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)

July 2021, Video 1: The Speed of Sound: Diagnosing COVID-19 with Ultrasound
This video shows a normal air-filled lung. Contrast it with video 2, which shows interstitial syndrome and COVID-19 pneumonia. Note in this one how the A-lines are visible as the lung slides back and forth. 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...

June 2021, Video 3: The Speed of Sound: Pneumothorax: Ultrasound Makes the Diagnosis
his video shows a lung point, the transition between normal lung sliding and pneumothorax. Christine Butts, MD, says note the sliding motion on the left of the image and the lack of sliding on the right. Read more in her column at http://bit.ly/SpeedSound. (Source: Emergency Medicine News - Video)

June 2021, Video 2: The Speed of Sound: Pneumothorax: Ultrasound Makes the Diagnosis
This video shows a lack of sliding, says Christine Butts, MD. Note also the absence of comet tails because the visceral pleura is not visible here. Read more in her column at http://bit.ly/SpeedSound. (Source: Emergency Medicine News - Video)

June 2021, Video 1: The Speed of Sound: Pneumothorax: Ultrasound Makes the Diagnosis
This video demonstrates the “slide sign” in which the visceral and parietal pleural layers slide past each other. Christine Butts, MD, says also note the comet tails, the short vertical lines emanating from the pleural layers that appear and disappear with movement.

November 2020: Speed of Sound: Confirming that Shoulder Relocation ‘Clunk’
Christine Butts, MD, says almost nothing is more satisfying than that “clunk” as the humeral head pops back into place and your follow-up x-ray shows that all is right with the world. Watch this video of a normal shoulder joint in motion with ultrasound where you can see the normal position of the humeral head within the glenoid and the motion when internally and externally rotating the arm.
