Standardized reporting categorizes breast cancer detection methods
A standardized detection reporting system can help radiologists accurately categorize how breast cancer is identified -- either through screening or symptomatic presentation -- when performing image-guided breast biopsies, researchers have found.
Alan Zhu from the Mayo Clinic in Phoenix, AZ, and colleagues determined that such a system led to high reporting accuracy at a sustained rate that improved over time. Their study results were published January 2 in the Journal of the American College of Radiology.
“By implementing method of detection reporting systems, forwarding data to cancer registries, and tracking long-te...

RadNet testing three retail in-store breast cancer screening operations
RadNet executives will spend the next 18 months learning what does and doesn't work for operating small in-store retail breast cancer screening clinics in three areas of the U.S.
In early December 2023, the first of RadNet's three pilot MammogramNow clinics opened in a Walmart Supercenter in Milford, DE. Two more screening clinics are planned to open in 2024 in Walmart: one in Phoenix, AZ, the other in Hanford, CA, according to the company.
Tim Merchant, national director of screening networks and population health strategy for RadNet, said the Delaware location expands RadNet's statewide breast cancer screening network ...

Researchers invent elastic x-ray shield
A group in Japan has developed and tested an elastic x-ray shield made by embedding bismite particles in porous polyurethane, and suggests the new shielding material could provide more comfortable radiation protection.“It is expected that this x-ray shielding material will lead to the development of various radiation protectors used for clinical applications,” wrote corresponding author Hiroaki Hayashi, PhD, of Kanazawa University in Kanazawa, in a study published December 16 in Medical Physics.Hospitals have guidelines on the use of radiation protective procedures, and various x-ray shields are used to reduce unwanted...

Volpara touts breast density, mammography studies
Volpara Health Technologies is highlighting two peer-reviewed studies published during RSNA 2023 that featured the company's technology.One study published in Medical Physics highlighted a model and methodology for international harmonization of mammography dose estimates. The model replaces assumptions of a homogeneous breast with a more representative fibroglandular tissue distribution and shifts to the use of percentage volumetric breast density, the company said. This aligns with a clinically implemented breast composition metric.The study used Volpara's TruDensity algorithm to provide estimates of volumetric breast d...

DBT surveillance screening after breast cancer treatment effective
Surveillance screening via digital breast tomosynthesis (DBT) immediately after breast cancer treatment is effective, a study published on December 20 in the American Journal of Roentgenology reported. Researchers led by Dan Do from Massachusetts General Hospital reported that while the abnormal interpretation rate was higher during the year after diagnosis compared to subsequent years, it remained at less than 10% in all years of their six-year study.“The results support the study institution’s protocol for patients with a prior breast cancer diagnosis of returning immediately to screening mammography with DBT and c...

Koning to expand breast CT device installations in 2024
Koning Health has finalized a deal with venture firm Gentle Scan Health to support the installation of 20 of its Vera Breast CT devices across the U.S. in 2024.Under a strategic partnership, inaugural installations are scheduled for the metropolitan New York City area, Atlanta, and Southern California at the start of the year, Koning said. Koning received clearance from the U.S. Food and Drug Administration in 2017 to market Vera Breast CT devices for diagnostic mammography use. The system does not require breast compression.An illustration of a patient positioned on a Koning Vera Breast CT scanner. Image courtesy of Ko...

New AI training strategies stiffen defense against adversarial attacks
Methods for training artificial intelligence (AI) diagnostic algorithms can help prevent these models from producing medical errors caused by adversarial attacks, according to research presented at RSNA 2023 in Chicago. A test of two security techniques developed at the University of Pittsburgh suggested that efforts to make medical machine-learning diagnosis models resilient to attacks could improve patient safety and prevent fraud. The work presented at RSNA builds on previous research that investigated the feasibility of adversarial attacking (black-box type), in which data generated by generative adversarial networks (...

Safety net hospital provides equitable care in breast screening
Safety net hospitals provide equitable care in breast cancer screening in terms of race and ethnicity, a study published December 12 in Academic Radiology found. Researchers led by Alexander Boyko, MD, from Boston Medical Center in Massachusetts also found that breast cancer diagnosed at advanced stages were tied to higher mortality and lower odds of undergoing screening mammography in a safety net population. “Given no racial or ethnic differences in mortality, the safety net infrastructure at our institution effectively provides equitable cancer care once a cancer is confirmed,” Boyko and co-authors wrote. Despi...

Benign breast disease found on percutaneous biopsy ups cancer risk
Benign breast disease diagnosed through percutaneous biopsy increases the overall risk of developing breast cancer, according to research published December 13 in JAMA Surgery. A team led by Dr. Mark Sherman from the Mayo Clinic in Jacksonville, FL, found that presence of the disease on percutaneous biopsy is tied to a similar degree of increased breast cancer risk compared with surgically diagnosed benign breast disease. It also reported that the risks of both invasive breast cancer and ductal carcinoma in situ (DCIS) remained elevated among patients with the disease compared with the general population. “The finding...
