Randomized trial compares DXA BMD and predicted BMD in patients with obesity, indicating significant measurement differences.

This study aims to investigate how obesity and central obesity impact DXA-equivalent bone mineral density (BMD) estimation.
Used 710 cases (621 patients) from 2012 to 2021 with abdominal and pelvic CT scans.
Applied gray-level co-occurrence matrices (GLCM) for texture analysis of L1 vertebrae to predict BMD and bone mineral content (BMC).
Divided cases by obesity type and measured various indices including BMI and waist circumference.
Coefficients for BMD predictions were above 0.73 across measures.
P-values showed significant differences for L1 BMD and L1 BMC between obesity groups (0.0131 and 0.0351, respectively).
Central obesity significantly affected clinical BMD measurements based on the ICO standard.
