MR imaging of bone oedema: Mechanisms and interpretation pictorial review

Widespread use of MRI now allows the routine identification of previously unevaluated traumatic bone marrow oedema and haemorrhage. Similar marrow oedema is identified in patients with tumours, hyperaemia and medullary congestion. Patterns and extent of traumatic bone marrow oedema and haemorrhage are dictated by mechanism. Diffusion techniques may allow precise evaluation of severity of injury. Illustrative examples and discussion are presented. Eustace, S. (2001)
