Fat-water quantification is a promising method for
sensitively measuring changes in muscle in upcoming
clinical trials in neuromuscular diseases. In this work
we applied texture analysis to 3-point Dixon fat
fraction maps to assess fat-infiltration in the
hamstring muscles in 17 patients with the representative
condition inclusion body myositis, measured twice at a 1
year interval. Mean fat-fraction, contrast, homogeneity
run length image texture measures all changed
significantly over 1 year. There were no equivalent
texture parameter changes in a healthy volunteer group
over this period, demonstrating the promise of muscle
fat-fraction texture analysis for measuring longitudinal
fat-infiltration in neuromuscular conditions.
