Colorectal polyps less than 6 mm in size pose a negligible risk to the development of colorectal carcinoma. The sensitivity and specificity for detection of diminutive lesions on all available…
The primary goal of colorectal cancer screening and prevention is the detection and removal of advanced neoplasia. Computerized tomography (CT) colonography is now well established as an effective screening test….
The technical objective of computed tomographic colonography (CTC) is to acquire high-quality computed tomography images of the cleansed, well-distended colon for polyp detection. In this article the authors provide an…
The amount of data accumulated in trials of CT colonography (CTC) has greatly increased in the past decade. The information from these studies is shaping clinical practice and public health…
Traditionally, endoscopic mucosal resection and surgery were the only available treatments for large colorectal tumors, even for those detected at an early stage. The endoscopic submucosal dissection (ESD) technique, which…
Molecular imaging is a rapidly growing new discipline in gastrointestinal endoscopy that involves the development of novel imaging probes and instruments to visualize the molecular expression pattern of mucosa in…
Colorectal cancer is a heterogeneous disease arising through multiple possible pathways. Elucidating the genetic factors controlling molecular phenotype, morphology, histology, and prognosis of different tumor types continues to be a…
Until recently, 2 major forms of colorectal polyp were recognized: the adenoma and the hyperplastic polyp. Adenomas were known to represent a precursor to colorectal cancer, whereas hyperplastic polyps were…
Computed tomographic colonography (CTC) has been reported to be as effective as optical colonoscopy in the detection of significant adenomas. However, there are widely conflicting performance data in relation to…
The incidence of colorectal cancer associated with ulcerative colitis (UC) increases with time. It is imperative to identify dysplasia-associated lesions or masses (DALM) and non-polypoid colorectal neoplasms (NP-CRN) to reduce the…
