Splenic volume in children: Simplified estimation at CT

Measurements of splenic length, width, and thickness were obtained from axial computed tomographic (CT) scans in 50 consecutive children (26 male and 24 female patients, aged 8 days to 19 years) referred for abdominal CT. In addition, the outline of the spleen was traced on individual axial CT sections to obtain the splenic volume with use of the software program in the CT computer. The three splenic dimensions correlated well (r = .97) with the splenic volumes obtained with the more accurate technique of tracing the splenic outline on sequential CT sections.
