I-123 MIBG

A radioactive material will be injected into your body. Pictures are taken at 24 hours and possibly 48 hours following your injection. Prior to the exam and sometimes after your exam, you will be given drops that block the thyroid from absorbing the radioactive material.

You may be asked to stop taking certain medications prior to the study.

An I-123 MIBG scan is used to detect and locate adrenal gland tumors and certain neuroendocrine tumors in the body. This includes conditions such as pheochromocytomas (tumors of the adrenal gland), neuroblastomas (commonly found in children), and paragangliomas. The scan helps physicians determine the location and extent of these tumors.

The I-123 MIBG scan is conducted over multiple days. After receiving the radioactive injection, you’ll return for imaging at 24 hours and possibly again at 48 hours. Each imaging session typically takes 30-60 minutes, but the overall process spans 1-2 days depending on your physician’s requirements.

Yes, the I-123 MIBG radioactive tracer is safe and has been used in medical imaging for many years. The amount of radiation exposure is carefully controlled and is comparable to other nuclear medicine exams. The radioactive material naturally leaves your body over time through normal bodily functions.
