Breast Imaging

Breast imaging includes imaging modalities used for breast cancer screenings and planning therapy once cancer is detected. Mammography is the primary modality used. Mammogram technology is moving from 2D full-field digital mammography (FFDM) to breast tomosynthesis, or 3D mammography, which helps reduce false positive exams by allowing radiologists to look through the layers of tissue. Overlapping areas of dense breast tissue on 2D mammograms appear similar to cancers and 3D tomo helps determine if suspect areas are cancer or not. About 50% of women have dense breast tissue, which appears white on mammograms, the same as cancers, making diagnosis difficult. Radiologists use the Breast Imaging Reporting and Data System (BI-RADS) scoring system to define the density of breast tissue. Many states now require patients to be notified if they have dense breasts so they understand their mammograms might be suboptimal and they should use supplemental imaging that can see through the dense areas. This includes tomosythesis, breast ultrasound, automated breast ultrasound (ABUS), breast MRI, contrast enhanced mammography and nuclear imaging, including positron emission mammography (PEM).

New AI tool accurately classifies breast density

The software was trained using more than 700 images and achieved a breast density classification accuracy of 89%, experts recently shared in Radiology: Artificial Intelligence.

What routine mammograms can tell us about a woman’s CVD risk

Signs of breast arterial calcification on a patient’s routine mammogram may suggest they face a greater risk of cardiovascular disease.

Stacey Wolfson, MD, chief resident, and Beatriu Reig, MD, MPH, clinical assistant professor of radiology, Department of Radiology, NYU Grossman School of Medicine, explain the findings of a study they were the lead authors on published in Radiology. Their study looked at 1,200 women who were vaccinated and received breast imaging exams, and they found several cancers, so their conclusion is not to wait for breast imaging after receiving a COVID vaccine or booster.

Mayo Clinic offers new guidance on supplemental screening of women with dense breasts

There are not yet consensus-based guidelines available for screening women with dense breast tissue, so researchers at Mayo Clinic recently developed a set of recommendations regarding supplemental screening. 

The FDA tracks mammography systems and the number of exams performed in the U.S. through its Mammography Quality Standards Act (MQSA) program. This is an example of the GE Senobright HD imaging system.

3D mammography approaching 50% of breast imaging systems in the U.S.

The latest U.S. Food and Drug Administration data on mammography systems installed nationwide shows DBT systems are rapidly replacing traditional 2D full field digital mammography units.

FDA issues new guidance on appealing decisions that adversely impact mammography accreditation

The U.S. Food and Drug Administration detailed instructions on how breast imaging providers can appeal decisions related to their accreditation and certification. 

The most popular radiology business stories in February 2022 included several lawsuits pertaining to imaging centers and radiology companies and a new study suggesting not to delay mammograms in women who were recently vaccinated against COVID-19.

A new study suggests not delaying mammograms due to getting a COVID vaccine because cancers may go un detected. The RSNA study showed several examples of swollen lymph nodes that appeared to be from the vaccine, but turned out to be cancers.

Q&A: Should COVID vaccinated patients delay getting breast imaging — new study says no 

The lead authors of a new study, Stacey Wolfson, MD, and Beatriu Reig, MD, from the Department of Radiology, NYU Grossman School of Medicine, say women should not delay breast imaging if they recently received the COVID vaccine or a booster.
