Healing is monitored by assessment of fracture gap, margins, degree of displacement, periosteal proliferation and degree of mineralization along with the changes in associated bone marrow signal. The persistence of increased bone marrow signal intensity is not a clear indicator of a lack of progression (healing) since it is known that STIR hyperintensity can persist despite resolution of lameness. Furthermore, mature fibrous tissue as seen in delayed or non‐union fractures can have mixed T2 signal but is generally T1 hyperintense, making the degree of mineralization difficult to assess.

Bone stress injuries in humans have been graded according to MRI features of the periosteal surface, bone marrow and the presence of a fracture line. Depending on anatomical location, these can be used to develop management strategies and return to exercise [144].
