May 12, 2025 · The outline (envelope) of the normal multiphasic peripheral artery spectral waveform is a rapid systolic upstroke (time to peak) and sharp systolic downstroke which crosses the baseline (see …

Aug 6, 2025 · Diastolic flow reversal is generally considered normal but pandiastolic forward flow is abnormal in the peripheral arteries 2. These categorizations differ for the cerebrovascular and …

Normal flow waveforms in the cerebral arteries show a rapid systolic upstroke, reflecting normal proximal vessels and cardiac function, but the characteristics of the diastolic portion of the wave-form are …

Serial temperatures measured until finger returns to pre-test temperature, with recovery time of 10 minutes or less being normal. Rarely used and not specific to disease, with 50% false positive rate.

Feb 26, 2021 · A normal color flow duplex ultrasound and triphasic waveforms at the common femoral artery (CFA) indicate normal aortoiliac flow since the aorta and iliac arteries are proximal to the CFA.

The common femoral artery (CFA) is lateral to the femoral vein (FV) on a transverse scan at the inguinal crease. Note that the size of the color box is as small as possible.

Normal laminar flow: In the peripheral arteries of the limbs, flow will be triphasic with a ‘clear spectral window’ consistant with no turbulence. The spectral window is the area under the trace.

Dec 30, 2019 · (A) Color flow image and pulsed Doppler waveforms taken from the left common femoral artery ( CFA ) demonstrate a triphasic flow pattern with peak systolic velocity in the normal range …

A monophasic waveform is characterized by a single, downward deflection during systole, often with minimal or absent diastolic flow. This pattern signifies a significant reduction in vessel compliance …

Normal in early postoperative period (up to 3 - 6 weeks) = Low resistance pattern (forward diastolic flow) Normal after 3 - 6 weeks = High resistance pattern (triphasic waveform)
