Dear AuntMinnie Member,

Which is better for shoulder imaging: ultrasound or MR? What are the latest advances in musculoskeletal tumor ablation, and where does ultrasound fit in? And what is O-mode imaging, anyway?

Researchers will address these questions and many more at the upcoming RSNA 2014 meeting in Chicago.

A prominent theme at this year's meeting will be the use of ultrasound in combination with other modalities -- or on its own -- as a less-invasive, lower-cost alternative to more traditional imaging methods.

What are some examples? RSNA attendees will find presentations that address the use of emergency ultrasound to diagnose acute appendicitis; high-resolution, contrast-enhanced ultrasound for gastrointestinal applications and to distinguish between thyroid adenomas and carcinomas; and fused ultrasound/MR guidance for prostate interventions or to target biopsies.

Of course, expect much discussion of breast ultrasound, with researchers giving attendees an update on the "Connecticut experiment" -- the original breast density notification law that launched a movement. Presenters will discuss whether it's possible to minimize unnecessary follow-up in women who have BI-RADS 3 lesions at screening ultrasound, and explain whether using breast ultrasound for further assessment after negative mammography spot views appears to do more harm than good.

And if meeting participants are looking for a knowledge boost, there's no need to worry: Along with the scientific sessions, RSNA 2014 is hosting plenty of refresher courses, covering topics from elastography imaging and musculoskeletal ultrasound to ultrasound-guided interventional breast procedures and ultrasound/photoacoustic molecular imaging.

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

Scientific and Educational Presentations
Conn. 'experiment': Ultrasound keeps finding cancers in dense tissue
Sunday, November 30 | 11:05 a.m.-11:15 a.m. | SSA01-03 | Arie Crown Theater
Four years after breast density notification legislation was enacted in Connecticut, the addition of screening breast ultrasound for women with dense tissue has continued to improve breast cancer detection compared with mammography alone, according to research to be presented on Sunday.  
Photoacoustic US works as well as MR thermal imaging for head/neck cancer
Sunday, November 30 | 11:45 a.m.-11:55 a.m. | SSA21-07 | Room S405AB
Photoacoustic ultrasound thermography is a promising new technique for guiding and monitoring photothermal ablations for head and neck cancers, according to researchers from the University of Texas.  
O-mode ultrasound reduces artifacts
Sunday, November 30 | 12:05 p.m.-12:15 p.m. | SSA21-09 | Room S405AB
In this Sunday presentation, researchers will discuss how O-mode ultrasound is a promising new technique that reduces artifacts typical with B-mode imaging.  
Dynamic contrast-enhanced ultrasound can be standardized
Sunday, November 30 | 12:30 p.m.-1:00 p.m. | PHS130 | Lakeside Learning Center
Dynamic contrast-enhanced ultrasound can be standardized, which could open the door to more multicenter studies, French researchers have concluded.  
Is it possible to avoid unnecessary follow-up after screening ultrasound?
Sunday, November 30 | 1:00 p.m.-1:30 p.m. | BRS244 | Lakeside Learning Center
Is it possible to minimize unnecessary follow-up in women who have BI-RADS 3 lesions at screening ultrasound? Yes, according to research that will be presented in this Sunday poster session.  
Ultrasound matches MR for assessing post-op flexor tendon
Sunday, November 30 | 1:00 p.m.-1:30 p.m. | MKS346 | Lakeside Learning Center
Ultrasound and MR are complementary modalities for distinguishing complications -- either rupture or adhesions -- after repair of the digital flexor tendon, according to French researchers.  
Musculoskeletal ultrasound offers cost-effective alternative to MR
Sunday, November 30 | 1:00 p.m.-1:30 p.m. | MKS348 | Lakeside Learning Center
Musculoskeletal ultrasound of the foot and ankle can play an important role in clinical decision-making -- offering a cost-effective and readily available alternative to MR, concluded researchers from the Cleveland Clinic.  
US works as well as MR, MRA for evaluating rotator cuff tears
Tuesday, December 2 | 9:05 a.m.-9:15 a.m. | VSMK31-03 | Room E450A
Ultrasound, MR, and MR arthrography (MRA) are all accurate ways to assess recurrent rotator cuff tears, according to clinical findings to be presented by University of Michigan researchers.  
Ultrasound tops x-ray for diagnosing, staging rheumatoid arthritis
Tuesday, December 2 | 11:00 a.m.-11:10 a.m. | VSMK31-10 | Room E450A
Ultrasound is a reliable technique for diagnosing and staging rheumatoid arthritis, and it can detect more erosions than x-ray, researchers from Tunisia have found.  
Ultrasound comparable to CT for bone lesion sampling
Tuesday, December 2 | 10:00 a.m.-10:10 a.m. | VSMK31-07 | Room E450A
Ultrasound and CT show comparable diagnostic accuracy for sampling bone lesions, according to research to be presented during this Tuesday morning session.  
Supersonic shear imaging helps assess Achilles tendon changes
Tuesday, December 2 | 11:10 a.m.-11:20 a.m. | VSMK31-11 | Room E450A
Supersonic shear imaging has the potential to characterize changes in the Achilles tendon brought on by aging and disease, and it could perhaps decrease the risk of injury, according to this presentation to be given on Tuesday.  
Breast US after negative mammo spot views causes more harm than good
Wednesday, December 3 | 3:20 p.m.-3:30 p.m. | SSM01-03 | Arie Crown Theater
In this presentation, Canadian researchers will discuss how using breast ultrasound for further assessment after negative mammography spot views can cause more harm than good.  
MR-guided transurethral US ablation viable for treating prostate cancer
Thursday, December 4 | 10:40 a.m.-10:50 a.m. | SSQ10-02 | Room E450B
MR-guided transurethral ultrasound ablation is a feasible, minimally invasive, and safe way to treat organ-confined prostate cancer, according to research to be presented on Thursday.
