A novel multi-instance learning (MIL) method is proposed to recognize liver cancer with abdominal CT images based on instance optimization (IO) and support vector machine with parameters optimized by a combination algorithm of particle swarm optimization and local optimization (CPSO-SVM). Introducing MIL into liver cancer recognition can solve the problem of multiple regions of interest classif...

a 13 years old boy with severe abdominal pain and history of intermittent (ii bleeding since the aye of 3 months, is presented. different diagnostic procedures were unremarkable. a tc-99m pertechnetate abdominal study revealed abnormal radionuclide accumulation in small bowel region. duplication of small bowel was suspected which was confirmed by surgery and pathologic examination.

Recently four phases CT has been widely used for diagnosing liver diseases, especially cancer. This paper describes an automatic method for segmenting the liver region from third phase abdominal CT. First, blood vessels in the liver are extracted with a threshold. Then morphological dilation enables us to define an approximate liver region, which is found to be very useful for removing abutting...

Peutz–Jeghers syndrome (PJS) is a rare autosomal dominant disorder. The mutation found in the serine threonine kinase (STK11)/ liver B1 (LKB1) gene on chromosome 19. It impacts 1 out of 50000–200000 individuals. Clinical menifestations include hyperpigmented lesion oral cavity, lips, fingertips and perianal region. Abdominal pain, Anaemia, Gastrointestinal (GI) bleeding, GI polyp, Intestinal ob...

137 K .M. was a 69-year-old woman who presented to her primary physician with bloating, abdominal cramping, and constipation over the previous weeks. She also noted some fullness in her right groin. She underwent an abdominal ultrasound, which revealed an adnexal mass on the right side of her abdomen, and a computed tomography (CT) scan, which demonstrated a large complex mass in the region of ...

Obesity is a fast-emerging epidemic in the Asia-Pacific region, with numbers paralleling the rising global prevalence within the past 30 years. The landscape of gut diseases in Asia has been drastically changed by obesity. In addition to more non-specific abdominal symptoms, obesity is the cause of gastro-oesophageal reflux disease, various gastrointestinal cancers (colorectal cancer, hepatocel...

dear editors: adenocarcinoma of colon and rectum is the second most common cancer of the gastrointestinal (gi) tract in children. the development of carcinoma of colon in general appears to be associated with several predisposing factors such as familial polyposis, hereditary non-polyposis syndromes, ulcerative colitis, previous ureterosigmoidostomy or radiation therapy and dietary factors (hig...
