Study finds higher breast recall rates in U.S. vs. Denmark May 27, 2015 -- New evidence has shown that women screened for breast cancer in the U.S. were recalled for workup much more frequently than women screened in Denmark, and cancer detection rates also varied significantly, according to a study published by the International Journal of Cancer.
New breast tomo CAD shows high sensitivity May 26, 2015 -- A new computer-aided detection (CAD) algorithm for digital breast tomosynthesis studies delivers high sensitivity and an acceptably low false-positive rate, according to Italian researchers. In a retrospective study of nearly 200 women who underwent DBT for breast cancer screening, CAD demonstrated sensitivity of 89% with a false-positive rate of 2.7 per breast.
CTC CAD boosts readers' attention -- but to what effect? May 25, 2015 -- The use of computer-aided detection (CAD) significantly alters the search and identification of polyps among readers of CT colonography (CTC) data, according to a new study in the June issue of European Radiology. In particular, CAD drew radiologists' attention to polyps more quickly, but it also prompted them to spend more time interpreting scans.
Transfer learning speeds image segmentation May 22, 2015 -- The development of automated image segmentation schemes can be enhanced significantly with the application of a process called transfer learning, according to a new Dutch study published in the May edition of IEEE Transactions on Medical Imaging.
