Ultrasound is the perfect modality for many clinical applications, due to its portability, noninvasive nature, lack of radiation, and relative cost-effectiveness. All these benefits translate into increased interest in putting the modality to use to diagnose and treat a variety of diseases, and this year's RSNA meeting will highlight new ways the technology is changing clinical practice.
One hot topic, in particular, will be contrast-enhanced ultrasound (CEUS), which researchers are finding can help diagnose liver cancer, preoperatively evaluate hyperparathyroidism, and monitor tumors following ablation. RSNA 2018 attendees will also encounter lively discussion regarding the uses and benefits of MR-guided focused ultrasound (MRgFUS), for everything from prostate cancer to uterine fibroids to using the technology in lieu of pain medication in patients with painful bone metastases.
There's no escaping the burgeoning interest in using artificial intelligence (AI) across all imaging modalities, and ultrasound is no exception. Researchers will present data from studies that explore the application of ultrasound AI that's applied for liver imaging and diagnosing thyroid nodules and gallbladder polyps.
In women's imaging, look for studies that investigate how ultrasound performs in breast screening -- especially relevant given the number of states passing dense breast tissue notification laws -- as well as how the modality works with digital breast tomosynthesis to stage disease. The presentations will also address ultrasound's accuracy for diagnosing ovarian torsion and the use of ultrasound tomography to measure breast tumor volume.
Finally, the RSNA will be offering a variety of ultrasound refresher courses that will cover key topics such as ultrasound for musculoskeletal applications and first-trimester pregnancy, as well as interventional procedures, emergency ultrasound pitfalls, and renal elastography.
