How to optimize examination quality for obese patients during a bone density scan?

For hip scans, abdominal tissue should be moved or held out of the X-ray field of view. For total body scans, patients should place their hands vertically along their bodies with the fifth finger on the mattress, ensuring limbs stay within the table boundaries. For patients weighing over 227 kg (500 lb), a forearm scan is the recommended procedure.
