Real-time detection of colon polyps during colonoscopy using deep learning: systematic validation with four independent datasets

Scientific Reports, 2020
We developed and validated a deep-learning algorithm for polyp detection. We used a YOLOv2 to develop the algorithm for automatic polyp detection on 8,075 images (503 polyps).

Computer-assisted polyp matching between optical colonoscopy and CT colonography: a phantom study

, 2015
Potentially precancerous polyps detected with CT colonography (CTC) need to be removed subsequently, using an optical colonoscope (OC). Due to large colonic deformations induced by the colonoscope, even very experienced colonoscopists find it difficult ...

Molecular Features of the Serrated Pathway to Colorectal Cancer: Current Knowledge and Future Directions

Gut and Liver, 2021
Serrated lesions are the precursor lesions of a new model of colorectal carcinogenesis. From a molecular standpoint, the serrated pathway is thought to be responsible for up to 30% of all colorectal cancer cases.

Development of a synthetic phantom for the selection of optimal scanning parameters in CAD-CT colonography [PDF]

, 2006
The aim of this paper is to present the development of a synthetic phantom that can be used for the selection of optimal scanning parameters in computed tomography (CT) colonography. In this paper we attempt to evaluate the influence of the main scanning

Screening Relevance of Sessile Serrated Polyps [PDF]

, 2019
Conventional adenomas have historically been considered to be the only screening-relevant colorectal cancer (CRC) precursor lesion. The prevailing paradigm was that most CRCs arise along the chromosomal instability pathway, where adenomas accumulate ...
