Abstract

Objective: Determine normal spleen volume in adults without diseases affecting spleen index on CT. Subjects and methods: A cross-sectional descriptive study on 200 adults with an average age of 51,7 ± 14,2 years was performed to measure spleen indices on CT scan. Results: The mean spleen volume in adults was 136,4cm³ (±50,8SD). There was a statistically significant difference (p=0,002) between men and women. The study also showed that there is a difference in spleen volume between the age group under 40, 40-60 years old and over 60 years old (p<0,05), which shows that age is a factor affecting the volume of the spleen, specifically as we age, the volume of the spleen decreases. There was a strong relationship between the maximum height and width of the spleen and the volume of the spleen (r=0,704 and r=0,723). In addition, the study showed that the maximum height greater than 10,3cm is the threshold to consider the diagnosis of splenomegaly. The study also showed that there was no statistically significant difference between the reusults of measuring spleen volume on 3D reconstructed CT compared with the classical formula for calculating spleen volume V = 0,58x L x D x T + 30. Conclusion: possible spleen volume in adult men: 146,7 ± 53,4cm³, female: 124, 7 ± 45,2cm³, both sexes: 134,4 ± 50,8 cm³, maximum spleen height in men 10,6, female 9,9cm, both sexes: 10,3cm.
