A myocardial perfusion scan is a diagnostic test used to assess the blood flow to the heart and identify any blockages to the heart muscle. It's a diagnostic tool used primarily to detect coronary artery disease and other heart-related ailments. In this article, we will take you through the guide of a nuclear heart scan procedure, so you know what to expect during the test.
Step 1: Getting Ready
The nuclear heart scan test requires some readiness beforehand. You will be asked to skip consuming anything containing tea for at least 24 hours prior to the test. You may also need to stop taking any medications before the test, such as beta blockers, as they can hinder the results. Additionally, inform your doctor about any allergies, especially if you've had an allergic reaction to a previous nuclear imaging test.
Step 2: Preparation for Imaging
On the day of the test, you will be asked to arrive at the imaging center about 30 minutes before the scheduled appointment time. You will be asked to change into a hospital gown or gown-like garment. You will also be asked to take off any jewelry, glasses, and other items that may inhibit the scan.
Step 3: Contrast Agent Injection
During the test, you will be injected with a small amount of a radioactive contrast agent through an IV (intravenous) line. This contrast agent is attached to an amino acid molecule that adheres to the heart muscle. The medication used is typically a technetium compound and is commonly used in nuclear imaging tests.
Step 4: Relaxation Session
After the injection, you will be asked to rest for 20-30 minutes to enable the contrast agent to travel to the heart muscle and bind. You will be seated comfortably in a quiet room during this time, and you can unwind and listen to music or engage in light conversation.
Step 5: Exercise Stress Test
If your doctor suspects coronary artery disease or other conditions that require exercise, a cardiac stress test will be performed before or after the nuclear scan. This involves walking on a exercise machine while wearing an electrocardiogram (ECG) monitor to track your heart's electrical activity. This will be followed by the nuclear scan after relaxing for a few minutes.
Step 6: اسکن قلب Nuclear Scan
Once the contrast agent has taken effect, you will be asked to move to a scanning room where a large scanner is located. You will lie on your back or sit in an upright position while the scanner captures images of your heart muscle over a few minutes. The scanning process itself is harmless and takes about 10-20 minutes.
Step 7: SPECT Imaging Test
Depending on the type of nuclear scan performed, the scanner may be rotated several times around your body, and you will need to stay motionless for a short period. This type of scan is called a cardiac SPECT (Single Photon Emission Computed Tomography) scan.
Step 8: Result Interpretation and Follow-up
After the test, you will need to relax for a short period before leaving. Your doctor will review the radioactive stress test images and combine the results with other information to detect the presence of coronary artery disease or identify any other potential issues. You will be contacted by your doctor with the results, and if required, you may need to undergo further tests or begin treatment.
Keep in mind that while a nuclear heart scan is considered safe, it does involve risk to small amounts of radiation. This exposure is a vital tool in helping medical professionals diagnose and treat various heart-related conditions.
