Term Description

Time-average of the maximum Doppler shift frequency envelope over the cardiac cycle.
Source: Regenstrief LOINC

Part Description

LP6617-7   US.doppler
Doppler ultrasound detects the shift in frequency of ultrasound signals reflected from moving objects. Conventional Doppler techniques assess the velocity of blood flow by measuring high-frequency, low-amplitude signals from small, fast-moving blood cells.
