Chapter 1: Orientation and Labeling in Obstetric and Gynecologic Imaging Flashcards
position of the fetus in utero
fetal lie
left lateral decubitus position with the knees and thighs toward the chest
Sims position
toward the head or cranium
cranial
body in the erect position with the palms forward and feet pointed forward
anatomic position
form, structure, and location of organs
morphology
toward the back or spine
dorsal
term used to describe which portion of the fetus will deliver first
fetal presentation
toward the belly or front
ventral
toward the feet or tail end
caudal
The sagittal scan plane refers to a(n):
vertical plane dividing the fetal or female body into right or left sections
The _____ view divides the patient body into anterior and posterior planes
coronal
A transabdominal transducer provides a position indicater (i.e, notch, groove) comparable to an image marker such as an arrow or dot. The position indicator shoudl be toward the _____ for longitudinal imaging and toward the patient’s _____ in transverse imaging.
head, right
A fetus positioned with the cranium in the superior uterus, rump in the inferior uterus, and spine at the maternal right uterus is labeled:
breech, left lateral
Choose the position that is the same as a cephalic presentation:
a. Frank breech
b. oblique
c. transverse
d. vertex
d
Minimal documentation on a technical impression worksheet should include:
examination date, patient name and identifiers, specific examination requested
Select the appropriate statement for a sonographer’s technical impression.
a. Ruptured ectopic pregnancy
b. retroflexed uterus
c. posterior cul-de-sac free fluid
d. heterogeneous right ovary with a 2 x 4 mm echogenic shadowing focus
d
Ipsilateral means:
located or affecting the same side of the body
The aorta, IVC, and iliac vessels lie ____ to the female reproductve organs
deep
Select the incorrect gynecologic abbreviation:
a. AF anteflexed
b. FHR fundal height requirement
c. OV ovary
d. CX cervix
b
An endovaginal sagittal anteflexed or anteverted uterus image requires the transducer orientation marker to be placed at ____ o’clock.
12
The LPO position needs a patient to lie on the ____ posterior surface with a _____ anterior surface.
left, right
In obstetrics, RPOC means:
retains products of conception
The _____ portion of the fallopian tubes attaches onto the lateral uterus
proximal
The term _____ indicates that the fetal buttocks are toward the cervix
breech
The term ____ indicates that the fetal cranium is positioned toward the cervix
vertex
If the uterus does not lie in a true longitudinal or transverse position, it can be identified by ____, ______, or _____ the transducer to align it into an identifiable plane
rocking
sliding
angling
The abdominal wall is _____ to the uterus
superficial
TAH means:
total abdominal hysterectomy
To direct fetal weight from the maternal great vessels use the ____, _____, and _____ position.
RLD
LLD
Sims
LGA means:
large for gestational age
To identify cranial anatomy in late pregnancy when the transabdominal approach is not adequate, use either a _____ or _____ approach.
translabial
endovaginal
Common interchangeable terms to describe the long axis of the uterus
sagittal, parasagittal, longitudinal
Explain the correct direction to rotate the TA or EV transducer to obtain a transverse image
rotate transducer counterclockwise to place marker to patient’s right
3 common anatomic scanning plans
coronal
sagittal
transverse
patient positions used for transabdominal approach
decubitus positions, sims position, supine or dorsal, lithotomy/modified lithotomy, left-right posterior oblique, reverse Trendelenburg
The apex of a transvaginal/ endovaginal image corresponds to what part of the anatomy?
anatomy closest to the face of the transducer
toward the head, anatomy or pathology closer to the head, the upper portion or locations of the body, organ, or pathology
superior (cranial, cephalic)
toward the feet, anatomy or pathology closer to the feet, the lower portion or location of the body, organ, or pathology, posterior or back of head (brain)
inferior (caudal)
