Several studies have confirmed the advantages of the use of digital breast tomosynthesis (DBT) as an adjunct to digital mammography (DM) in population-based breast cancer screening studies. However the use of DBT in the surveillance of patients who have had breast cancer treatment has not been extensively investigated. 

This article summarizes the findings of a first prospective study of the use of DBT in addition to 2D imaging in patients with a history of
breast cancer treatment. It was found that the use of adjunct DBT in addition to DM in such patients reduced the rate of indeterminate findings
and hence unnecessary investigations compared to DM alone.

In this article, we briefly review the background to the increasing interest in the measurement of breast density and point out limitations of the current methods of
quantitative measurement of breast density using two dimensional mammography.

We describe the emergence of various three dimensional imaging methods for the quantification of breast density and present the results of the use of low dose chest computed tomography (LDCT) to measure breast density. LDCT is increasingly being used, e.g. in lung cancer screening, so the use of an already exisiting imaging data set may represent an efficient opportunity to provide quantitative 3D breast density determinations.

Current mammography procedures require compression of the breast by a compression paddle. Such procedures involve application of a certain force with generally no account being taken of the size of the breast. The process can result in various levels of pain and discomfort.

his article describes the rationale behind the development of a pressure-based compression system, i.e. one that takes into account the contact area of the
breast with the paddle. Validation studies of the new system show that the use of standardized pressure-based compression not only provides high quality images
at the same radiation dose but also significantly reduces the pain and discomfort reported by the women undergoing mammography examinations.

This article summarizes the findings of a recent survey and meta-analysis of publications on Contrast-Enhanced Spectral Mammography. 

The sensitivity of CESM was found to be high, underscoring the potential of the modality whose diagnostic performance could rival that of MRI, but with
added advantages of improved accessibility and lower cost.

The so-called Tyrer-Cuzick (or IBIS) model was developed to predict the risk of developing breast cancer, initially for women with an elevated risk

It is widely used and has now been validated in several studies, including with women at average risk attending routine breast screening [3,4].

Although children are especially vulnerable to the health risks of ionizing radiation, approximately 8 million CTs are performed on children in the USA. 

Widespread dose variation is common, particularly in non-pediatric focused facilities. In this article we present our rationale and hands-on
approach in developing and refining a toolkit aimed at helping a community hospital with pediatric CT dose reduction.
