For two days before and ten days after the injection of the radiopharmaceutical, patients are given either Lugol's solution or potassium iodine. This prevents the thyroid from taking up radioactive iodine and interfering with the scan
a nuclear medicine evaluation of the medulla (inner tissue) of the adrenal gland.
Very simply, the pituitary is considered the master gland because it sends instruction to other glands to produce their hormones. One of those is ACH, or adrenocorticotropic hormone. The pituitary sends it to the adrenal gland so it makes its hormones.
An abnormal adrenal scan may show evidence of a tumor where there is excessive secretion of adrenaline or noradrenaline. Over 90% of these tumors are in the abdomen.
should not feel any adverse effects of the test and can resume normal activity immediately. Follow-up tests that might be ordered include a nuclear scan of the bones or kidney, a computed tomography scan (CT) of the adrenals
when too much adrenaline and noradrenaline is produced in the body and a tumor in the adrenal gland is suspected. One such situation in which a tumor might be suspected is when high blood pressure (hypertension ) does not respond to medication
takes several days. On the first day, a radiopharmaceutical is injected intravenously into the patient. On the second, third, and fourth day the patient is positioned under the camera for imaging. The scanning time each day takes approximately 30 minutes
A salivary gland scan, also called a parotid gland scan
Two to three hours before the scan, technetium is injected into a vein in the patient's forearm.

Because he has a small pituitary gland
A nuclear medicine technologist withdraws about 50 ml. of blood. White blood cells are collected, exposed to indium, and reinjected by IV back into the patient. The scan is scheduled for between 18 and 24 hours after.
