Cardiac PET is an advanced imaging technique that assesses blood flow to the heart

A PET camera will take pictures of your heart in two phases—a resting phase and a stress phase. These phases are then compared to allow for the assessment of blood flow through your heart and/or to look for prior damage to the heart muscle. Regadenoson is injected during the stress phase of the cardiac PET to dilate the coronary arteries.

Most cardiac PET studies are completed in less than an hour here at Baylor Scott & White Legacy Heart Center in Plano.

El Colegio Estadounidense de Cardiología y la Asociación Estadounidense del Corazón afirman que las exploraciones PET han demostrado una precisión diagnóstica estadísticamente significativamente mayor para detectar la enfermedad de las arterias coronarias.

Preparing for your cardiac PET appointment

  • Use ropa suelta y cómoda y zapatos cómodos para caminar.
  • Debido a que su presión arterial se controlará periódicamente durante la prueba, use una camisa o blusa de manga corta.
  • No use botas, monos, monos o un vestido.

  • Do not eat anything four hours prior to the stress test. If you are diabetic, follow your normal regimen but eat light. You may have juice before the test if needed.
  • Please do not smoke or exercise eight hours before testing.
  • Debe continuar tomando TODOS los medicamentos, a menos que su cardiólogo le indique lo contrario.

What to expect during a cardiac PET

When you begin the cardiac PET at our heart center in Plano, a small IV line will be placed in a vein in your arm. The IV will allow us to inject a small amount of a radiopharmaceutical so that the PET camera can take pictures of the heart. You will be asked to lie on a scanning table made especially for the PET camera.

A blood pressure cuff will be placed around your other arm to monitor your blood pressure during the test. Electrodes will be placed on your chest to monitor your electrocardiogram throughout the test.

Se acostará boca arriba con los brazos por encima de la cabeza mientras la cámara toma imágenes del flujo de sangre al corazón desde muchos ángulos diferentes. Durante este proceso, se inyectará Regadenoson para obtener imágenes de estrés. Las imágenes se almacenan en forma digital en una computadora especial.

Who will give me the results?

After a review of the test, your medical history, other imaging modalities and previous tests by a Baylor Scott & White Legacy Heart Center cardiologist, a report will be sent to the ordering physician. The ordering physician will then review and provide the results.
