• Transverse stress fracture in the fibula shaft in a runner.

• This image demonstrates all the findings to look for in a stress fracture on MRI with.

• The Stress Fracture on MRI being the thin high signal line crossing transversely across the fibula (Pink arrow).

• The Low signal lines paralleling the cortex being Periosteal new bone formation (Green arrows).

• High Signal soft tissue changes being Soft tissue oedema and inflammation (Blue arrows).

• High Signal in the shaft being Bone marrow oedema (Yellow arrows).
