Overview of CT colonography

Abstract

Colorectal cancer is associated with high mortality and morbidity and is currently the second leading cause of cancer-related deaths in the United States. Early detection and treatment of colorectal carcinoma can significantly improve the prognosis. Although optical colonoscopy has been the gold standard for the diagnosis of this condition, computed tomography colonoscopy is increasingly playing an important role in the diagnosis and staging of colorectal carcinoma.
