Thermal effects of fetal US remain uncertain
A study on thermal effects of diagnostic fetal ultrasound could not confirm a causal relationship between exposure and obvious adverse effects. Study authors cautioned, however, that subtle effects cannot be ruled out and called for more research.

The report, led by Dr. Jacques S. Abramowicz of Rush University Medical Center, cited lab animal studies showing that pulsed ultrasound can produce in vivo temperature elevations and damage in tissues, particularly bone. Human studies have not shown the same results, however.
The research was published in April in the Journal of Ultrasound in Medicine as part of the American Institute of Ultrasound in Medicine's consensus report on the potential bioeffects of diagnostic ultrasound.
What New Research Reveals About Novice Use of AI-Guided Cardiac Ultrasound
April 4th 2025In a study recently presented at the American College of Cardiology (ACC) conference, researchers found that novice use of AI-guided cardiac ultrasound after an AI-enabled electrocardiogram increased the positive predictive value for reduced left ventricular ejection fraction (LVEF) or aortic valve stenosis by 33 percent.
New AI-Enabled Portable Ultrasound May Facilitate 50 Percent Reduction in Cardiac Imaging Scan Time
March 28th 2025Artificial intelligence (AI)-powered measurement capabilities provide key features with the Compact Ultrasound 5500CV device, which was unveiled at the American College of Cardiology (ACC) conference.
