid in your diagnosis.

After Care
