Direct comparison of visceral adipose tissue (VAT) values between the automated algorithm and the manual tracing method (n = 12). a Regression between the manual and automatic data produced an excellent coefficient of determination. b Bland–Altman plot comparing the relative difference in VAT values between the two methods. Solid line represents the mean of the relative differences between the algorithm and the manual data as calculated by (auto − manual) / (average of manual and auto). Dashed lines represent the 95% confidence intervals. c Representative segmented images of abdominal VOIs showing the large range in visceral and subcutaneous adipose volumes.
