Which of the following practices can lead to increased radiation exposure during fluoroscopy?

The practice of frequently using the magnification feature during fluoroscopy can lead to increased radiation exposure for several reasons. When the magnification feature is activated, the X-ray tube typically increases the dose of radiation to provide a clearer, more detailed image of the area of interest. This happens because magnification requires a higher radiation output to achieve the necessary image quality and resolution. As a result, the patient's exposure to radiation increases. In addition to increasing dose, using the magnification feature can also reduce the field of view, which may require additional imaging exposures or prolonged fluoroscopy time to ensure that all necessary information is gathered. This combination of higher doses and potential extended procedure times compounds the overall radiation exposure. Other practices, such as using image storage to hold the last image or reducing beam-on time, typically do not increase radiation exposure. Positioning the image intensifier (II) close to the patient can help reduce exposure since it allows for lower radiation doses needed for adequate imaging, as it minimizes the distance between the X-ray source and the II, reducing scatter radiation.
