Skeletal muscles include fast and slow muscle fibers. However, a non-invasive approach for appropriately investigating the characteristics of muscles is not available. The present study aimed to determine whether q-space imaging can distinguish between fast fiber dominant tibialis anterior muscle (TA) and slow fiber dominant soleus muscle (SOL). T2WI, FA and ADC maps could not represent the difference between TA and SOL. On the other hand, Kurtosis map could visualize the characteristics of TA and SOL. q-space imaging is a promising method to non-invasively estimate the fiber type ratio in skeletal muscles.
