DXA Imaging: Comparing LPC & RET. A) Total body DXA image from Hologic QDR-4500W indicating cut-off points (small black horizontal lines) at each measurement site – height was measured from the crown to the heel; B) LPC measure of femur from which number of horizontal lines are automatically calculated as vertical heright of ROI; C) Reticule with its millimetre scale placed over paper image of femur, for RET measurement.
