Road to RSNA 2015: Women's Imaging Preview

By Kate Madden Yee, staff writer
November 11, 2015

Women's imaging is a crucial part of healthcare around the world, and it is particularly unique because it makes use of such a variety of modalities. This fact will be obvious to RSNA 2015 attendees, as researchers discuss topics ranging from ways to use abbreviated MR protocols in high-risk screening programs to using dedicated breast CT for imaging microcalcifications.

A key highlight at the meeting will be digital breast tomosynthesis (DBT) research, with studies that explore how the technology has been performing in screening settings over the past few years, how synthetic 2D plus DBT compares to the combination of conventional mammography and tomosynthesis, and how radiologists are using the technology in diagnostic breast imaging applications.

As well, attendees can expect to hear many studies focused on breast ultrasound, with papers on using contrast with the modality, how ultrasound can help clinicians predict breast tumor response to neoadjuvant chemotherapy, and what features to look for on ultrasound for breast cancers that are positive for the estrogen receptor.

Finally, if you like refresher courses, the meeting will not disappoint. RSNA 2015 is hosting a variety of these sessions, including two "hot topic" gatherings -- one centered on ultrasound and tomosynthesis and the other on breast cancer screening -- as well as courses on MR-guided breast biopsy, ultrasound-guided interventional breast procedures, and the biology of breast cancer, to name a few.

For highlights of just some of the many women's imaging research papers and posters scheduled for presentation at this year's meeting, read on. To view RSNA's complete listing of abstracts for the 2015 scientific and educational program, click here.

Breast CT tops mammography for microcalcifications
Sunday, November 29 | 11:55 a.m.-12:05 p.m. | SSA20-08 | Room S404AB
High-resolution breast CT improves the assessment of 3D microcalcification clusters, addressing one of mammography's limitations: the superimposition of tissue, according to researchers from Germany.
Dedicated breast CT offers promise as mammography adjunct
Sunday, November 29 | 12:05 p.m.-12:15 p.m. | SSA01-09 | Arie Crown Theater
Dedicated breast CT shows promise as an adjunct to mammography -- with the added benefit of not requiring compression, according to research to be presented on Sunday afternoon.
