DXA technique stands for Dual-Energy X-Ray Absorptiometry. It is a technique used to measure the body composition using X ray energy. It is an imaging technique that measures the total body fat and bone mineral density. This technique is also widely used to predict the patient's risk to develop osteoporosis in adults.
Thus, X ray technique is mainly responsible for the prediction of fat distribution pattern such as abdominal visceral fat and DXA technique.
