Neck Doppler ultasound

🩺

Neck — Doppler

Patient prep & head positioning Doppler settings: PRF, wall filter, gain, angle Sample volume placement & spectral optimization

CCA / ICA / ECA anatomy & bifurcation Vertebral & subclavian arteries

PSV / EDV / RI / PI — acquisition & interpretation Aliasing, reverberation & artifact recognition

ICA stenosis: PSV thresholds, ratio methods Occlusion vs near-occlusion vs pseudo-occlusion

Plaque echogenicity, surface, ulceration Post-stenotic turbulence & velocity patterns

Retrograde vertebral flow patterns Provocative maneuvers & interpretation

Diffuse increased flow (thyroiditis) vs focal hypervascularity Nodule central/peripheral flow patterns

IJV waveform, compressibility & thrombus detection Valsalva effect & valve assessment

Post-CEA: residual stenosis, restenosis surveillance Stent assessment & intra-stent velocities

PSV/EDV meas. technique, ratio calculations (ICA/CCA) Suggested wording, urgent flagging & follow-up guidance

Angle error, sample misplacement, pseudo-occlusion Avoiding overcall: aliasing vs true turbulence

Minimum spectral & color images per vessel Competency checks & standardization

Annotated Doppler cases & normal/abnormal waveforms Reference protocols & guideline links

Society guidelines (vascular/hypertension/ENT) Key review articles & references
