Parametric ROC curve analysis for the performance evaluation of radiological diagnosis

PAN Qing,CHEN Hui,MA Yu-jing,SHA Fei(School of Biomedical Engineering,Capital Medical University,Beijing 100069,China)  
Objective To explore the parametric ROC curve analysis for evaluating the performance of radiological diagnosis,and to present the usage of ROCKIT software.Methods Each nodule on 60 lung CT images were classified into one of the five possible classifications by two radiologists respectively.ROC curves and areas under the curves were estimated by using binormal parametric method via ROCKIT and nonparametric method via SPSS,respectively.Results Areas under ROC curves of the 2 radiologists by using ROCKIT was estimated at 0.940±0.039 and 0.785±0.075(Z=2.056,P=0.040),respectively,while areas under the curves estimated by using SPSS was 0.913±0.042 and 0.771±0.075,respectively.Smooth fitted ROC curves were drawn with ROCKIT,whereas the unsmoothed empirical ROC curves were drawn with SPSS.Conclusion Parametric estimations of the ROC curve are un-bias when the sample size of ordinal scale data is moderate,whereas the nonparametric estimations may underestimate the real values.ROCKIT software is a powerful tool for binormal parametric analysis of the ROC curve.
