Overview of Diagnostic Ultrasound Safety

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Ultrasound is widely regarded as a safe imaging modality; however, emerging ultrasound‐based techniques—such as shear wave elastography and contrast‐enhanced ultrasound—operate with varying acoustic output parameters that may approach or exceed traditional diagnostic limits. As these technologies are increasingly integrated into human research studies,
