About MIBG Scan

MIBG imaging is a nuclear medicine examination that uses a radiolabelled compound called metaiodobenzylguanidine (MIBG) to evaluate selected conditions involving tissues that take up this tracer. Depending on the clinical indication, the study may use iodine-123 or iodine-131 labelled MIBG.

Images are acquired using a gamma camera to assess the distribution of the radiotracer in the body. The tracer, imaging schedule and protocol depend on the condition being investigated and the nuclear medicine team's instructions.

What Does an MIBG Scan Evaluate?

MIBG imaging can help identify tissues that take up the tracer and may be useful in evaluating selected neuroendocrine tumours, including pheochromocytoma and paraganglioma. Certain other conditions may also be investigated with MIBG imaging when clinically indicated.

The findings are interpreted alongside symptoms, laboratory results, medical history and other imaging investigations.

Why Is an MIBG Scan Recommended?

A doctor may recommend an MIBG scan when evaluating a suspected or known MIBG-avid tumour or when additional information about the distribution of disease is needed. The examination may be used for localisation, disease assessment or follow-up in selected patients.

The clinical purpose depends on the prescribed tracer and the referring specialist's assessment. Not every neuroendocrine tumour takes up MIBG, so the suitability of the scan must be determined clinically.

How Is an MIBG Scan Performed?

The prescribed radiotracer is administered according to the nuclear medicine protocol. Images are acquired using a gamma camera at specified intervals after administration. Some protocols require delayed imaging or additional views.

The imaging team provides instructions about positioning, the imaging schedule and any additional procedures required. The duration and number of visits depend on the tracer and clinical indication.

Preparation for an MIBG Scan

Preparation requirements vary according to the tracer and the patient's medical condition. Some protocols require specific medication precautions or thyroid-blocking medication to reduce thyroid uptake of free radioiodine.

• Inform the nuclear medicine team about all medications, supplements and existing medical conditions.
• Do not stop medicines unless specifically instructed by the treating doctor or nuclear medicine team.
• Inform the team about pregnancy or possible pregnancy and breastfeeding, where applicable.
• Bring relevant laboratory reports, previous scans and the referring doctor's notes.
• Follow the centre's instructions regarding food, fluids, medications and the imaging schedule.

Benefits of MIBG Imaging

MIBG imaging provides functional information about the distribution of a specific radiotracer in tissues that take it up. It can support the evaluation of selected neuroendocrine and adrenal conditions when the tumour or tissue is suitable for this type of imaging.

The usefulness of the examination depends on tracer uptake, the clinical indication and correlation with other investigations. The scan does not replace a complete clinical assessment.

Understanding the MIBG Scan Report

The report may describe the distribution and intensity of radiotracer uptake and identify areas requiring further evaluation. The significance of these findings depends on the tracer used, the imaging protocol and the patient's clinical history.

A qualified nuclear medicine physician interprets the images alongside laboratory findings and other investigations. The treating specialist explains the results and their implications for further evaluation or management.

Frequently Asked Questions

What is an MIBG scan?

An MIBG scan is a nuclear medicine imaging examination that uses radiolabelled metaiodobenzylguanidine to evaluate selected conditions involving tissues that take up the tracer.

What does MIBG stand for?

MIBG stands for metaiodobenzylguanidine, a compound used in nuclear medicine imaging and certain specialised therapeutic applications.

Why is an MIBG scan performed?

It may be recommended to evaluate selected neuroendocrine tumours, including pheochromocytoma and paraganglioma, when MIBG imaging is clinically appropriate.

Does an MIBG scan use a gamma camera?

Yes. Diagnostic MIBG scintigraphy generally uses a gamma camera to detect radiation from the administered radiotracer and create images.

Does an MIBG scan involve radiation?

Yes. The examination uses a radioactive tracer and involves exposure to ionising radiation. The tracer and protocol are selected according to the clinical indication.

Is preparation required before an MIBG scan?

Yes. Preparation may include medication review and other tracer-specific instructions. Follow the guidance provided by the nuclear medicine team.

How long does an MIBG scan take?

The duration depends on the tracer and imaging protocol. Some examinations require delayed images or imaging over more than one day. Confirm the schedule with the centre before your appointment.
