Characterization of Pancreas in Sudanese Population Using Computerized Tomography

Abstract

This study was conducted to define the normal pancreatic size and texture for Sudanese in order to establish a local reference of values using CT scans. Computerized Tomography Scanning was performed in the Radiology Unit of the Ebn Elhaitham and Alamel Centers in Khartoum-Sudan period 2011 - 2015. The data was collected from 252 normal subjects and were considered as group (A). 31 patients had preexisting diabetes and considered as group (B). patients age, weight, height, abdominal circumference (AC), body mass index (BMI), pancreases head CT number, Pancreas body CT number, pancreas tail CT number, pancreas head size, pancreas body size, pancreas tail size, vertebral body width vertebral body CT number, spleen CT number, for both normal and diabetic group as well as diabetic duration for the affected patients were recorded. Measurement were made and comparison took place between the normal control group and affected patients. Data were presented as mean and standard deviation (SD) for all of the variables. Comparisons between groups showed results which were significant at P < 0.05. The study revealed that the Sudanese pancreas size was 28.16 ± 3.37 mm for head, 23.19 ± 3.74mm for body, 19.05 ± 3.05mm for tail and pancreas texture which was evaluated as Hounsfield was 59.02 ± 14.17for head, 57.22 ± 12.59 for pancreases body and 55.44 ± 13.12 for pancreases tail. The study showed a significant relation between the pancreas size and subject’s age, height, abdomen circumference and vertebral body size, where the pancreas texture has significant relation with age ,height, abdominal circumference body width and texture vertebral and spleen texture.

Equations had been established to predict the Sudanese pancreatic size and texture. comparison between normal and diabetic samples showed that diabetes had impact on pancreas measurements, but there is no effect on pancreas texture. Long duration of DM lead to decline of pancreas size. Sudanese pancreas measurements differ from what was mentioned in other population.
