Advanced texture analysis and classification methods for the automatic diagnosis of the Hepatocellular Carcinoma
Introduction: The hepatocellular carcinoma (HCC) is the most frequent malignant liver tumor, appearing in 75% of liver cancer cases. The golden standard for HCC diagnosis is the needle biopsy, but it is invasive, dangerous. We develop non-invasive, computerized methods for the automatic and compute...

Thus, the imagistic textural model of HCC, respectively of the HCC evolution phases was defined in both supervised [1] and unsupervised manner [4]. The experiments were performed on 300 cases of HCC, and 100 cases of hemangioma, acquired with an older ultrasound machine, respectively on 13 HCC cases acquired with a new generation ultrasound machine. In the case of the supervised classification, we considered the following pairs of classes: HCC/cirrhotic parenchyma; HCC/hemangioma. Results: Our methods led to a satisfying classification accuracy, around 85%. Conclusion: Due to the textural model of HCC, both automatic and computer assisted diagnosis can be performed. We aim to increase the classification performance, in our future research. https://ami.info.umfcluj.ro/index.php/AMI/article/view/737Hepatocellular Carcinoma (HCC)Ultrasound ImagesAdvanced Texture AnalysisDeep LearningAutomatic and Computer Assisted Diagnosis |
