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).

Disparities in breast cancer detection and care persist, despite a drop in mortality, new ACS report reveals

While Black women have lower incidence of breast cancer diagnosis, their mortality rates are 40% higher than those observed in white women.

Experts share positive news for women who have undergone multiple GBCA exposures during breast MRI

Authors of the new study stated that their findings are “reassuring” for both clinicians and patients.

22% of eligible young women have not undergone a mammogram yet

Also, up to 26% of eligible women have not had a formal conversation with their physician regarding their breast cancer risks, despite current guidelines that suggest these discussions start sooner rather than later.

Longitudinal changes in breast density could be linked to breast cancer risk

Researchers found that cancer risk in premenopausal women with fatty breasts at initial imaging nearly doubled if an increase in density was observed during their second and third mammograms.

This image gallery shows examples from various breast imaging modalities, including digital breast tomosynthesis, ultrasound and breast MRI, in addition to clinical presentations of breast cancer and other pathologies.

Experts describe MRI characteristics of rare breast cancer

The new paper describes the imaging characteristics of metaplastic carcinoma of the breast and correlates the findings with clinical and histopathological characteristics/diagnoses.

Scoring system outperforms BI-RADS assessments of contrast-enhanced mammography exams

For specificity—a metric that has been somewhat unpredictable in breast MRI and CEM—the scoring system performed significantly better than BI-RADS.

DBT guidance saves time, reduces exposure during breast calcification biopsy

Experts found that opting for DBT-guided biopsy of suspicious breast calcifications could shave up to five minutes off the total procedure time.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.

The newly cleared offering, AutoChamber, was designed with opportunistic screening in mind. It can evaluate many different kinds of CT images, including those originally gathered to screen patients for lung cancer. 

AI-enabled coronary plaque assessments deliver significant value, according to late-breaking data presented at TCT. These AI platforms have gained considerable momentum in recent months, receiving expanded Medicare coverage in addition to a new Category I CPT code.
