Multigated Acquisition Scan

Multigated Acquisition Scan

We often rely on advanced tools and technologies to uncover the hidden truths of the human body. One such diagnostic tool in understanding our heart's inner workings is the Multi-Gated Acquisition (MUGA) scan. Specifically designed to assess the function and health of the heart's ventricles, a MUGA scan helps ensure optimal cardiac function and minimize perioperative risks.

The Science Behind MUGA Scan

At the heart of a MUGA scan lies the fusion of nuclear medicine and imaging technology. The procedure involves introducing a minute quantity of a radioactive tracer, often technetium-99m labeled red blood cells or an alternative tracer, into the patient's bloodstream. This tracer, with its affinity for red blood cells, embarks on a journey through the circulatory system, and to the heart.
As the radioactive tracer circulates through the cardiovascular system, a sophisticated gamma camera comes into play. Positioned strategically over the patient's chest, this camera detects gamma rays emitted by the tracer-bound red blood cells. What ensues is a fusion of technology and biology to capture the heart's dynamic pumping action with remarkable precision.

The MUGA Scan’s Objective

The primary objective of a MUGA scan is to unlock insights into the heart's ventricular function, particularly focusing on the left ventricle – which is the powerhouse responsible for pumping oxygen-rich blood throughout the body. 
Through a synchronized data acquisition process, (synchronized with the patient's heartbeat via electrocardiogram (ECG) signals), the gamma camera captures a series of images representing different phases of the cardiac cycle. One of the key metrics derived from these images is the ejection fraction, a fundamental indicator of the heart's efficiency in pumping blood. A normal ejection fraction typically falls within the range of 50% to 70%, reflecting a healthy and robust cardiovascular system. 
Deviations from this range may indicate underlying cardiac issues that warrant further investigation and management.

When is the MUGA Scan Utilized?

The clinical utility of MUGA scans extends across various domains within cardiology and cardiovascular care. In addition to providing precise measurements of the ejection fraction, the MUGA scans also

  • offer insights into wall motion abnormalities, contractility patterns, and overall ventricular function, crucial for comprehensive cardiac assessment,
  • serve as valuable tools for monitoring treatment response over time, thereby guiding therapeutic interventions, and optimizing patient outcomes, and
  • play a vital role in preoperative cardiac clearance, helping ensure optimal cardiac function and minimizing perioperative risks.

Considerations and Patient Experience

While MUGA scans involve the use of a radioactive tracer, the associated radiation exposure is typically minimal and well within safe limits. Our patients undergoing a MUGA scan will receive specific instructions regarding fasting, caffeine avoidance, and other preparatory measures to optimize imaging quality and safety.
Before the procedure, we will review your medical history as well as details about  any previous heart-related issues, current medications, allergies, lifestyle factors, and family history of cardiovascular diseases. At Capitol Cardiology Associates, we are proud to address questions and concerns, and we encourage you to call or visit us to schedule a consultation.

Review of Exceptional Healthcare Services

Jose Mendoza

My experience with the Capitol Cardiology Associates office was outstanding. From the time I initially talked to Dr Shetty on the phone to the moment I checked out. I had a very pleasant encounter with the front desk personnel. The staff is kind, gentle and informative. Pamela was very efficient, skilled and smart.  Took time to explain the procedure and broke it down in easy terms. I recommend this group with no reservations to whoever needs a cardiologist.

Bobbie Shockley

Even the office was excited busy, the staff remains super courteous and respectful. Dr. Shetty and his students were kind and efficient. Check out is a breeze. Those with disabilities were treated with great respect. I feel well cared for here at Capitol  Cardiology.

Jeanette McQueen

I had an excellent experience at Capitol Cardiology Associates. From the moment I walked into the suite everyone was friendly and courteous. When I was taken in the back the Medical Assistant was very professional and made me feel comfortable. My Cardiologist, Dr. Venugopal, had an excellent bedside manner and reassured me that all was okay. The checkout receptionist was very helpful as well. She made sure I had all the documents I needed and provided a copy to my primary care physician. Well done guys!??

Kuron Rice

On my first visit to Capitol Cardiology Associates, the staff were punctual, professional & friendly.  I enjoyed every aspect of the visit. The lady who checks you in has high energy & is very fun. My nurse was very nice as well. But my doctor, Dr. Foushee was attentive to symptoms & asked lots of question to find out the problem & it's source. For top notch service visit Capitol Cardiology Associates!!!

Bonnie Moreland

Everyone that I had contact with in the office were so pleasant. I feel Claire, PA listened to me about my concerns. She assured me that tests will be done and we'll figure out what's going on and that I'll be feeling better soon.

James Churchill

This was my first visit to a specialist, Dr. Venugopal. While the appointment took time to get, I was greeted promptly, the staff treated me well both coming in and leaving and the doctor is one of the finest I've encountered. Not only was he informative, his professional demeanor was complemented by a a humor that matched my own, a talent not always found in potentially serious situations. I would highly recommend!

J D McCall

Dr. Forrester is very professional, competent, thorough and caring. He is thoughtful, knowledgeable & attentive.The staff are very kind, professional & attentive as well. Overall excellent place to go.

I have had positive experience with the staff of Capital Cardiology. They are courteous, professional and efficient. Dr. Clarence Findley is fabulous. He takes his time explaining , asking questions etc. Not something one sees now a days.

Rhonda McNair

I really was sick not knowing just how sick. My PC referred me to Dr. Clarence Fendly with only three visits two office and one hospital I am great. I thank God for him. He explained everything to me where I could understand,  but he's gone now, and I am going to miss him. I feel sorry for all on this side of the earth that never had the opportunity to get his help. Where ever he's moved on to someone will be blessed. Thanks Dr. Fendley. Rhonda McNair
