I-123 MIBG Scan

The MIBG is a scan that enables doctors to see any areas where a neuroblastoma or Pheochromocytoma may be.  The patient will come to the hospital for three consecutive days.  The first day the patient will arrive and be given a Potassium iodide solution.  This solution will be diluted and given to the patient to help both the I-123 from entering the thyroid.  On the second day, the patient will be injected with a radiotracer and given a second dose of the Potassium iodide solution.  Finally, on the third day, the patient will be scanned from head to foot and given Potassium iodide solution. 

This test is done over three days.  The first two days are short, but the day of scanning, the last day, takes approximately two hours. 

**If unable to remain still, sedation can be used.  Most often sedation is used.
