Quantification of breast density with spectral mammography

A simple and accurate measurement of breast density is crucial for the understanding of its impact in breast cancer risk models. The feasibility to quantify volumetric breast density with a photon-counting spectral mammography system has been investigated using both computer simulations and physical phantom studies. A computer simulation model involved polyenergetic spectra from a tungsten anod...

An introduction to contrast enhanced spectral mammography

Contrast enhanced spectral mammography (CESM) is a new technology, gaining acceptance throughout Europe and the USA, but only recently introduced to the UK. GE Healthcare is currently the only UK vendor of CESM, using the brand name Senobright. In this article, we will explore the theory behind the technology and the practicalities of performing the test. A brief literature overview is provided...

Dual-energy contrast-enhanced mammography.

The degree of vascularization in breast lesions is related to their malignancy. For this reason, functional diagnostic imaging techniques have become important in recent years. Dual-energy contrast-enhanced mammography is a new, apparently promising technique in breast cancer that provides information about the degree of vascularization of the lesion in addition to the morphological information...

Spatial and spectral information in optical mammography.

This article reviews our research activities in the area of optical mammography and relates them to the historical developments and the current state and trends in the field. The guiding threads for this article are the roles played in optical mammography by spatial and spectral information. The first feature, spatial information, is limited by the diffusive nature of light propagation but can ...
