Nuclear medicine studies of aging: X. Relationship of liver and spleen lengths at age 65 years and older

Abstract

For 3 groups of patients aged 65 years or greater, liver and spleen lengths were measured from calibrated radiocolloid images. Length relationships between liver (L) and spleen (S) were examined in terms of S as a function of L, as well as (S/L) and (L-S) vs S or L. Liver and spleen lengths were the least well correlated in these patients. The S/L ratio vs S produced the most significant correlation in all 3 groups. This suggests a complex but describable relationship between liver and spleen lengths in the overall aging population, and provides a baseline for comparing the effects of various diseases on S and L.
