Abstract:
Objective To study the value of MRI in the diagnosis of diabetic foot(DF)ulcer.Methods MRI data of 29 cases with DF ulcer were analyzed retrospectively,among which 8 showed neuropathic osteoarthropathy (Charcot’s joint)on X-ray radiographs. To analyze the correlation of MRI features and MRA results of DF ulcer patients.Results All patients displayed with soft tissue cellulitis,and 1 6 cases suffered with osteomyelitis as well.8 cases were Charcot’s joint,and 2 cases were confirmed by biopsy for false positive osteomyelitis.8 cases of MRA could not meet the diagnostic requirements due to the contamination of the inferior genicular vein.There were no obvious difference among the incidence of Charcot’s joint,sinus,abscess and tenosynovitis between lower extremity artery stenosis and not(P=0.06;χ2=0.07, P=0.79;χ2=2.15,P=0.14;χ2=2.29,P=0.13),but the difference of incidence of osteomyelitis was obvious(χ2=4.88,P=0.03). Conclusion MRI can display osteomyelitis,neuropathic osteoarthropathy,cellulitis of the tissue,sinus,abscess,tenosynovitis and lower extremities arterial disease (LEAD)of the DF ulcer patients,and the incidence of osteomyelitis was associated with LEAD.
