Ultrasound has been found to be accurate, reliable and noninvasive method in the measurement of spleen. The study was undertaken to obtain standard values of size in three dimensions and normal range of splenic volume by the use of splenic volumetric index(SVI) in normal korean adults.

We experienced 100 cases of abdominal ultrasonography of normal korean adults from May 1995 to August 1995.

1) The average size of spleen in adult male was 6.85±1.31cm in breadth, 4.93±1.27cm in thickness, 6.33±1.46cm in height ; in adult females, 6.61±1.23cm, 5.17±1.26cm, 6.33. 42cm, respectively ; total average, 6.73±1,27cm, 5.05±1.27cm, 6.33±1.39cm,respectively.

2) The average splenic volumetric index in adult male was 8.20±3.95; in adult females, 8.41±4.08 ; total average,8.31±4.00. There were no statistical differences of SVI and size between sex and age.

Although ultrasonography is less accurate than computed tomography, it is rapid and simple method for splenic measurement.
