RSNA 2017 Women's Imaging Preview

Road to RSNA 2017: Women's Imaging Preview

By Kate Madden Yee, staff writer
October 31, 2017

Scientific sessions in women's imaging at RSNA 2017 will range from classic research on the effectiveness of breast cancer screening to cutting-edge studies on the use of advanced technologies such as deep learning to improve breast cancer detection.

As has been the case in the past several years, there will be a number of studies on digital breast tomosynthesis (DBT), which has become increasingly accepted for both screening and diagnostic use. Look for research that explores the technology from a range of angles, including its performance in catching smaller cancers, a new DBT technique that reduces compression without compromising image quality, and whether DBT is being used to its full potential in the Medicare population.

As for ultrasound, you'll find sessions that investigate topics such as how the technology's breast cancer detection rate compares with DBT and mammography, whether technologist-performed screening ultrasound scans in women with dense tissue lead to more recalls, and using real-time breast ultrasound to avert biopsy.

And don't forget about breast MRI, the powerful modality that's showing its potential, particularly for screening high-risk women. Speakers at RSNA 2017 will present talks on which women might benefit most from this exam, as well as new deep learning techniques for analyzing breast MRI data.

Make sure to check out the "hot topic" and "controversy" sessions on offer for women's imaging at RSNA 2017, including talks on the efficacy of abbreviated breast MRI, the ongoing controversy over mammography screening, and ultrasound for pelvic imaging. And if you need to review the basics, refresher courses will cover everything from emerging MRI technology and gynecologic ultrasound to the economics of women's imaging.

For an even deeper dive into the use of informatics-based technologies for guiding women's imaging, be sure to check back for our Road to RSNA Women's Informatics Preview next week.
