Purpose Noninvasive diagnosis of liver fibrosis is a popular topic in the medical literature. Textural analysis on B-mode ultrasound is viewed as a noninvasive tool for fibrosis staging. A liver tissue model is proposed and used to simulate ultrasound images. Methods One hundred and twenty-five patients with chronic hepatitis C were included in this study. Patients were investigated using B-mode ultrasound and liver biopsy (Metavir scoring). A texture

This paper presents an automatic tool capable to learn from a patients data set with 24 medical indicators characterizing each sample and to subsequently use the acquired knowledge to differentiate between five degrees of liver fibrosis. The indicators represent clinical observations and the liver stiffness provided by the new, non-invasive procedure of Fibroscan. The proposed technique combines a hill climbing algorithm that selects subsets of important

One rare cause of upper gastrointestinal (GI) bleeding is represented by the evidence of blood on the papillary level during endoscopy. The differential diagnosis is made between hemobilia and hemosuccus pancreaticus caused by a tumor, hematoma or a pseudoaneurysm which communicates with the pancreatic duct. Upper GI endoscopy must be performed within 24 hours of admission. Advanced age, active bleeding, hypotension or shock, red blood cell transfusion
