Spectral Doppler waveform assessment is a crucial diagnostic tool employed in identifying peripheral arterial  diseases. The prevalence of conflicting and overlapping Doppler waveform terminologies has been a long-standing concern. To address this issue, the Society for Vascular Medicine (SVM) and the Society for Vascular Ultrasound (SVU) initiated a writing committee comprising experienced sonographers and physicians. Their collective expertise in ultrasound performance, interpretation, research, and teaching led to the development of an expert consensus document aimed at proposing a universal nomenclature for describing arterial Doppler waveforms. This document strives to enhance communication among practitioners caring for vascular patients, offering a standardized framework to accurately convey the presence and severity of peripheral arterial diseases.
