A nuclear heart scan, also known as a nuclear stress test or myocardial perfusion scan, is a type of imaging test used to evaluate the heart's pumping function and blood flow. This non-invasive test uses small amounts of tracer substances 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 may last.
Preparation for a nuclear heart scan usually starts a few hours in advance. The patient will be asked to fast for several hours prior to the test to avoid any interference from food in the digestive system. Additional instructions may include showering and changing into comfortable clothing. Finally, اسکن قلب 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 radioactive material 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 heart rate and stress on the heart. This may be done via physical activity, running, or cycling. The type of exercise a patient will undergo depends on their medical history and physical fitness. The duration of this exercise period can vary depending on the person but on average, it typically lasts about 15-30 minutes.
After exercising and generating a first set of images, the scanning process itself only takes around 20-45 minutes. The technician will typically position the patient on a table with photographic equipment near the heart and take a series of images from multiple angles. This is usually an automated process that occurs in a peaceful atmosphere.
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.
