Computer-aided polyp detection aims to improve the accuracy of the colonography interpretation. The computer searches the colonic wall to look for polyplike protrusions and presents a list of suspicious areas…
New diagnostic technologies can visualize colon polyps, but not remove them. There is clear consensus that polyps 10 mm or larger need to be removed. There is still controversy surrounding…
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 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 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 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…
