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

Registration of the endoluminal surfaces of the colon derived from prone and supine CT colonography [PDF]

, 2011
Purpose: Computed tomographic (CT) colonography is a relatively new technique for detecting bowel cancer or potentially precancerous polyps. CT scanning is combined with three-dimensional (3D) image reconstruction to produce a virtual endoluminal ...

Efficacy of CO₂ Infusion for Preoperative Computed Tomographic Angiography with Computed Tomographic Colonography

Medical Science Monitor, 2021
BACKGROUND Computed tomographic colonography (CTC) is useful for patients for whom colonoscopy may be difficult to perform and is widely employed to examine the vasculature prior to colorectal cancer surgery. Computed tomographic angiography (CTA) was shown to be beneficial intraoperatively to manipulate blood vessels and prevent vascular injury. Three-

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)

Burden of waiting for surveillance CT colonography in patients with screen-detected 6–9 mm polyps [PDF]

, 2016
Purpose: We assessed the burden of waiting for surveillance CT colonography (CTC) performed in patients having 6–9 mm colorectal polyps on primary screening CTC. Additionally, we compared the burden of primary and surveillance CTC. Materials and methods:

Colorectal Cancer Screening: Tests, Strategies, and Perspectives [PDF]

, 2014
Screening has a central role in colorectal cancer (CRC) control. Different screening tests are effective in reducing CRC-specific mortality. Influence on cancer incidence depends on test sensitivity for pre-malignant lesions, ranging from almost no ...
