Which factor is most important in reducing patient exposure during a fluoroscopic procedure?

The most important factor in reducing patient exposure during a fluoroscopic procedure is using the lowest effective dose of radiation. Justification for this stems from the principle of ALARA (As Low As Reasonably Achievable), which is fundamental in radiation safety practices. By focusing on minimizing the radiation dose to the patient while still achieving the necessary imaging quality, healthcare professionals can effectively reduce the risk of potential radiation-related adverse effects.

When applying this approach, practitioners are encouraged to select the appropriate imaging parameters and techniques that allow for a quality diagnostic image with the least radiation exposure. This means that decisions regarding equipment settings, patient positioning, and the duration of the procedure should all be aimed at achieving the best possible results without unnecessary radiation.

While using lead aprons and increasing kilovolt peak (kVp) can contribute to radiation protection, they do not address the core principle of minimizing the overall radioactive exposure during the procedure. Reducing exposure time also plays a role, but the ultimate goal should always be to use the lowest effective radiation dose to achieve the requisite diagnostic objectives, making it the most important factor in patient safety during fluoroscopy.
