Measurements of the diaphragm performed on enhanced CT scan. A Measurement of the pillars at the level of the celiac artery. Minimal diaphragm thicknesses (red lines) at the level of the origin of the celiac artery (red arrow). B Measurement of the pillars at the level of L1. Diaphragm thicknesses (red lines) along the anterior part of the L1 vertebral body at mid-level (red arrow). C Measurement of the diaphragm height difference. Heights (red lines) from the highest point of the diaphragmatic dome to its perpendicular intersection with a line (white line) following the upper plateau of L1 (red arrow)
