A nuclear heart scan, also known as a cardiac stress test, is a non-invasive medical imaging exam that helps diagnose various heart conditions and diseases

Types of Nuclear Heart Scans

Physicians typically use two primary types of nuclear heart scans: pharmacological testing and physical testing Nuclear heart scans involve exercise testing, which uses a radioactive material to measure heart health while the patient is physically active. or The pharmacological method involves injecting patients with medication that mimics the effects of physical exercise.

The Technology Behind Nuclear Heart Scans

Nuclear heart scans involve a gamma camera, which captures images of the heart muscle. This camera measures the amount of radioactive material present in the heart, giving doctors insight into heart function. Before the scan, a small amount of radioactive material is injected into the bloodstream, through a vein via a catheter. This accumulates in areas with increased blood flow.

Clinical Applications of Nuclear Heart Scans

Nuclear heart scans are used to diagnose and monitor various heart conditions:
High blood pressure or hardened arteries can impact coronary arteries, detected by nuclear heart scans..
Nuclear heart scans can diagnose irregular heartbeats, or arrhythmias.
Heart scans provide valuable information about a patient's heart performance.
Cardiac tumors: Nuclear heart scans can help diagnose and monitor cardiac tumors, such as metastatic cancers
Congenital heart defects: Nuclear heart scans can help diagnose and monitor congenital heart defects, such as ventricular septal defects or atrial septal defects

Preparing for a Nuclear Heart Scan

Patients must undergo an ECG before the scan. They may need to discontinue specific medications to improve test accuracy. On the day of the scan, patients will usually be asked to remove any metal objects, اسکن هسته ای such as jewelry or watches, and lie on a bed or table under a specialized camera

Interpreting Nuclear Heart Scan Results

A nuclear medicine expert will determine the results based on heart images and gamma ray findings. The results will help answer key questions about the patient's heart function and diagnose any underlying heart conditions

Conclusion

Heart scans are a vital tool in modern medicine. Doctors can better serve their patients by explaining nuclear heart scan procedure. By identifying areas of increased or decreased blood flow, nuclear heart scans can guide cardiologists in determining the best course of treatment.
