Abstract：Objective To investigate the value of CT imaging omics model in the diagnosis of plantar neuropathy in diabetic foot
patients. Methods The clinical and CT imaging data of 29 diabetic patients (diabetic foot group) and 47 patients (non-diabetic foot
group) with unilateral foot trauma during the same period who were admitted to our hospital from July 2019 to December 2020
were retrospectively analyzed. Based on foot CT images, 1743 image omics features were extracted by deepwise scientific research
platform. Linear correlation between features and F-test were used for feature selection, and then Logistic regression analysis was
used to construct the model. The receiver operating characteristic (ROC) curve was used to verify the model in the training group
and the verification group, and the efficacy of imaging omics features in diagnosis of plantar nerve in diabetic foot was evaluated.
Results After feature screening, 12 imaging features were selected to construct the diagnosis model of plantar neuropathy in diabetic
foot patients. In the training group, the area under the ROC curve (AUC) was 0.97 (95%CI: 0.94-1.00), the sensitivity and specificity
were 90.20% and 89.13%, respectively, and the diagnostic accuracy of the model was 89.69%. In the verification group, the AUC
was 0.89 (95%CI: 0.82-0.95), the sensitivity and specificity were 84.31% and 80.43%, respectively, and the diagnostic accuracy of
the model was 82.47%. Conclusion The imaging group model based on foot CT images has high diagnostic efficiency for plantar
neuropathy in patients with diabetes foot
