At this year's RSNA meeting, expect a lot of buzz about breast ultrasound and digital breast tomosynthesis (DBT), with everything from refresher courses to scientific sessions devoted to these technologies. But also get ready for animated discussion about how best to image dense breasts and also the pros and cons of breast cancer screening.Kick the week off at a scientific session dedicated to diagnostic breast ultrasound (Sunday, December 1, 10:45 a.m.-12:15 p.m., SSA01, Arie Crown Theater). Presenters will touch on topics that include how 3D breast ultrasound compares in terms of diagnostic yield to MRI, automated breast ultrasound's performance compared with handheld ultrasound in detecting suspicious calcifications, and whether shear-wave elastography findings can predict lymph node involvement in women with invasive breast cancer. And don't miss Sunday's refresher course on current issues in breast cancer screening (2:00 p.m.-3:30 p.m., RC115, Room S406A).
