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
Measurement used to compare the resistance of a medium to the propagation of flow
Impedance indices
Main vessel carrying oxygenated blood toward the uterus
Uterine artery
Difference between peak systole and end diastole
S/D ratio
Anatomical parts added, attached, or adjunct to another or others
Adnexa
Days 15-28 of the menstrual cycle
Secretory phase
Small vascular structures found along the periphery of the uterus
Arcuate vessels
Days 10-14 of the menstrual cycle
Proliferative phase late
Normal arterial flow is seen as
Alternating quick uptake systolic peak followed by a lower diastolic flow
Blood velocity traveling highest in the midvessel
Laminar flow
Name the vessel (appearing as a tubular structure) often seen sonographically in the uterine myometrium
Arcuate artery
The functional layer of the endometrium is supplied by the
Radial and spiral artery
What allergy should a sonographer question about every patient
Latex
The presence of blood flow in a select area or vessel at a known depth with a sample volume describes
Pulsed Doppler
