The prototype of a brand new machine that may detect tumors in girls with dense breast tissue has been developed by researchers from UCL, Newcastle Hospitals and Newcastle College, in partnership with worldwide know-how group Kromek.
All breasts are composed of adipose (fatty) and fibroglandular (dense) tissue. As much as 40% of girls have dense breasts containing a excessive proportion of fibroglandular tissue.
Dense breasts pose an issue for mammogram checks, designed to detect cancerous growths. As a result of each dense tissue and tumors seem white on the mammogram, it may be troublesome to differentiate between the 2.
MRI scans are generally used to get a extra detailed scan of dense breast tissue. Whereas they’re a helpful diagnostic instrument, MRIs can take as much as an hour per scan, making it impractical for routine screening. Distinction-enhanced digital mammography (CEDM), used to focus on areas of concern within the breast exposes sufferers to larger ranges of radiation and isn’t extensively out there.
Molecular breast imaging (MBI) is one other know-how that makes use of a radioactive tracer to ‘mild up’ areas of most cancers within the breast. It has a excessive sensitivity for detecting most cancers in dense breast tissue in comparison with a regular mammogram, nonetheless the dose of radiation is larger and publicity time is longer.
The improved MBI know-how has the potential to beat these limitations by providing a diminished scan time of round ten minutes, far decrease radiation publicity, and better ranges of precision by 3D imaging.
This development wouldn’t solely lower process time considerably, but in addition present a clearer image of the place cancerous tissue is positioned with out requiring additional imaging. Collectively these enhancements imply the brand new MBI know-how could possibly be a extra environment friendly, safer and accessible resolution for supplemental screening in girls with dense breast tissue.
Round 40% of girls have dense breast tissue, however this solely turns into evident after they attend their mammogram. This isn’t normally a trigger for concern as screening with mammograms is efficient, however girls with dense breast tissue do have a barely elevated threat of getting breast most cancers.
Discovering new applied sciences that may enhance our capacity to detect breast most cancers in dense breasts is actually essential. We’re delighted with the progress we’ve got made with Kromek, Newcastle College and UCL because the venture started in 2022. Our hope is that this know-how might in the end save extra lives misplaced to breast most cancers sooner or later.”

Professor Kris Thielemans, a medical imaging physics professional from UCL Division of Drugs engaged on this venture with colleagues Dr Kjell Erlandsson and Professor Brian Hutton, mentioned: “This venture represents an essential alternative for advancing breast most cancers detection and enhancing diagnostic choices for ladies with dense breast tissue.
“By creating this imaging know-how, we’re shifting nearer to creating early detection accessible and more practical for a broader vary of sufferers. Our collaboration has made wonderful progress, and we’re hopeful that this know-how will play a key position in supporting higher well being outcomes.”
“Moreover, I consider that this novel know-how has appreciable potential for functions past breast imaging. For instance, there’s a rising want for devoted units for mind imaging with higher efficiency than what’s at the moment achievable in areas akin to most cancers and dementia therapy.”
Dr Arnab Basu, chief govt of Kromek, mentioned: “Our new molecular breast imaging know-how has the potential to avoid wasting girls’s lives by enabling earlier, sooner, extra correct detection of aggressive breast cancers, particularly in these with dense breast tissue the place standard mammography usually fails.
“With cutting-edge cadmium zinc telluride detectors and superior electronics, this know-how delivers sooner scans at a decrease dose, reworking a regular 2D picture right into a exact 3D view. Presently in prototype trials at Newcastle upon Tyne Hospitals, the system is poised to make breast most cancers screening each more practical and accessible for these most in danger.”
The venture, which has obtained £2.5m from Innovate UK, will enter scientific trials as soon as the present part of prototype testing is full.
