Figure 7a. Proximal MTJ strain in an elite athlete. Differentiation between muscle soreness following training and a small hamstring tear was difficult at clinical examination. (a, b) Axial (a) and coronal oblique (b) MR images demonstrate a small region of hyperintensity in the biceps femoris (curved arrow), a finding that is consistent with edema as a result of a subtle MTJ tear (straight arrow). (c) Corresponding transverse US image demonstrates a hypoechogenic area of edema (curved arrow) around the MTJ (straight arrow).
