A Nuclear Heart Scan is a type of imaging procedure used to visualize the heart's structure and is a diagnostic tool that evaluates the heart's structure and function in great detail thoroughly. It is also known as myocardial perfusion imaging (MPI) and is commonly used to diagnose and manage various heart conditions.

In a Nuclear Heart Scan, a small amount of radioactive material, known as a tracer substance a radioactive agent, is injected into the bloodstream via an intravenous line. This tracer is attracted to the heart muscle, allowing it to be imaged using a special machine that detects the tiny amounts of radiation emits the tiny amounts of radiation emitted by the tracer. The scan provides detailed information about the heart's pumping function, blood flow, and blood flow reserve.

Types of Nuclear Heart Scan:

There are several types of Nuclear Heart Scan procedures, including:

SPECT (Single Photon Emission Computed Tomography): This is the most common type of Nuclear Heart Scan, which involves rotating around the patient's body to capture images.
PET (Positron Emission Tomography): This type of scan uses a more sensitive detector to produce high-resolution images of the heart.

Benefits of Nuclear Heart Scan:

A Nuclear Heart Scan has several benefits over traditional imaging techniques, including the ability to:

Provide detailed images of the heart's structure and function
Show how well the heart muscle receives the necessary resources
Identify areas of damaged or scarred heart tissue.

Common reasons for undergoing a Nuclear Heart Scan:

A Nuclear Heart Scan is commonly used to evaluate patients with various symptoms such as chest pain when exercising, اسکن هسته ای قلب shortness of breath, and palpitations. Patients with a history of heart disease, high blood pressure, high cholesterol, and smokers are also likely to undergo a Nuclear Heart Scan.

Preparing for a Nuclear Heart Scan:

Preparation for the procedure is relatively simple straightforward. Patients will need to come to the hospital in the morning on an empty stomach and should avoid caffeine, tobacco, and other stimulants for at least 48 hours prior to the scan. The tracer will be injected intravenously, followed by a series of images. The procedure typically takes a few hours, but the actual scan time is relatively short, approximately 30-45 minutes roughly.
