| 1 | Automatic Detection of COVID-19 Infection Using Chest X-Ray Images Through Transfer Learning显示文摘The new coronavirus(COVID-19),declared by the World Health Organization as a pandemic,has infected more than 1 million people and killed more than 50 thousand.An infection caused by COVID-19 can develop into pneumonia,which can be detected by a chest X-ray exam and should be treated appropriately.In this work,we propose an automatic detection method for COVID-19 infection based on chest X-ray images.The datasets constructed for this study are composed of194 X-ray images of patients diagnosed with coronavirus and 194 X-ray images of healthy patients.Since few images of patients with COVID-19 are publicly available,we apply the concept of transfer learning for this task.We use different architectures of convolutional neural networks(CNNs)trained on Image Net,and adapt them to behave as feature extractors for the X-ray images.Then,the CNNs are combined with consolidated machine learning methods,such as k-Nearest Neighbor,Bayes,Random Forest,multilayer perceptron(MLP),and support vector machine(SVM).The results show that,for one of the datasets,the extractor-classifier pair with the best performance is the Mobile Net architecture with the SVM classifier using a linear kernel,which achieves an accuracy and an F1-score of 98.5%.For the other dataset,the best pair is Dense Net201 with MLP,achieving an accuracy and an F1-score of 95.6%.Thus,the proposed approach demonstrates efficiency in detecting COVID-19 in X-ray images. | Elene Firmeza Ohata Gabriel Maia Bezerra João Victor Souza das Chagas Aloísio Vieira Lira Neto Adriano Bessa Albuquerque Victor Hugo Cde Albuquerque Pedro Pedrosa Rebouças Filho | 2021 | IEEE/CAA Journal of Automatica Sinica2021，8，1： | 3 |

| 9 | Extrahepatic right hepatic duct diverticulum: a rare entity显示文摘BACKGROUND:Douglas described choledochal cysts in 1852 and Todani proposed an anatomy-based classification in 1977. The classification is the most extensively used,but does not include some rare variations.We present a case of hepatic duct diverticulum,one of the variations,and discuss its diagnosis and treatment. METHODS:A 57-year-old woman presented with upper abdominal pain and discomfort associated with nausea and vomiting.She was finally diagnosed with cholelithiasis and right hepatic duct diverticulum. RESULT:The patient underwent resection of the hepatic duct diverticulum and cholecystectomy,and was asymptomatic 26 months after surgery. CONCLUSIONS:Hepatic duct diverticulum is a rare form of choledochal cyst,not included in Todani's classification. Todani's classification including this and other uncommon variations of choledochal cysts must be reviewed.The best diagnostic imaging methods and treatment for choledochal cysts must be defined. | Eduardo SM Fernandes Raquel L Bernardo Moacir M Fernandes Rogério MC Araújo Renato Sebbe Asterio Monte JoséF Coelho Antonio AP Souza Joaquim Ribeiro Filho | 2010 | Hepatobiliary & Pancreatic Diseases International2010，9，2： | 1 |
