What are the risks of nuclear imaging?

There are minimal risks when conducting a nuclear medicine study. These are allergic reactions and radiation risk. Allergic reactions have been reported, but they are very rare and almost always mild. All medical procedures performed on anyone, whether a child or an adult, carry some risk of injury.

The risk of injury can be small or large depending on the type of activity being performed. In nuclear medicine, the radiation risk of routine nuclear medicine testing is generally perceived to be very small, but limited. There are several ways to communicate this risk and this varies from place to place. Once the information considered essential to be communicated to a patient is agreed upon, the next step is to identify the best person or groups of people who can communicate this risk to patients.

Legal precedents established by bodies such as the International Commission on Radiological Protection indicate that this risk is best identified by the referring physician at the time of the decision to request the test, taking into account the demographics, clinical presentation of the patient and any influence on the management of the patient as a result of the test in question. On a more practical level, patients are more likely to be informed of the radiation risk through a leaflet prior to the test and are given the opportunity to discuss the risks and benefits of the test with department staff. What is clear is that patients definitely need to be informed of the risks prior to the procedure and should be given the opportunity to discuss this matter in more detail with a trained person. Nuclear therapeutic procedures include radioactive iodine (I-13) therapy and radioimmunotherapy.

Radioimmunotherapy combines radiation therapy and the targeting capacity of immunotherapy. Immunotherapy mimics cellular activity in the body's immune system, so radiation is able to target affected areas very precisely. Therapeutic nuclear medicine is generally used for severe types of cancer and diseases affecting the thyroid gland. Radioactive tracers used in nuclear medicine are, in most cases, injected into a vein.

For some studies, they may be given orally. These markers are not dyes or medications and have no side effects. The amount of radiation a patient receives on a typical nuclear medicine scan tends to be very low. Learn more about the benefits and risks of imaging tests, including nuclear medicine, and how to reduce your radiation exposure.

The dose of ionizing radiation for these procedures is usually higher than the dose received from a common X-ray procedure. There are always some possible risks from exposure to ionizing radiation in healthcare, but these procedures should be used when the health benefits outweigh these risks. The Nuclear Regulatory Commission (NRC), the U.S. UU.

The Food and Drug Administration (FDA) and states regulate the use of radioactive materials for nuclear medicine to ensure that patients, medical staff and the public are safe. Before using any type of nuclear medicine procedure, it must be justified to ensure that the benefits of the procedures outweigh the risks to the patient. However, exposure to too much radiation can quickly damage organs or tissues, while exposure to any amount of radiation can increase the risk of cancer years after exposure.

Although nuclear imaging is commonly used for diagnostic purposes, they also have valuable therapeutic applications, such as treating hyperthyroidism, thyroid cancer, blood imbalances, and any bone pain caused by certain types of cancer. When you know the pros and cons of nuclear medicine scans, you can rest easy knowing that nuclear imaging is safe. While individual nuclear medicine professionals retain local responsibility and accountability, specialized societies have a clear role to play in assisting in the safe and efficient practice of nuclear medicine. As an integral part of patient care, nuclear imaging is used in the diagnosis, management, treatment and prevention of serious illnesses.

The radiation risk that arises from nuclear medicine research represents a small but manageable risk for patients and needs to be effectively communicated to them. Slovic's fundamental study in 1987 showed that the general public may have fundamentally different ideas about the risk derived from nuclear technology compared to experts in the field, even when nuclear technology was compared to daily activities, which were quite risky in nature. Similarly, most patients undergoing a nuclear medicine procedure would like to believe that the chances of developing some complications as a result of a diagnostic test are more theoretical than those applicable individually. The main difference between nuclear medicine imaging and other radiological tests is that nuclear medicine imaging evaluates organ function, while other imaging methods evaluate anatomy (how organs look).

In research, the level of risk is considered “trivial” if the effective dose is 10 mSv. In many ways, nuclear imaging tests are the most sophisticated and accurate diagnostic tests available. Thanks to their special training, the nuclear doctor can select the most appropriate examination for the patient's particular medical problem, thus avoiding any unnecessary exposure to radiation. There are no general rules for preparing for the nuclear medicine test, as each type of test has its own requirements.
