Rest Myocardial Viability SPECT in Chennai
Rest Myocardial Viability SPECT is a nuclear medicine imaging procedure used to assess the viability of heart muscle tissue that has been damaged due to coronary artery disease (CAD) or previous heart attacks. It evaluates whether the damaged tissue is still capable of functioning or if it has become scar tissue.
What is the need for the study?
The Rest Myocardial Viability SPECT study is performed to:
- Determine the extent of viable (functioning) versus non-viable (scarred) myocardial tissue in patients with CAD or a history of heart attacks.
- Assess the potential benefit of revascularization procedures, such as angioplasty or coronary artery bypass grafting (CABG), in improving heart function and reducing symptoms.
- Guide treatment decisions and optimize management strategies for patients with ischemic heart disease.
This study helps healthcare providers identify viable myocardium that may benefit from interventions aimed at restoring blood flow and improving cardiac function.
How do I prepare?
Preparation for a Rest Myocardial Viability SPECT study may include:
- Medication: Inform your healthcare provider about any medications you are taking, as certain medications may need to be temporarily stopped before the study.
- Fasting: You may be instructed to fast for a period before the study, typically for several hours, to ensure an empty stomach for accurate imaging.
- Avoiding Caffeine: Avoid consuming caffeinated products, such as coffee, tea, and chocolate, for a specified period before the study, as caffeine can interfere with the results.
- Clothing: Wear comfortable clothing and appropriate footwear for the scan.
Your healthcare provider will provide specific instructions on how to prepare for the Rest Myocardial Viability SPECT study based on your individual circumstances.
How is this scan performed?
During a Rest Myocardial Viability SPECT study:
- Radiotracer Injection: A radioactive tracer, such as technetium-99m (Tc-99m) sestamibi or tetrofosmin, is injected into a vein at rest.
- Imaging: A gamma camera is used to acquire images of the heart from various angles while you are at rest. The radioactive tracer emits gamma rays that are detected by the camera, allowing visualization of myocardial perfusion and identification of viable and non-viable myocardial tissue.
- Data Analysis: The images obtained from the scan are analyzed by a nuclear medicine technologist or radiologist to assess myocardial viability, identify areas of scar tissue, and determine the extent of viable myocardium.
What should I do after the scan?
After the Rest Myocardial Viability SPECT scan:
- Resume Normal Activities: You can usually resume your normal activities immediately after the scan.
- Follow-Up: Attend any scheduled follow-up appointments with your healthcare provider to review the results of the study and discuss further management, if necessary.
Are there any risks in the study?
Rest Myocardial Viability SPECT is generally considered safe and non-invasive. The amount of radiation exposure from the radioactive tracer used in the study is minimal and poses little risk to
most patients. However, just like any radiation-related medical procedure, there is a slight chances of allergic reactions or adverse effects.
Your healthcare provider will discuss the potential risks and benefits of the Rest Myocardial Viability SPECT study with you and address any concerns you may have before proceeding with the procedure.
It’s essential to follow all instructions provided by your healthcare provider and communicate any symptoms or concerns you experience during or after the Rest Myocardial Viability SPECT study. Your healthcare team is here to support you throughout the process and ensure the best possible outcomes for your cardiovascular health.
