Shape filtering for false positive reduction at computed tomography colonography [PDF]
, 2006 In this paper, we treat the problem of reducing the false positives (FP) in the automatic detection of colorectal polyps at Computer Aided Detection in Computed Tomography Colonography (CAD-CTC) as a shape-filtering task.

Annals of Gastroenterological Surgery, Volume 4, Issue 4, Page 405-412, July 2020., 2020 Abstract Aim With population aging, the number of frail patients with colorectal cancer has increased. The Clinical Frailty Scale (CFS) is a validated tool for assessing frailty, and higher scores indicate worse clinical outcomes following cardiovascular procedures.

Cancer Medicine, Volume 9, Issue 2, Page 824-836, January 2020., 2020 Although adherence to colorectal cancer screening has a substantial impact on clinical outcomes, estimating the magnitude of this impact has been challenging. This study provides a quantitative analysis of the extent to which differences in adherence rates affect clinical outcomes of different screening strategies.

A remote access CT colonography training system [PDF]
, 2007 Computed tomography colonography (CTC) is emerging as an alternative to conventional colonoscopy (CC). However CTC is not yet in widespread use due in part to the lack of suitably trained radiologists.

A statistical approach for robust polyp detection in CT colonography [PDF]
, 2005 In this paper we describe the development of a computationally efficient computer-aided detection (CAD) algorithm based on the statistical features derived from the local colonic surface that are used for the detection of colonic polyps in computed ...

Multi-scale characterizations of colon polyps via computed tomographic colonography
Visual Computing for Industry, Biomedicine, and Art, 2019 Texture features have played an essential role in the field of medical imaging for computer-aided diagnosis. The gray-level co-occurrence matrix (GLCM)-based texture descriptor has emerged to become one of the most successful feature sets for these ...

Vector textures derived from higher order derivative domains for classification of colorectal polyps
Visual Computing for Industry, Biomedicine, and Art, 2022 Textures have become widely adopted as an essential tool for lesion detection and classification through analysis of the lesion heterogeneities. In this study, higher order derivative images are being employed to combat the challenge of the poor contrast

Robotic Colonoscopy and Beyond: Insights into Modern Lower Gastrointestinal Endoscopy
Diagnostics, 2023 Lower gastrointestinal endoscopy is considered the gold standard for the diagnosis and removal of colonic polyps. Delays in colonoscopy following a positive fecal immunochemical test increase the likelihood of advanced adenomas and colorectal cancer (CRC)
