Fig. 1.

Schematic representation showing the planes and reference points for liver and spleen measurements. Left liver lobe plane is established by the midsternal line and right liver lobe plane by the midclavicular line. Spleen measurements are performed in the craniocaudal course of the intercostal spaces at the level of the splenic hilum. Measurements are performed between the most superomedial and the most inferolateral points of the spleen. The transverse diameters are measured at right angles to the craniocaudal measurements
