CT colonography in detection of colorectal carcinoma
BACKGROUND Diagnostic methods used in screening and detecting colorectal carcinoma are digitorectal examination, faecal occult blood testing, sigmoidoscopy, DNA stool analysis, barium enema, colonoscopy, and as of recently CT colonography. The aim of this study was to establish diagnostic accuracy and comfort of CT colonography compared to colonoscopy and barium enema. PATIENTS AND METHODS We...
متن کاملDiagnostic Performance of CT Colonography for the Detection of Colorectal Polyps
OBJECTIVE To investigate the diagnostic value of CT colonography for the detection of colorectal polyps. MATERIALS AND METHODS From December 2004 to December 2005, 399 patients underwent CT colonography and follow-up conventional colonoscopy. We excluded cases of advanced colorectal cancer. We retrospectively analyzed the CT colonography findings and follow-up conventional colonoscopy finding...
متن کاملAutomated 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...
متن کاملComputer Aided Detection of Polyps in CT Colonography
PURPOSE A massive-training artificial neural network (MTANN) has been developed for the reduction of false positives (FPs) in computer-aided detection (CADe) of polyps in CT colonography (CTC). A major limitation of the MTANN is the long training time. To address this issue, the authors investigated the feasibility of two state-of-the-art regression models, namely, support vector regression (SV...
