Diaphragm thickness measurement. A line was drawn through the anterior border of the spinal canal at T11 to L1 vertebral body level on the axial image (upper). Software automatically displayed intersection points of the line and diaphragm on the coronal image (lower). Diaphragm thickness was measured at the corresponding points two times on each side of the diaphragm and the mean value was obtained.
