What's the most effective way to treat uterine fibroids? Can sonography help clinicians assess appendices that are borderline in terms of size for appendicitis? And does ultrasound have prognostic value for assessing muscle strain injuries? These questions and many more will be addressed at the upcoming RSNA 2013 in Chicago.

On Sunday, December 1, RSNA attendees can check out a scientific session all about breast ultrasound -- for 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 shear-wave elastography to assess tendon damage to using dynamic contrast-enhanced ultrasound to evaluate tumor vasculature (10:45 a.m.-12:15 p.m., SSA21, Room S405AB).

Sunday afternoon, the RSNA is offering a number of refresher courses, including one focused on renal ultrasound and Doppler (2:00 p.m.-3:30 p.m., RC110, Room E450B) and another concentrated on techniques for interventional sonography and thermal ablation (2:00 p.m.-3:30 p.m., RC152, Room E264).

Monday will bring even more refresher courses, from first-trimester ultrasound (8:30 a.m.-10:00 a.m., RC210, Room S405AB) to a master class in musculoskeletal ultrasound (8:30 a.m.-10:00 a.m., RC231, Room E258). Also that morning, attendees can explore ultrasound-guided interventional breast procedures (8:30 a.m.-10:00 a.m., RC252, Room E264).

On Tuesday, December 3, don't miss a controversy session that will address the question of whether uterine artery embolization or focused ultrasound is more effective for treating fibroids (7:15 a.m.-8:15 a.m., SPSC30, Room E350). Or check out refresher courses focused on MR-guided high-intensity ultrasound (8:30 a.m.-10:00 a.m., RC317, Room S504CD) or Doppler ultrasound for visceral, extremity, and carotid applications (8:30 a.m.-10:00 a.m., RC352, Room E264).

Also Tuesday morning, RSNA conference attendees can learn about musculoskeletal ultrasound during a scientific session that will cover topics such as using the technology to assess the rotator cable to dynamic ultrasonography of the shoulder to the prognostic value of ultrasound for assessing muscle strain injuries (8:30 a.m.-12:00 p.m., VSMK31, Room E451B).

Wednesday's offerings will include refresher courses on small parts interventional ultrasound (8:30 a.m.-10:00 a.m., RC531, Room E263) and nerve ultrasound in the shoulder and neck (8:30 a.m.-10:00 a.m., RC552, Room E264). But don't miss afternoon scientific sessions on multimodality breast imaging -- including ultrasound, of course (3:00 p.m.-4:00 p.m., SSM02, Room E451A) -- and vascular and interventional ultrasound, which will explore topics such as whether the technology can be used as a prophylactic screening tool for venous thromboembolism in high-risk patients, and how contrast-enhanced ultrasound compares to multislice CT for detecting endoleaks after endovascular aneurysm repair (3:00 p.m.-4:00 p.m., SSM24, Room E450B).

What's happening on Thursday, December 5? Get updates from the experts on kidney, gynecologic, and testicular ultrasound at a morning refresher course (8:30 a.m.-10:00 a.m., RC607, Room N228) or dynamic musculoskeletal ultrasound of the lower extremity (8:30 a.m.-10:00 a.m., RC652, Room E264). Scientific sessions on Thursday include ultrasound breast screening (10:30 a.m.-12:00 p.m., SSQ01, Arie Crown Theater) and emergency radiology, particularly abdominal emergencies (10:30 a.m.-12:00 p.m., SSQ05, Room N226).

To wrap up the meeting, on Friday the RSNA will present refresher courses on using ultrasound to image focal liver lesions and gallbladder and biliary disease (8:30 a.m.-10:00 a.m., RC810, Room E351) and also thyroid cancer (8:30 a.m.-10:00 a.m., RC831, Room E450B), as well as a workshop on pediatric neurosonography (8:30 a.m.-10:00 a.m., RC851, Room E261).
