Visual phrase learning and its application in computed tomographic colonography. [PDF]

Med Image Comput Comput Assist Interv, 2013
In this work, we propose a visual phrase learning scheme to learn an optimal visual composite of anatomical components/parts from CT colonography images for computer-aided detection. The key idea is to utilize the anatomical parts of human body from medical images and associate them with biological targets of interest (organs, cancers, lesions, etc ...

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

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.
