If you’ve been referred to Concord Imaging Center in San Antonio for nuclear medicine, you probably have some questions about what to expect. This kind of medical imaging test might sound intimidating, but in reality, it is virtually painless and involves no more radiation than a typical X-ray.
When you go in for a nuclear medicine imaging test, you will receive an injection of a radiopharmaceutical substance. The needle prick is the only part of the test that causes even mild discomfort. After the injection, you will wait a specified amount of time for the substance to travel to organs that are being tested. When it is time for the scan, you will be asked to remain still so that the images are as clear as possible. Depending on the reason for your test, the scan will take between 20 and 45 minutes. After your test, any small amount of radiation in your body will be expelled through urine and stool for up to a few days after the scan.
