Which practice is recommended for achieving the best image quality in fluoroscopy?

Using the highest kilovolt peak (kVp) along with the lowest milliamperage (mA) is recommended for achieving the best image quality in fluoroscopy because it optimally balances image contrast and patient dose. High kVp settings improve the penetration of the X-rays through the body, which enhances the contrast of structures within the image. This allows for clearer visualization of the anatomy being examined, especially in situations where there is significant density variation.

In addition, low mA settings help to reduce the overall radiation dose to the patient while still maintaining adequate image quality. The combination of high kVp and low mA allows for a clearer image with less noise, which is essential in dynamic studies commonly performed in fluoroscopy, enabling better diagnostic outcomes.

This practice contrasts with options that suggest minimal filtration, lower mA settings alone, or long exposure times, all of which would not optimize image quality or might increase the radiation dose unnecessarily without improving the clarity of the images.
