| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Liver biopsy currently used for a definitive diagnosis of liver fibrosis is invasive and causes inconvenience to the patient, thus non-invasive techniques are preferable. Previous works reported classification and estimation method to diagnose liver fibrosis using information of blood test only and the liver shape only acquired from CT image, respectively. The purpose of this study was to improve classification accuracy by integrating the information of shape and blood test. In this study, we built support vector machine from integrating information of shape and blood test. We performed the classification of liver fibrosis presence and evaluated area under the curve (AUC). We conducted one hundred times 3-fold cross-validation, and founded that the average AUC is shown to be 0.990±0.007. The integration of the both information further improved the AUC significantly (p<0.01). | |
