CT Assessment of Normal Splenic Size in Children

Abstract

The size of the normal spleen was estimated by CT in 153children, examined with indication unrelated to splenic disease. In each patient the width, thickness, length and volume of the spleen were calculated. Measurements were also normalized to the transverse diameter of the body of the first lumbar vertebra. The spleen underwent significant growth during the first 4 years of life and reached maximum size at the age of 13. There were no differences in splenic volume between boys and girls. Splenic thickness correlated best with normal splenic volume. The strongest correlation was also found between splenic thickness and volume in a group of 45 children with clinically evident splenomegaly. Splenic thickness, an easy-to-use measurement, may be employed in everyday practice to represent splenic volume on CT.

Liver/spleen volume ratio as a predictor of prognosis in primary biliary cirrhosis

“…Liver and spleen volumes correlate with body surface area and age, respectively. 13,14 Therefore, we used the LV/SV ratio to decrease the infl uence of these factors.…”

Determination of normal splenic volume on computed tomography in relation to age, gender and body habitus

“…Spiral CT avoiding errors due to respiratory movements is expected to be even more accurate in assessing splenic volume. Although the summation-of-areas technique has been applied for measuring the splenic volume [7,8,11] the corresponding normative data has not been previously established. However, measuring the splenic volume by that technique is cumbersome for use in regular practice.…”

“…In vivo, only significant splenic enlargement can be diagnosed clinically [3,4]. Splenic size can be reliably evaluated in vivo employing imaging methods [5][6][7][8]. There are however, problems in definition of splenomegaly [9].…”

Thoracoabdominal Organ Volumes for Small Women

“…Medical images are commonly used to assess organ volumes in vivo (Prassopoulos and Cavouras 1994;Prassopoulos et al 1997;Schiano et al 2000;Zhu et al 1999). Currently, one of the largest data sets available for organ volume comparisons was published by Geraghty et al (2004).…”
