Chapter 6 Doppler Eval of the Pelvis Flashcards
What term defines the physiologic process of growing new vessels
Angiogenesis
This doppler measurement takes the highest systolic peak minus the highest diastolic peak divided by the highest systolic peak
Pourcelot resistive index
What days does the early proliferative phase occur
5-9
Which vessel carries blood toward the uterus
Uterine artery
Where should the sonographer obtain the uterine artery doppler
Laterally to the cervical level
Identify the normal uterine arterial proliferative phase spectral doppler flow velocity
0.88 + 0.05
What is the definition of a low-resistance arterial flow
High systole, high diastole
What is the optimal angle of incidence to obtain a spectral tracing
60 degrees
Where does the uterine artery anastomoses with the ovarian artery
At the uterine cornua
What is the normal flow velocity in the nongravid uterine artery
5-10 cm/sec
What describes spectral doppler flow found surroudning the corpus luteal cyst
Low resistance flow
What is a vascular plexus of arteries and veins without an intervening capillary network
AVM
Doppler measurement that uses peak systole minus peak diastole divided by the mean
Pulsatility index
Blood vessels that supply oxygenated blood to and drain deoxygenated blood away from the ovaries
Ovarian vessels
Abnormal connection between veins and arteries
Arteriovenous malformation
