WebDoppler Spectrum of Normal Lower Extremity Arteries. Typical measurements obtained in a Spectral Doppler analysis peak systolic velocity (PSV), minimum diastolic velocity … Web2 de dez. de 2024 · Explanation. When traveling with their greatest velocity in a vessel (i.e. during systole), red blood cells exhibit their greatest magnitude of Doppler shift. The spectral Doppler system utilizes Fourier analysis and the Doppler equation to convert this …
Duplex Criteria for Grading of External Carotid Stenosis
WebReceiver-operator curve analysis was used to determine optimal criteria in identifying ECA stenosis of >50%. Results: In patients with little ipsilateral ICA disease, for the detection of ECA stenosis of ≥50%, an ECA PSV >148 cm/sec provided a sensitivity of 80%, specificity of 76.2%, and an overall accuracy of 77.1%. Web1 de mai. de 2003 · Concomitant significant superior femoral artery and bilateral iliac disease did not influence these findings. Conclusion: CFA PSV 45 cm/s or less combined with a monophasic waveform is highly predictive of ipsilateral iliac occlusion. These results were independent of contralateral iliac and distal superior femoral artery disease. data recovery tools linux
