    Could ultrasound be the primary screening test for breast cancer? Is the public served by the increasing use of handheld ultrasound? These questions and many more will be addressed at the upcoming RSNA meeting in Chicago.

    On Sunday, November 25, RSNA attendees can check out a scientific session all about breast ultrasound -- both cancer diagnosis and screening (10:45 a.m.-12:15 p.m., SSA01, Arie Crown Theater). There's also a session on physics research that ranges from exploring the use of contrast-enhanced ultrasound to monitor cancer treatment response to quantifying prostate motion during transrectal ultrasound imaging (10:45 a.m.-12:15 p.m., SSA21, Room S405AB).

    On Sunday afternoon, ultrasound practitioners will want to take advantage of a refresher course on 3D imaging topics in women's health (2:00 p.m.-3:30 p.m., RC110, Room S403A), or a workshop about techniques for interventional sonography and thermal ablation (2:00 p.m.-3:30 p.m., RC152, Room E264).

    Road to RSNA 2012: Ultrasound Preview Monday, November 26, will bring an array of refresher courses, from ultrasound diagnosis and management of adnexal cystic masses (8:30 a.m.-10:00 a.m., RC210, Room N226) to a master class in musculoskeletal ultrasound (8:30 a.m.-10:00 a.m., RC231, Room E258). Also that morning, a gastrointestinal series will offer an overview of advances in hepatic imaging (8:30 a.m.-12:00 p.m., VSGI21, N227), while in the afternoon, RSNA attendees can check out a scientific paper session devoted to genitourinary imaging of the pregnant patient (3:00 p.m.-4:00 p.m., SSE10, Room E353B).

    On Tuesday, November 27, don't miss the musculoskeletal ultrasound series (8:30 a.m.-12:00 p.m., VSMK31, Room E450A). An afternoon scientific session will explore breast ultrasound topics, such as how automated breast ultrasound performs diagnostically and whether triple-negative breast cancer manifests certain ultrasound characteristics (3:00 p.m.-4:00 p.m., SSJ01, Arie Crown Theater).

    On Wednesday, November 28, RSNA attendees can explore a multisession course on the essentials of ultrasound, including imaging the gallbladder and bile ducts, thyroid sonography, and carotid ultrasound (8:30 a.m.-10:00 a.m., MSES41, Room S100AB). Refresher courses on Wednesday morning will highlight topics such as hematuria and flank pain (8:30 a.m.-10:00 a.m., RC507, Room E353B), clinical ultrasound technology (8:30 a.m.-10:00 a.m., RC510, Room N229), and ultrasound for thyroid cancer (8:30 a.m.-10:00 a.m., RC531, Room E352).

    Also on Wednesday, be sure to check out a "controversy session" during which a panel that includes experts from radiology, emergency medicine, and industry will discuss whether handheld ultrasound is a threat to radiology (4:30 p.m.-6:00 p.m., SPSC41, Room S404CD).

    What's happening on Thursday, November 29? Take a new look at an old topic -- ultrasound of the bowel -- at a morning refresher course (8:30 a.m.-10:00 a.m., RC610, Room S405AB). In the afternoon, RSNA attendees can check out a "hot topic" session on imaging evaluation of inflammatory arthritis (3:00 p.m.-4:00 p.m., SPSH52, Room E451B) or avail themselves of one of a number of refresher courses, from adrenal imaging (4:30 p.m.-6:00 p.m., RC707, Room E353B), to mistakes to avoid in obstetric ultrasound (4:30 p.m.-6:00 p.m., RC710, Room E451B), to real-time interventional ultrasound (4:30 p.m.-6:00 p.m., RC752, Room E264).

    On Friday, November 30, courses will include abdominal ultrasound case studies (8:30 a.m.-10:00 a.m., RC810, Room S402AB), breast ultrasound (8:30 a.m.-10:00 a.m., RC815, Room E451B), or a workshop on ultrasound-guided breast procedures (8:30 a.m.-10:00 a.m., RC852, Room E264).
