RSNA 2019 Ultrasound Preview

Road to RSNA 2019: Ultrasound Preview

By Kate Madden Yee, staff writer
November 11, 2019

What's not to like about ultrasound? It's cost-effective, portable, and noninvasive -- and it's proving to be an effective tool for a wide range of applications, from treating uterine fibroids and identifying hydrocephalus in children to diagnosing enlarged veins in patients with cirrhosis.

At this year's RSNA meeting, ultrasound's versatility will be on display via scientific presentations and posters, as well as refresher courses that will keep sonographers at the top of their game.

One hot topic at this year's meeting will be shear-wave elastography (SWE), a technique that allows for real-time quantification of tissue stiffness and, therefore, can be helpful in identifying cancerous lesions, which tend to be stiffer than surrounding tissue. RSNA 2019 attendees will also encounter vigorous discussion regarding the uses and benefits of contrast-enhanced ultrasound (CEUS), ultrasound molecular imaging, and using the modality for musculoskeletal applications -- ranging from imaging the Achilles tendon and the knee to the shoulder and the elbow.

On the women's imaging side, look for presentations that explore how ultrasound can help monitor breast cancer treatment response, differentiate benign from malignant lesions, and even reduce the need for sentinel node biopsy in women with early-stage disease -- as well as discussion about the pros and cons of automated breast ultrasound (ABUS) compared with handheld and the use of ABUS as a supplemental modality in women with dense breast tissue.

Check out education exhibits that will touch on ultrasound's role in predicting the molecular subtype of breast cancer and diagnosing incompetence in veins, as well as a controversy session that will explore which modality is best for screening and surveillance of hepatocellular carcinoma (is it ultrasound, CT, or MR?).

Finally, RSNA 2019 will be offering a variety of ultrasound refresher courses that will cover dynamic musculoskeletal imaging, thyroid sonography, ultrasound-guided interventional breast procedures, breast elastography, CEUS, liver elastography, and abdominal Doppler.

Keep reading for highlights of just some of the ultrasound research and posters scheduled for presentation at this year's meeting. View the complete list of abstracts for the 2019 scientific and educational program on the RSNA website.

Scientific and Educational Presentations
CADx for breast ultrasound comparable to radiologists
Monday, December 2 | 12:45 p.m.-1:15 p.m. | BR254-SD-MOB4 | Lakeside, BR Community, Station 4
Computer-assisted diagnosis (CADx) for breast ultrasound performs comparably to expert radiologists, according to study findings to be presented in this poster session on Monday afternoon.
Breast ultrasound useful for average-risk women
Monday, December 2 | 3:10 p.m.-3:20 p.m. | SSE02-02 | Room E451B
In this scientific session, researchers will discuss how screening breast ultrasound is a useful supplement to mammography in women at average risk of breast cancer, not just those at high risk.
Use ultrasound to monitor myofascial pain syndrome
Monday, December 2 | 3:10 p.m.-3:20 p.m. | SSE22-02 | Room E352
A novel B-flow ultrasound method and shear-wave elastography offer a way to monitor the treatment of myofascial pain syndrome with botulinum toxin, according to Swiss researchers.
Is supplemental whole-breast US needed after DBT?
Monday, December 2 | 3:20 p.m.-3:30 p.m. | SSE02-03 | Room E451B
Do women with dense breast tissue who have a normal digital breast tomosynthesis (DBT) exam need supplemental whole-breast ultrasound imaging? Perhaps not, according to research to be presented Monday afternoon.
Novel phantoms help evaluate ultrasound systems
Monday, December 2 | 3:30 p.m.-3:40 p.m. | SSE22-04 | Room E352
In this presentation, researchers will describe how breast phantoms can help in the evaluation of ultrasound systems and different image optimization controls.
Photoacoustic US shows promise for visualizing lymphatic vessels
Monday, December 2 | 3:40 p.m.-3:50 p.m. | SSE22-05 | Room E352
A new optical imaging technique based on photoacoustic technology and ultrasound shows promise for visualizing small blood vessels and lymphatic vessels in the extremities of patients with lymphedema, according to researchers from Japan.
Breast ultrasound helpful supplement even after DBT
Monday, December 2 | 3:50 p.m.-4:00 p.m. | SSE02-06 | Room E451B
In this session, University of Pittsburgh researchers will discuss how whole-breast ultrasound performed by a technologist can find more cancers in women with dense breast tissue even after screening digital breast tomosynthesis (DBT) -- although it does increase the recall rate.
Trust whole-breast US for supplemental breast cancer screening
Wednesday, December 4 | 11:50 a.m.-12:00 p.m. | SSK02-09 | Room E450A
Whole-breast ultrasound performed by a technologist is an effective way to provide adjuvant screening to women with dense breast tissue, according to research to be presented on Wednesday morning.
Ultrasound tomography helps characterize breast cancer
Wednesday, December 4 | 12:45 p.m.-1:15 p.m. | BR278-SD-WEB5 | Lakeside, BR Community, Station 5
In this poster presentation, researchers will discuss how ultrasound tomography is a feasible and accurate tool for characterizing stiffness of breast lesions.
SWE identifies hydrocephalus in infants
Thursday, December 5 | 10:40 a.m.-10:50 a.m. | SSQ17-02 | S105AB
Shear-wave elastography (SWE) is viable in infants with hydrocephalus and could offer a way to provide additional diagnostic imaging and monitoring of children with this condition, according to researchers from Germany.
Testicular volume helps diagnose torsion
Thursday, December 5 | 11:10 a.m.-11:20 a.m. | SSQ17-05 | S105AB
In this session, researchers will describe how using ultrasound to evaluate pediatric testicular volume can help diagnose torsion.
Spleen elastography detects esophageal varices
Friday, December 6 | 11:30 a.m.-11:40 a.m. | SST03-07 | E352
Spleen elastography is an effective, less invasive way to detect and assess esophageal varices in patients with cirrhosis, enabling these patients to start immediate treatment with beta-blockers, according to research to be presented Friday morning.
