Key result
A single midthigh MRI slice was the best predictor of whole body intermuscular adipose tissue across all groups (adjusted R2 ranging from 0.49 to 0.84).
Why the study?
Can single-slice MRI measurements accurately estimate whole body intermuscular adipose tissue volume in healthy adults?
Population
142 healthy adults, including African-American women, Asian women, Caucasian women, and Caucasian men.
Comparison
Single-slice MRI measurement of intermuscular… vs Whole body MRI measurement of IMAT volume
Design
Cross-sectional

May support single-slice MRI for group-level estimates; leaves open prospective validation before clinical use.

Can single-slice MRI measurements accurately estimate whole body intermuscular adipose tissue volume in healthy adults?
Effect estimate: adjusted R2 0.49 to 0.84
A single midthigh MRI slice provides a strong estimate of whole body intermuscular adipose tissue, offering a cost-effective alternative to whole body imaging in group studies.
Ruan et al. (2006) conducted a cross-sectional in Healthy adults (n=142). Single cross-sectional MRI slice vs. Whole body MRI was evaluated on Total body IMAT volume (adjusted R2 0.49 to 0.84). A single midthigh MRI slice was the best predictor of whole body intermuscular adipose tissue across all groups (adjusted R2 ranging from 0.49 to 0.84).
