ACEP ID:

Definition of Clinical Ultrasonography

Reaffirmed June 2022

Originally approved January 2014



The American College of Emergency Physicians (ACEP) defines clinical ultrasonography as a diagnostic modality that provides clinically significant data not obtainable by inspection, palpation, auscultation, or other components of the physical examination. It is a distinct clinical modality, not an adjunct to or extension of the physical examination.
