Discriminating dysplasia: Optical tomographic texture analysis of colorectal polyps
Optical projection tomography enables 3-D imaging of colorectal polyps at resolutions of 5-10 µm. This paper investigates the ability of image analysis based on 3-D texture features to discriminate diagnostic levels of dysplastic change from such images, specifically, low-grade dysplasia, high-grade dysplasia and invasive cancer. We build a patch-based recognition system and evaluate both multi...
متن کاملInterobserver Agreement in Assessing Dysplasia in Colorectal Adenomatous Polyps: A Multicentric Iranian Study
Background & Objective: Most colorectal cancers (CRCs) arise from adenomatous polyps, and clinical management of this type of polyp is highly dependent on the reliability and validity of the pathological diagnosis. The aim of this study was to examine the interobserver agreement of five pathologists in assessing dysplasia in adenomatous polyps. Methods: I...
متن کاملMalignant Colorectal Polyps; Pathological Consideration (A review)
Background: Routine screening colonoscopy is on the rise and pathologists have to deal with the ever larger numbers of excised colonic polyps. It is very important to optimize the patients’ individual treatment and further surveillance. Pathologists play a critical role in management, as most of the clinical decisions concerning colonic polyp managemen...
متن کاملOptical diagnosis of malignant colorectal polyps: is it feasible?
BACKGROUND AND STUDY AIMS As colorectal cancer screening programs are being implemented worldwide, an increasing number of early (T1) cancers are being diagnosed. These cancers should be recognized during colonoscopy because they require a specific therapeutic approach. Several studies have shown that Asian experts can reliably recognize T1 cancers during colonoscopy. In daily practice, however...
متن کاملAccuracy for optical diagnosis of colorectal polyps in clinical practice.
BACKGROUND Optical diagnostic involves predicting polyp histopathology from its endoscopic characteristics. It is only recommended for diminutive polyps ( < or = 5 mm) and for predictions made with high confidence. OBJECTIVES To evaluate the accuracy of optical imaging in clinical practice and to assess if optical diagnosis is useful for predicting future colonoscopy surveillance intervals wi...
