A comparison between manual and semi-automated segmentation was conducted. Further, abdominal VAT and SAT sex-based comparison in healthy Arab adults was piloted. <strong><em>Methods</em></strong>: A cross-sectional design was followed to recruit subjects. Abdominal VAT and SAT were determined on T2-weighted MRI manually and semi-automatically. Body composition was assessed using a BIA machine. Statistical differences between the abdominal VAT areas defined by BIA, manual, and semi-automated MRI were compared. Correlation between all methods was assessed, and statistical differences between sex abdominal VAT/SAT defined areas were compared. <strong><em>Results</em></strong>: A total of 165 abdominal T2-weighted MR images taken for 55 overweight/obese adult subjects were analyzed Differences between manual and semi-automated MRI-obtained abdominal VAT and SAT were found statistically significant (<em>P<</em>0.001) for all subjects. Mean abdominal VAT using the BIA technique was found to correlate significantly with manually and semi-automated T2-weighted MRI defined VAT (<em>r=</em>0.7436<em>; P</em><0.001 and <em>r=</em>0.8275<em>; P</em><0.001, respectively). Abdominal VAT was significantly (<em>P<</em>0.001) different between male and female subjects accumulating at different abdominal levels. <strong><em>Conclusion</em></strong>: Semi-automatic segmentation showed a stronger significant correlation with BIA compared to manual segmentation, implying a more reliable quantification of abdominal VAT/SAT. Segmental BIA technique may serve as a feasible and convenient assessment tool for the visceral adiposity in obese subjects.</p>}, number={3}, journal={Acta Biomedica Atenei Parmensis}, author={Dalah, Entesar and Hasan, Hayder and Madkour, Mohammed and Obaideen, Abdulmunhem and Faris, Moez Al-Islam}, year={2021}, month={Jul.}, pages={e2021078} }
