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 medicines 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: required procedures, the test, اسکن هسته ای and scanning phase. Here's a breakdown of what to expect and how long each part typically takes.
Preparation for a nuclear heart scan usually starts a few hours in advance. The patient will be asked to avoid eating for several hours to avoid any interference from food in the digestive system. Additional instructions may include getting a medical exam. 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 about 30 minutes to digest.
Once the heart medication is absorbed into the bloodstream, the patient will be asked to sit quietly for a while. This allows the substance to reach the heart and its surrounding tissues. The resting period is crucial as it helps to get the best test results 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 blood flow and heart activity. 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 medical 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 nuclear heart scan process can vary, but typically the entire process usually takes around 1.5-3 hours. This broad range is due to a variety of factors including individual variability and test complexity.
