I-123 MIBG
* Inform your physician if you are pregnant or breast feeding.
You have been scheduled for an I-123 MIBG study which involves the use of a small amount of radioactive material. The level of radioactivity used is extremely low and has no side effects.
You will be positioned on an imaging table, under a special detector called a gamma camera. The camera does not produce any radiation. It will be placed close to the part of your body being imaged. You may also receive a CT scan as part of the imaging procedure to aid the physicians in interpreting your scan.
Patient Preparation
You must take one (1) drop of SSKI (super saturated potassium iodine) or Lugol’s solution three (3) times a day starting 1 day before and continuing for 3 days after the injection. This is used to keep your thyroid gland from taking up any radioactive material. Your doctor will give you a prescription that may be filled at a pharmacy.
Notify your ordering physician if you are taking any of the following medications as they will interfere with the test:
Labetolol, Reserpine, Calcium channel blockers, Tricyclic antidepressants, Decongestants (over the counter, such as pseudoephedrine, Phenylpropanolamine, and phenylephrine) and Cocaine.
Procedure
This is a 3 part study: on your first visit, a small amount of radioactive material will be injected into your vein. On your second visit (24 hours or the next day), painless images will be obtained for approximately one hour. Your third visit (48 hours), delayed imaging will be obtained for approximately one hour.
