Utilizzo della risonanza magnetica nella diagnosi dell'edema contusivo intraosseo a livello di estremità distale dell'equino : 6 casi

Bone Marrow Edema (BME) is a recently recognized entity. MRI has provided to be most powerful tool to asses BME, as the conventional imaging technique are unable to detect trabecular injuries. “Bone bruising” describes the post-traumatic bone marrow changes demonstrated on MRI from a combination of haemorrhage, edema and microtrabecular fractures, described for the first time in the human knee in 1988. Bone bruise is a potentially important cause of orthopaedic pathology both in human and veterinary medicine, especially in sport horses. The term “bruise” indicates the traumatic origin of bone marrow changes. BME is defined as a region of hypointensity in T1 weighted sequences and hyperintensity in T2 and STIR sequences. Of 20 lame horses underwent MRI, six were included in the study, with pain localized at the fetlock region (5 cases) or hoof pain (1 case).
