Association Between Visceral Adiposity and Colorectal Polyps on CT Colonography

Associations among Pericolonic Fat, Visceral Fat, and Colorectal Polyps on CT Colonography

OBJECTIVE To determine the association between pericolonic fat and colorectal polyps using CT colonography (CTC). METHODS A total of 1169 patients who underwent CTC and optical colonoscopy on the same day were assessed. Pericolonic fat was measured on CTC in a band surrounding the colon. Visceral adipose tissue volume was measured at the L2-L3 levels. Student's t-tests, odds ratio, logistic r...

CT colonography and colorectal screening.

Automated synthesis, insertion and detection of polyps for CT colonography

CT Colonography (CTC) is a new non-invasive colon imaging technique which has the potential to replace conventional colonoscopy for colorectal cancer screening. A novel system which facilitates automated detection of colorectal polyps at CTC is introduced. As exhaustive testing of such a system using real patient data is not feasible, more complete testing is achieved through synthesis of artif...

Segmentation and Size Measurement of Polyps in CT Colonography

Virtual colonoscopy is a relatively new method for the detection of colonic polyps. Their size, which is measured from reformatted CT images, mainly determines diagnosis. We present an automatic method for measuring the polyp size. The method is based on a robust segmentation method that grows a surface patch over the entire polyp surface starting from a seed. Projection of the patch points alo...

Association between Blood Mercury Level and Visceral Adiposity in Adults

BACKGROUND Few studies have examined the association between mercury exposure and obesity. The aim of this study is to investigate the association between blood mercury concentrations and indices of obesity in adults. METHODS A total of 200 healthy subjects, aged 30 to 64 years, who had no history of cardiovascular or malignant disease, were examined. Anthropometric and various biochemical pr...
