Diffusion-weighted MRI (DWI) may soon command broader consideration than it’s been getting as a supplemental breast-screening tool. The modality not only finds many breast cancers that don’t show up on mammograms but also outperformed supplemental breast ultrasound in a study published online Oct. 28 in Clinical Imaging.

The U.S. Food and Drug Administration (FDA) issued an Oct. 27 reminder that thermography is not an acceptable substitute for mammography.

Screening mammography providers “on wheels” planning to serve medically underserved Latino communities would do well to first communicate with each community on perceptions of such services and, where needed, to offer education prior to rolling in.

Following screening mammography that turns up nothing, women with dense breast tissue are much more likely to pursue additional imaging with automated breast ultrasound (ABUS) when two things happen: their radiologists inform them of their tissue density and encourage them to consider the secondary exam because of it.

Image quality in mammography, thanks to concerns about radiation dose, faces a Goldilocks problem—where radiologists want to get the best image possible, while also minimizing risk to the patient.

Even when they don’t know the exact location or nature of the problem, radiologists can tell something is not quite right with a mammogram in the blink of an eye.

 
‘Extra’ technologist training improves mammography quality

Numerous studies have shown that poor patient positioning is a common culprit when screening mammography quality is suboptimal. New research shows that technologists who get more training in positioning than is mandated tend to acquire high-quality images more consistently than those who don’t.

Molecular breast imaging shows its supplemental chops as a routine-practice tool

Molecular breast imaging (MBI) has proven a useful secondary screening tool for women with dense breasts when routinely deployed at a large, community-based breast imaging center. 

Synthesized 2D mammo emerges as a worthy low-dose screening option

Digital mammography combined with digital breast tomosynthesis is better than digital mammography alone at finding cancers and reducing recall rates. But another combo has now proven just as good at detection, better at cutting recalls and especially impressive at reducing radiation dose. 

Data-rich modeling suggests many women need breast screening only triennially

Average-risk women with low breast density who get screened for breast cancer every three years share a trait in common with higher-risk women with high breast density who get screened every year. Both groups will maintain a similar or better balance of benefits and harms than average-risk women who get screened every other year.

Tomo breast screening add-on is cost-effective, especially before 50

Adding annual screening tomosynthesis to 2D mammography beginning at age 40 is cost-effective compared with 2D mammography alone, according to a study published online Aug. 23 in the American Journal of Roentgenology. 

Consensus guideline: Wider DCIS margins don’t cut breast-cancer recurrence

An expert review panel incorporating input from three of the top national cancer organizations is recommending a 2-mm rim of healthy tissue for women with ductal carcinoma in situ (DCIS) treated with breast-conserving surgery and whole-breast radiation therapy. 

Breast cancer imaging challenge one part of achieving Cancer Moonshot

Participants in the Digital Mammography DREAM Challenge are trying to do their part to contribute to the nationwide goal of completing 10 years of cancer research in half the time. It’s funded under the Cancer Moonshot’s Coding4Cancer initiativepitting coding teams against each other in a friendly fight to see who can come up with the best way to improve mammogram readings.

 
Protein biomarkers work together to detect breast cancer

Early detection is crucial when treating breast cancerand to that end, researchers have turned to our own bodies to help. A study from Provista Diagnostics looked at two different protein biomarkers to find if they could improve early detection.

Study shows breast tumors adopt resistance to hormone therapy

Hormone therapy is a common and effective treatment for breast cancer, but some genetically complex tumors may become resistant to the treatment, according to a Washington University study.
