Which of the following is NOT utilized to minimize patient dose during fluoroscopy?

• A. Last image hold
• B. Pulsed fluoroscopy
• C. Continuous fluoroscopy
• D. Post exposures

Answer: (C)

Continuous fluoroscopy is the option that does not contribute to minimizing patient dose during fluoroscopic procedures. Continuous fluoroscopy delivers a constant stream of x-ray exposure, leading to higher cumulative radiation dose to the patient during the procedure.

In contrast, strategies like last image hold and pulsed fluoroscopy are designed specifically to reduce patient radiation exposure. Last image hold allows the operator to freeze the last captured image on the monitor, enabling the clinician to review the image without needing additional x-ray exposure. Pulsed fluoroscopy provides intermittent x-ray exposure rather than a continuous stream, effectively reducing the overall dose while still allowing for real-time imaging during the procedure.

Post exposures may refer to additional imaging taken after the initial fluoroscopy, and while they can contribute to dose if not managed correctly, they are not standard techniques employed during fluoroscopy to minimize patient dose. The correct answer highlights the importance of understanding how different fluoroscopy techniques impact radiation exposure.
