About MUGA Scan

A MUGA scan, also known as a multigated acquisition scan, is a nuclear medicine imaging examination used to evaluate the pumping function of the heart. It commonly assesses the left ventricular ejection fraction (LVEF), which represents the percentage of blood pumped out of the left ventricle with each heartbeat.

The examination uses a radioactive tracer associated with red blood cells and a gamma camera to capture images of the heart as it beats. The resulting images help clinicians assess ventricular function and cardiac blood-pool activity.

What Does a MUGA Scan Evaluate?

A MUGA scan primarily evaluates the pumping function of the ventricles, particularly the left ventricular ejection fraction. It may also provide information about the movement and function of the heart's ventricular walls.

The findings are interpreted alongside symptoms, medical history, echocardiography and other cardiac investigations.

Why Is a MUGA Scan Recommended?

A doctor may recommend a MUGA scan when an accurate assessment of ventricular function is needed. It may be used in selected patients with known or suspected heart dysfunction and in some patients receiving treatments that may affect cardiac function.

The examination may also be considered when additional information about the left ventricular ejection fraction is required. The treating doctor determines whether the scan is appropriate for the patient's clinical condition.

How Is a MUGA Scan Performed?

A small amount of a prescribed radioactive tracer is administered according to the nuclear medicine protocol. In many protocols, the tracer is attached to the patient's red blood cells so that the blood pool can be imaged.

The patient is positioned near a gamma camera, which records images of the heart over multiple cardiac cycles. Electrocardiographic gating helps coordinate image acquisition with the heartbeat.

The collected images are processed to assess ventricular function and calculate the left ventricular ejection fraction. The exact procedure and duration depend on the prescribed protocol.

Preparation for a MUGA Scan

Preparation requirements depend on the patient's medical condition and the imaging protocol. Follow the instructions provided by the nuclear medicine team.

• Bring the referral and previous cardiac investigation reports, if available.
• Inform the team about current medications and relevant medical conditions.
• Inform the team about pregnancy or possible pregnancy and breastfeeding, where applicable.
• Follow any instructions regarding food, fluids and medication before the examination.
• Tell the team about previous nuclear medicine procedures or relevant blood-related conditions.

Do not stop prescribed medication unless advised by your treating doctor.

Benefits of MUGA Imaging

MUGA imaging provides quantitative information about ventricular pumping function and can help assess the left ventricular ejection fraction. It may be useful when serial measurements of cardiac function are required in selected clinical situations.

The scan provides information about cardiac function but does not independently assess every cause of heart disease or replace all other cardiac investigations.

Understanding the MUGA Scan Report

The report may include the calculated left ventricular ejection fraction and observations about ventricular wall motion or other features visible on the acquired images.

A qualified nuclear medicine physician interprets the results in conjunction with the patient's medical history and other investigations. The treating doctor explains what the findings mean for further evaluation or management.

Frequently Asked Questions

What is a MUGA scan?

A MUGA scan is a nuclear medicine cardiac imaging test used to assess ventricular pumping function and measure the left ventricular ejection fraction.

What does MUGA stand for?

MUGA stands for multigated acquisition. It refers to the technique used to collect cardiac images coordinated with the heartbeat.

Why is a MUGA scan performed?

It may be recommended when doctors need to assess ventricular function or measure the left ventricular ejection fraction in selected patients.

Does a MUGA scan use a gamma camera?

Yes. The examination uses a gamma camera to record images of the heart's blood pool over multiple cardiac cycles.

Does a MUGA scan involve radiation?

Yes. The scan uses a radioactive tracer and involves exposure to ionising radiation. The nuclear medicine team determines the appropriate protocol for the clinical indication.

How long does a MUGA scan take?

The duration varies depending on tracer preparation, image acquisition and the prescribed protocol. Contact the imaging centre for examination-specific timing information.

What is LVEF in a MUGA scan?

LVEF stands for left ventricular ejection fraction. It is the percentage of blood pumped out of the left ventricle with each heartbeat and is one of the main measurements obtained from a MUGA scan.
