NIH Director's Seminar Series: Novel measures of fetal growth and development: state of the art tools to assess fetal health
Healthy fetal growth is essential for newborn well-being, pediatric development, and subsequent adult health consistent with the developmental origins of health and disease hypothesis. Both fetal undergrowth and overgrowth portend adverse outcomes and require clinical intervention. Fetal growth is often assessed by ultrasonographic measurement of two-dimensional (2D) fetal biometrics to calculate an estimated fetal weight (EFW) that is then compared against a standard. However, EFW is a poor measure of actual growth. Recently, more sophisticated measures have been developed including three-dimensional (3D) ultrasound that ...

Neuroscience Seminar: Targeting the Ventral Pallidum to Modulate Compulsive Behavior
Research in Dr. Creed's lab focuses on how chronic pain, stress and addictive drugs induces changes in neural circuits that underlie symptoms of psychiatric disorders. The lab uses a range of techniques including in vivo and patch clamp electrophysiology, genetic sequencing, neuroanatomy, optogenetics and behavior to study changes in function in the ventral basal ganglia in models of addiction, mood and chronic pain disorders. The main goal of the lab is to leverage insight from circuit studies to develop novel neuromodulation therapies for these disorders, including deep brain stimulation (DBS) and targeted drug delivery ...

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)
