Computed tomography colonography compared with conventional colonoscopy for the detection of colorectal polyps.
OBJECTIVE To determine the diagnostic accuracy of computed tomography colonography (CTC) compared with conventional colonoscopy (CC). METHODS Patients with an indication of CC were included. Fifty patients underwent CTC using multidetector CT before diagnostic colonoscopy was performed by an expert colonoscopist. Diagnostic accuracy was assessed individually both for each polyp and for each p...
متن کاملComparison of multidetector computed tomographic colonography and conventional colonoscopy for detection of colorectal polyps and cancer.
BACKGROUND Computed tomographic colonography (CTC) is a new technique for detecting colonic neoplasms. Data on the utility of this method in the Indian population are limited. METHODS Forty-two patients with symptoms of colonic disease underwent CTC and conventional colonoscopy (CC) within one week of each other and the findings at these two investigations were compared. RESULTS The entire ...
متن کاملComputed tomographic colonography (virtual colonoscopy): a multicenter comparison with standard colonoscopy for detection of colorectal neoplasia.
CONTEXT Conventional colonoscopy is the best available method for detection of colorectal cancer; however, it is invasive and not without risk. Computed tomographic colonography (CTC), also known as virtual colonoscopy, has been reported to be reasonably accurate in the diagnosis of colorectal neoplasia in studies performed at expert centers. OBJECTIVE To assess the accuracy of CTC in a large...
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 کاملComparison of 64-Detector CT Colonography and Conventional Colonoscopy in the Detection of Colorectal Lesions
BACKGROUND Colon cancer is a leading cause of morbidity and mortality in developed countries. The early detection of colorectal cancer using screening programs is important for managing early-stage colorectal cancers and polyps. Modalities that allow examination of the entire colon are conventional colonoscopy, double contrast barium enema examination and multi-detector computed tomography (MDC...
