Journal Article
Nightingale, J., Murphy, F., Robinson, L., Newton-Hughes, A., & Hogg, P. (2015). Breast compression - an exploration of problem solving and decision making in mammography. Radiography, 21(4), 364-369. https://doi.org/10.1016/j.radi.2014.11.004

Objective: Breast compression decreases radiation dose and reduces potential for motion and geometric unsharpness, yet there is variability in applied compression force within and between some centres. This article explores the problem solving proces... Read More about Breast compression - an exploration of problem solving and decision making in mammography.
