F
Normal Femoral Artery Peak Systolic Velocity on Ultrasound
Normal femoral artery peak systolic velocity ranges 89–141 cm/s (common) and 77–108 cm/s (superficial) on duplex ultrasound.
I
Normal Internal Carotid Artery Stenosis Grading on Ultrasound
Learn the Society of Radiologists in Ultrasound consensus criteria for grading internal carotid artery stenosis by Doppler ultrasound, including PSV, EDV, and ICA/CCA ratios.
L
Normal Left Gastric Vein Diameter: Ultrasound Reference
Normal left gastric vein diameter is less than 6 mm on color Doppler ultrasound; enlargement is a key marker of portal hypertension and variceal risk.
P
Normal Popliteal Artery Peak Systolic Velocity on Ultrasound
Normal popliteal artery peak systolic velocity on duplex ultrasound ranges from 55–82 cm/s, a key benchmark for diagnosing peripheral arterial disease.
Normal Portal Vein Velocity on Ultrasound
Normal portal vein velocity on Doppler ultrasound ranges from 20–30 cm/s, a key metric for detecting portal hypertension and hepatic vascular disease.
R
Normal Renal Artery Velocity Size on Ultrasound
Normal peak systolic renal artery velocity on Doppler ultrasound is less than 200 cm/s, a key threshold for detecting renal artery stenosis.
Normal Renal Resistive Index Size on Ultrasound
Learn the normal renal resistive index on Doppler ultrasound, its clinical thresholds, and how values above 0.7 suggest obstruction or intrinsic disease.
T
Normal Testicular Resistance Index Size on Ultrasound
Normal testicular arterial resistance index (RI) on Doppler ultrasound ranges from 0.48 to 0.75, aiding diagnosis of torsion and ischemia.
