Chow et al reported equations for the normal size of the spleen in adults based on ultrasound measurements. The authors are from Ambulantes Krebzentrum (Frankfurt), German Red Cross Bllod Service Baden-Wurttemberg-Hesse, Goethe University and the University of Washington in Seattle.
Patient selection: adult 18 to 55 years, healthy
Parameters:
(1) sex
(2) body height in centimeters
upper limit of normal for splenic length in women in cm =
= (0.0282 * (body height)) + 7.5526
upper limit of normal for splenic length in men in cm =
= (0.0544 * (body height)) + 3.6693
upper limit of normal for splenic volume in women in cubic cm =
= (7.5526 * (body height)) - 939.5
upper limit of normal for splenic volume in men in cubic cm =
= (4.3803 * (body height)) - 457.15
