Diffusion Tensor Imaging (DTI) enables the microstructural examination of muscle tissue as well as its pathological and stress-dependent changes. Little is known about the associations between muscular DTI parameters and corresponding muscle strength measurements. The present study investigated the correlations of DTI parameters of paraspinal muscles with isometric strength measurements in healthy subjects. The results indicate that DTI may potentially track slight changes of back muscle tissue microstructure that relate to muscle strength and may be useful in the early diagnosis of back muscle diseases and back pain.
