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).

AI tool's supplemental MRI recs help detect 4 times more breast cancers than density measures

What’s more, many of the cancers detected were invasive or multifocal, making their detection more timely.

Changes in AI-based risk scores identify women at greatest risk of developing breast cancer

The more an individual’s score changes, the greater the odds are of them being diagnosed with cancer in the near future, new research presented at SIIM 2024 suggests.

Applying Node-RADS to breast MRI exams improves staging

The scoring system has shown great utility in predicting lymph node invasion in various cancers, but until recently, its use in patients with breast cancer had not been thoroughly explored.

3 more states pass legislation bolstering breast imaging coverage

New Hampshire is one of the latest after Republican Gov. Chris Sununu signed House Bill 1296 into law May 31, eliminating OOP expenses for supplemental services.

AI decision support tool used in breast cancer screening

Commercially available AI reduces radiologists' workload by 34% in certain screening settings

It also increases cancer detection rates and reduces false positives, according to new work published in the journal Radiology.

DBT exams take twice as long to read as 2D mammograms, but the learning curve is short

Although DBT exams are proven to identify more difficult to detect cancers, especially among women with dense breasts, they also include significantly more images than standard 2D mammograms.

Dozens of injuries trigger FDA recall of over 50,000 implantable tissue marking devices

The Class I recall, which is the most serious recall the FDA issues, comes after numerous adverse events and complications linked to the radiographic markers were reported.

Age, race and density status influence AI performance on mammogram reads

Although studies have shown AI to be effective as a support tool, several have also highlighted issues related to the potential for bias in algorithms that have not been trained on diverse datasets.
