A nuclear heart scan, also known as a nuclear stress test or myocardial perfusion scan, is a type of imaging test used to examine the heart's structure and identify blockages in the coronary arteries. This non-invasive test uses small amounts of radioactive materials to create detailed images of the heart.
When it comes to the duration of a nuclear heart scan, the process typically involves a few main steps: the preparation stage, the test, and the imaging phase. Here's a breakdown of what to expect and how long each part typically lasts.
Preparation for a nuclear heart scan usually starts a few hours in advance. The patient will be asked to fast for several hours prior اسکن قلب to the test to avoid any interference from food in the digestive system. Additional instructions may include taking certain medications. Finally, the patient will be given a small, dissolvable tablet to swallow, which contains the radioactive material needed for the test. This usually takes around 30 minutes to dissolve.
Once the tracer substance is absorbed into the bloodstream, the patient will be asked to rest for a period of around 45 minutes to an hour. This allows the substance to reach the heart and its surrounding tissues. The resting period is crucial as it helps to get a good picture of the heart before any stress is put on it, which is a part of a more general assessment of the coronary arteries.
The second part of the nuclear heart scan involves exercise to increase overall fitness and heart health. This may be done via body exercises and physical movement. The type of exercise a patient will undergo depends on their health status and ability to exercise. The duration of this exercise period can vary depending on the person but on average, it typically lasts about 20-30 minutes.
After exercising and generating a first set of images, the scanning process itself only takes around 15-25 minutes. The technician will typically position the patient on a table with detectors near the heart and take a series of images from multiple angles. This is usually an automated process that occurs in a quiet room.
In total, the total duration of the nuclear heart scan can vary, but typically the entire process usually takes around 2-4 hours. This broad range is due to a variety of factors including preparation time and the types of procedures that may be used.
