Evaluation of Agreement Between CT Scan and 3D-DXA Measurements on the Lombar Spine

Dual‐energy X‐ray Absorptiometry is frequently used to measure bone mineral density. A new medical device, Box 3D DXA, creates a 3D image using a statistics reconstruction model developed on the femur. This new imaging technique does not require additional irradiation and ought to improve bone measures as well as incorporating densitometric parameters into the diagnosis. This study will test the reconstruction of the 3D image from lombar spine measurements and compare accuracy against measurements made using CT scan.
