MRI can assess bone changes in diabetic feet
A study published in the European Journal of Radiology has found that magnetic resonance imaging (MRI) foot examinations can evaluate bone changes and exudate levels in patients with diabetic feet.
In this retrospective study, researchers examined MRI evaluations for 90 feet looking for vascular problems (infarct and necrosis), osteomyelitis, destruction and debris, osteochondritis and dislocation. The MRIs were effective in assessing bone marrow changes and traumatic bone abnormalities, along with oedema quantities.
Of the 90 MRI evaluations, 17 presented with vascular anomalies, 11 of the cases had infarct and six had necrosis. Traumatic changes were found in 20 cases; of them, 10 had oedema viewable on MRI. Five cases had occult fractures and five had visible fractures shown on both X-ray and MRI. Bone destruction or debris was found in 11 feet, and bone dislocation was discovered the same number. There was evidence of osteochondritis in 24 cases and osteomyelitis was diagnosed in 10.
This method of assessing feet may be important for future diabetic foot assessments to prevent further complications and decrease the likelihood of amputation.
