Abstract:
Objective To investigate the value of conventional radiological features and CT radiomics model to differentiate pleo-morphic adenoma(PA)from basal cell adenoma(BCA).Methods The imaging data of 97 cases of PA and 40 cases of BCA were analyzed.All patients were divided into a training set(95 cases)and a validation set(42 cases)at a ratio of 7∶3.Radiomics features were extracted and selected from CT enhancement(venous phase)imagings,and a radiomics model was established.Conventional radiological fea-tures were analyzed and a radiological model was established.The DeLong test was used to compare the differences between the two models,and the superior model was combined with clinical data to establish a joint model and plot a nomogram.Results The area under the curve(AUC)of the radiological model training set and validation set were 0.631[95％confidence interval(CI)0.546-0.716]and 0.661(95％CI 0.545-0.776),respectively.The AUC of the radiomics model training set and validation set were 0.903(95％CI 0.837-0.969)and 0.866(95％CI 0.751-0.973),respectively.The DeLong test showed that the radiomics model was superior to the radiological model(P＜0.05).The diagnostic efficacy of the joint model was further improved,with higher clinical benefits.Conclusion The CT radiomics model is superior to the conventional radiological model,and the joint model can accurately identify distinguish PA from BCA,aiding in clinical decision-making.
