Radiation Protection on Fluoroscopy: An Overview

Fluoroscopy is the examination of body structures using real-time imaging. This technology is widely used in medical diagnostics to examine organs such as the heart, liver, intestines, blood vessels, and bones. However, its reliance on ionizing radiation can pose risks if proper safety measures are not taken. In this article, we will discuss various aspects of radiation protection related to fluoroscopy, including radiation doses and their implications.

Radiation Doses in Fluoroscopy

Radiation dose is a measure of the amount of radiation a patient receives during a medical procedure. This can be quantified in different ways, such as the air kerma-to-dose ratio (KDR), which is the ratio of the air kerma (the amount of ionizing radiation absorbed by air) to the dose to the skin.

Fluoroscopy procedures typically involve x-rays, which use ionizing radiation to produce images. The radiation dose can vary depending on the specific procedure and the equipment used. For example, a single x-ray of the abdomen can expose a patient to about 1 to 3 mGy of radiation.

Radiation Safety in Fluoroscopy

To minimize the risks associated with ionizing radiation in fluoroscopy, several safety measures are employed. These include:

Distance: The distance between the patient and the x-ray source is increased to reduce the radiation dose.
Collimation: This involves using a device to limit the area of the body exposed to radiation.
Shielding: The use of protective barriers, such as lead aprons, can reduce the amount of radiation the patient receives.
Time efficiency: Minimizing the time the patient spends under the x-ray beam can also reduce the radiation dose.

Radiation Dose Limitations

The amount of radiation a patient can safely receive is regulated by organizations such as the US Food and Drug Administration (FDA) and the ALARA (As Low As Reasonably Achievable) principle. The FDA has set limits on the amount of radiation that can be delivered to critical organs, such as the skin, thyroid, and gonads.

Conclusion

Radiation protection in fluoroscopy is crucial to ensure the safety of patients. By understanding the principles of radiation dose and implementing appropriate safety measures, medical professionals can reduce the risks associated with ionizing radiation and provide accurate and reliable diagnostic information. It is essential to continue research and development of safer imaging technologies as well as improve the existing practices for radiation protection in fluoroscopy procedures.
