a,b, Case study of clinical MRI scans of asymptomatic control subject (CTRL) (a) versus patient (PATHO) (b) with a diagnosed mechanopathology (mid-portion Achilles tendinopathy) in their right foot (n = 1). Representative parameter maps of sagittal planes show \({{\rm{T}}}_{1}\) (top row) and \({{\rm{T}}}_{2}^{\ast }\) (bottom row). Arrows point to the mid-portion of the Achilles tendons. c, Quantification of \({{\rm{T}}}_{1}\) (top) and \({{\rm{T}}}_{2}^{\ast }\) (bottom) in the mid-portions of the left and right Achilles tendons. Bar plots show mean ± s.d. of a region of interest from n = 1 Achilles tendon mid-portions.
