Morphometric Study of Spleen in North Indian Adult Population: CT Scan Image Based Study

Introduction : A prospective study was done on 126 patients (72 male and 54 female) whose abdominal CT scan was found normal and no disorder was diagnosed which alters the size of spleen to estimate normal linear dimensions of spleen in North Indian adult population. Material & Methods : Collected CT scan were evaluated with the help of Able 3-D doctor software. Body habitus of patients were determined. All linear dimension of spleen - length, width and thickness were calculated and they were analysed with body habitus - Age, height, weight, BSA (body surface area) and BMI (body mass index) was calculated by linear and non-linear regression model to know exact pattern of correlation. Result : The mean length, width and thickness of spleen were 10.67 +/- 1.62 cm, 6.26 +/- 1.66 cm and 4.86 +/- 1.22 cm respectively. Conclusion : All linear splenic dimensions have significant positive correlation with height of patients and normative data can be produced with the help of regression formula developed with the help of statistics which can be used as research tool where objective determination of splenomegaly is required.
