June 2022: The Speed of Sound: Hip Fracture Nerve Blocks Are Simple with Ultrasound
Hip fracture pain management can be challenging, often requiring large doses of narcotics, which can be a problem in older patients. If you’ve been reluctant to try nerve blocks for hip fractures, ultrasound can help. Watch this video of the target area, where the femoral artery and vein are seen initially, but moving the transducer laterally reveals the femoral nerve and iliacus muscle.

Artificial intelligence can boost breast cancer diagnoses.
Ultrasound breast exams, while an important tool, have caused numerous false breast cancer diagnoses. A team of NSF-funded researchers have developed an AI computer program trained to see distinctive patterns in thousands of ultrasound breast images, helping physicians to diagnose breast cancer ...This is an NSF Multimedia Gallery item.

November 2021: The Speed of Sound: How to Assess Volume Status with VExUS
Dr. Butts explains how a handful of ultrasound measurements can estimate the degree of venous congestion at the organ level. This video shows how the hepatic veins can sometimes be found from the position used to examine the IVC. If they are not seen in this view, they can also often be found from a right flank approach.

July 2021, Video 2: The Speed of Sound: Diagnosing COVID-19 with Ultrasound
This video shows a patient with interstitial syndrome and COVID-19 pneumonia. Note the presence of B-lines that seem to appear and disappear, consistent with patchy areas of involvement. Also note the irregular pleural line, caused by subpleural consolidations. Read more in Dr. Butts’ column at http://bit.ly/SpeedSound. (Source: Emergency Medicine News - Video)

Challenges and Innovations in Neonatal and Infant Imaging: A Look Across Modalities
This meeting brings together investigators who use fNIRS, EEG, MRI (structural, functional, and resting-state MRI, and DTI), MEG, and ultrasound imaging methods to study the neonatal and infant brain. Talks and discussions will compare and contrast these modalities based on considerations, trade-offs, and best practices related to image acquisition, study design, and data analyses. This meeting will include perspectives from a diverse group of investigators across multiple areas of expertise who will provide insight into the successes and challenges in studying the developing brain.For more information go tohttps://www.eve...
