Splenic length, thickness, width and volume were obtained as follows: splenic length was defined as the maximum distance between the dome of the spleen and tip of the spleen on a longitudinal section in the sagittal plane) (SL), splenic width was defined as the maximum distance between the medial and lateral borders of the spleen (it was measured in a plane perpendicular to the length) (SW); splenic thickness was defined as the distance between the inner and outer surface (it was measured at the level of the splenic hilum on a transverse section) (ST) and splenic volume was calculated with the following standard elipsoid formula as; 0.524 x width x length x thickness.
