GE’s Vscan Portable Ultrasound Proven Effective in New Study

July 6th, 2011 Smit Shah News


We’ve been following GE Healthcare’s Vscan portable ultrasound for nearly two years, and now Scripps Health has announced results of the first peer reviewed study of the device. The ultrasound system, which weighs just one pound and has roughly the footprint of a smartphone, has been marketed as a modern replacement for stethoscopes, so researchers tested its ability to diagnose structural heart conditions. The results of the study were published in yesterday’s issue of Annals of Internal Medicine:

In the study, pocket ultrasound images were adequate for visualizing ejection fraction 95 percent of the time, wall motion abnormality 83 percent of the time, left ventricular end-diastolic dimension 95 percent of the time, pericardial effusion 94 percent of the time, mitral valve 90 percent of the time, aortic valve 82 percent of the time, and inferior vena cava (the large vein carrying blood to the heart) size 75 percent of the time. Accuracy of interpretation of pocket ultrasound images was highest when assessing ejection fraction and aortic valve, and lowest when assessing inferior vena cava size. Accuracy and between-physician agreement was higher for experienced cardiologists than for less experienced cardiology fellows.

Press release: Scripps Study First to Validate Usefulness of Pocket Ultrasound Device; Could Significantly Reduce Cost and Inconvenience of Traditional Echocardiograms…
