Cardiac PET/CT is a specialized imaging test that evaluates blood flow and heart function. It uses a small amount of radioactive tracer to capture detailed images of your heart in both resting and stress phases.

Unlike traditional stress tests, a cardiac PET/CT provides superior resolution and sensitivity, allowing doctors to detect disease before symptoms appear.

This imaging scan is especially valuable for:

• Assessing myocardial viability
• Diagnosing coronary artery disease (CAD)
• Guiding treatment plans

Cardiac PET/CT scans are considered the most reliable method for cardiac perfusion imaging by the American Society of Nuclear Cardiology.

Cardiac PET/CT scans are recommended for individuals with:

• Difficulty tolerating longer imaging sessions
• History of heart attacks or cardiac events
• Prior heart procedures, like angioplasty or bypass surgery
• Risk factors or family history of heart disease
• Symptoms of CAD, including chest pain, fatigue or shortness of breath

Speak with your cardiologist if you’d like more information on cardiac PET/CT scans.

Inclusive and accessible

Cardiac PET/CT scans are effective even for patients with pacemakers, obesity or other factors that may interfere with traditional imaging. Covenant’s investment in this technology ensures that advanced cardiac care is available close to home for patients across West Texas and eastern New Mexico.

Lower radiation, greater comfort

The scan uses short-lived tracers, resulting in lower radiation exposure. Most tests take less than an hour, and the process is non-invasive – no surgical procedures or injections into the heart.

Personalized treatment planning

By evaluating myocardial blood flow and identifying viable heart tissue, a cardiac PET/CT scan helps physicians tailor treatments to each patient’s unique needs. It also supports long-term monitoring and management of heart conditions.

Unmatched diagnostic accuracy

Cardiac PET/CT scans can detect even subtle abnormalities in blood flow, making it more precise than older imaging methods like single-photon emission computed tomography (SPECT). It’s particularly effective when other tests are inconclusive or when patients have complex conditions.

Before your appointment, you’ll need to follow specific preparation directions from your doctor, these include:

• 48 hours before: Refrain from taking any blood thinner, antiplatelet, bronchodilator or vasodilator medications, unless directed otherwise by your doctor.
• 24 hours before: Avoid caffeine for the full 24 hours prior to your scan.
• 4 hours before: Fast from all foods and beverages per your doctor’s instructions. You can drink water, juice and electrolyte beverages like Gatorade®. Patients with diabetes should bring their diabetic medications to the appointment and wait until they can be taken with food.
