In DEXA scans, how can dose reduction be achieved when scanning the right hip versus the left hip?

In DEXA (Dual-Energy X-ray Absorptiometry) scans, dose reduction is achieved based on the varying requirements for imaging different body parts. The left and right hips may have different exposure needs due to anatomical variations, but the significant point is that the DEXA system is designed to optimize dose efficiency based on the targeted area.

When scanning the right hip compared to the left hip, reducing the dose by approximately three times allows for adequate imaging while minimizing radiation exposure to the patient. This notable reduction is attributed to the advanced technology used in DEXA, which can effectively measure bone density with lower radiation doses, particularly for areas with typically high bone density like the hips where precise measurements are necessary.

This reduction is crucial for patient safety and comfort, allowing repeat scans when necessary without accumulating excessive radiation exposure. The ability to lower the dose while still obtaining reliable results is key in radiation safety practices and aligns with the principles of minimizing radiation exposure as much as possible while achieving diagnostic efficacy.
