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.

to five days after the injection.
