Ultrasound's utility will be on full display at this year's RSNA annual meeting, showing its merit in a wide variety of clinical applications.
Research to be presented at the annual meeting in Chicago will explore the modality's clinical applications in musculoskeletal, pediatric, abdominal, and women's imaging among other areas. This includes advancements in ultrasound in recent years, such as the use of contrast for improved imaging, elastography and color Doppler for assessing complex pathologies, and using imaging data in AI models.
Studies will also evaluate ways to further improve the modality's capabilities by reassessing the physics side of ultrasound, such as attenuation and echogenicity, as well as the use of interferometry. Ultrasound's performance will also be compared with CT and MRI in detecting pathologies, as well as for how ultrasonic measures validate treatment strategies such as radiotherapy in cancer treatment and surgery for musculoskeletal pathologies.
Furthermore, ultrasound's use as a supplemental tool will be explored, including for breast cancer detection and follow-up imaging for assessing aneurysm risk. Additionally, research will show how using sonographic imaging data in machine learning can improve upon current risk assessment models, such as TI-RADS for thyroid nodule assessment and avoiding unnecessary biopsies.
Contrast-enhanced ultrasound (CEUS) will also take center stage in the Windy City; researchers will demonstrate the promise of CEUS for assessing ablation treatment and evaluating cancers undergoing chemotherapy. Other presentations will compare the efficacy of multiple contrast agents in ultrasound and fusion imaging.
AI studies to be showcased will also highlight how using ultrasound features and parameters can lead to better diagnosis and assessment of suspicious findings. This includes using conventional ultrasound and elastography data to better inform radiologists for head and neck imaging of both adult and pediatric patients.
All in all, ultrasound is a versatile modality that can help detect and diagnose pathologies such as liver cancer, breast cancer, and thyroid cancer, with RSNA presentations aiming to showcase these benefits that are possible, of course, without the ionizing radiation of some other imaging modalities.
RSNA 2023 attendees can also attend various education sessions exploring the latest innovations and techniques in sonography. These include case reports, updates in neonatal imaging, pediatric oncology and emergency medicine, advanced ultrasound technology and applications, AI in ultrasound imaging, contrast agent use, and more.
