Evolution of healing by MRI over a course of 12 weeks: rectus femoris central myoconnective junction. Axial T1- and fluid-sensitive images at 1–2 weeks (a), 9 weeks (b), and 12 weeks (c) show progressive reduction of edema. a MR images show a soft fragmented callus (dashed arrow). b MR images show the callus organized and complete. It is hypertrophic, hypointense in fluid-sensitive image, and slightly heterogeneous in T1 (arrows). c MR images show a complete recovery of the tendon and peripheral musculature signal
