Optional Atypical Femur Fracture (AFF) software uses Femur images to visualize focal reaction or thickening along the lateral cortex of the femoral shaft which may be accompanied by a transverse radiolucent line. This software provides measurements of the lateral and medial cortex width and quantifies focal thickening of the lateral cortex along the femoral shaft. The beaking index can be displayed and trended across serial scans.

Optional sarcopenia software calculates values based on published definitions and thresholds using measured appendicular lean mass in combination with patient demographics and entered values of muscle strength and physical performance. These values may be useful to health care professionals in their management of sarcopenia.

Indications for use as stated in the FDA summary.
