Purpose Our purpose was to assess the fat fraction (FF) and R2* values (R2*) of the vertebrae in healthy subjects with IDEAL-IQ. Materials and Methods 75 patients underwent MRI including IDEAL-IQ and the mean FF and the mean R2* within the spine were evaluated. ANCOVA was performed to investigate gender age and BMI group differences. Results FF increased with advancing age and interaction with gender. Young females showed a low FF. The group of low BMI showed a low FF. Conclusion The quantitative analysis of the vertebrae with IDEAL-IQ can demonstrate those age gender and BMI-related changes.
