Elevated mammographic density (MD) is a significant independent risk factor for breast cancer and a source of masking in X-ray mammography. Availability of a low-cost, non-ionising measurement technique for quantitative assessment of MD would be valuable both in therapeutic and research contexts. We demonstrate that Portable NMR, a low-cost technique based on the same physics as MRI, represents a reliable approach to quantification of MD in excised breast tissue samples in vitro. We also present the initial results of an observational trial in healthy volunteers, which show that Portable NMR has a great potential for quantification of MD in vivo.
