The Value of CT Combined with MRI in Early Diagnosis of Bone and Vascular Changes in Diabetes Foot
Objective:To explore the diagnostic value of computed tomography(CT)combined with magnetic resonance imaging(MRI)in the early stage of bone and vascular changes in diabetes foot.Methods:The 102 patients with diabetic foot treated in our hospital from January 2021 to May 2023 were examined by CT and MRI,and the results of digital subtraction angiography(DSA)were the"gold standard"to compare the detection of CT and MRI on the diagnosis of diabetic foot bone and vascular changes.Results:The detection rate of CT and MRI for bone destruction,osteoporosis,soft tissue lesions and pathological fractures was higher than CT and MRI(P＜0.05).Among 1408 segments of blood vessels,DSA detected 560 segments of stenosis and 848 segments of no stenosis;The joint detection detected 552 segments of stenosis,while 856 segments showed no stenosis,which was consistent with the"gold standard"(Kappa=0.960)and better than CT and MRI detection alone(Kappa values of 0.810 and 0.860,respectively);The accuracy,sensitivity and specificity of combined detection for the diagnosis of lower limb vascular stenosis in patients with diabetes foot were higher than that of CT and MRI alone,and the rate of missed diagnosis and misdiagnosis was lower than that of single detection,with a statistically significant difference(P＜0.05).The combined test was more accurate in detecting the degree of lower limb vascular stenosis in diabetic foot patients than CT and MRI alone(P＜0.05).Conclusion:The combined detection of CT and MRI can improve the detection rate of osteopathy in patients with diabetes foot.At the same time,the diagnosis results of lower limb vascular stenosis are more consistent with the gold standard,which can improve the diagnostic efficiency.Moreover,the combined detection has higher accuracy in the diagnosis of the degree of lower limb vascular stenosis,which can improve the diagnostic efficiency,and the combined detection has higher accuracy in the diagnosis of lower limb vascular stenosis.
