What is a Nuclear Medicine Stress Test?

A Nuclear Medicine Stress Test evaluates blood flow to the heart both at rest and during stress, helping to diagnose various heart conditions, including coronary artery disease.

How Does It Work?

Preparation:

      • Fasting: You may need to fast for 4-6 hours before the test.
      • Medications: Inform your doctor about any medications you’re taking, as some may need to be paused.
      • Caffeine: Avoid caffeine for 24 hours before the test.
      • Medical Records: Bring any relevant medical documents or instructions from your doctor.
      • Blood Tests: Blood test results for Creatinine and BUN may be required within 30 days prior to the exam for patients aged 60 and over, as well as patients with chronic kidney disease, diabetes, or hypertension. Please ask your physician to order the blood tests and fax the results prior to the appointment or bring them with you on the day of your appointment.
      • Pregnancy Test: Required for patients of childbearing age.
      • Inform Your Doctor: Let your doctor know if you have allergies to iodine contrast material, kidney problems, or are pregnant.

During the scan

          • Injection: A small amount of radioactive tracer is injected into a vein.
          • Resting Images: Initial images of your heart are taken while you are at rest.
          • Stress Phase: You will either exercise on a treadmill or receive a medication that simulates exercise by increasing blood flow to your heart.
          • Stress Images: Additional images are taken to compare blood flow during stress and at rest.

Procedure:

  • Remove Metal Items: You’ll need to remove any metal objects, such as jewelry, as they can interfere with the imaging.
  • Stay Still: It’s important to remain still during the scan to ensure clear images.
  • Duration: The entire process usually takes about 2-4 hours, including preparation and imaging.

What to Expect?

  • Comfort: The procedure is generally well-tolerated, though you may feel some discomfort from the injection or exercise.
  • Radiation: The level of radiation exposure is low and considered safe.
  • Results: The results will be analyzed by a cardiologist and sent to your referring physician within 24-72 business hours.

After the Test:

  • Normal Activities: You can usually resume normal activities immediately after the test.
  • Follow-Up: Your doctor will discuss the results with you and recommend any necessary treatments or lifestyle changes.

Purpose of the Test:

  • Diagnosing Heart Conditions: Helps in diagnosing coronary artery disease and other heart conditions.
  • Monitoring Heart Health: Used to monitor heart health and the effectiveness of treatments for heart disease.
