State of the art: iterative CT reconstruction techniques [PDF]

open access: yes, 2015
Owing to recent advances in computing power, iterative reconstruction (IR) algorithms have become a clinically viable option in computed tomographic (CT) imaging. Substantial evidence is accumulating about the advantages of IR algorithms over established

Quantifying the impact of adherence to screening strategies on colorectal cancer incidence and mortality

open access: yesCancer 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.

Using a hypothetical scenario to assess public preferences for colorectal surveillance following screening-detected, intermediate-risk adenomas: annual home-based stool test vs. triennial colonoscopy [PDF]

open access: yes, 2016
Background To assess public preferences for colorectal cancer (CRC) surveillance tests for intermediate-risk adenomas, using a hypothetical scenario. Methods Adults aged 45–54 years without CRC were identified from three General Practices in England (two

Multi-scale characterizations of colon polyps via computed tomographic colonography

open access: yesVisual 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 ...

Terminal digit preference biases polyp size measurements at endoscopy, computed tomographic colonography and histopathology [PDF]

open access: yes, 2016
BACKGROUND AND STUDY AIMS: Terminal digit preference bias for "pleasing" numbers has been described in many areas of medicine. The aim of this study was to determine whether endoscopists, radiologists, and pathologists exhibit such bias when measuring ...
