SONO 117-Biometry quiz (Answered)
100% Correct.
In order to be able to measure the BPD and HC what plane should be visable
BPD and HC
What should be visualized in the BPD and HC
thalami, midline falx, and the boxlike cavum septi pellucidi or CSP
the presence or absence of the CSP is a key factor in defining
abnormal brain activity
The BPD can be measured through any plane that crosses the
3rd ventricle, thalami, and CSP
know this image
The calvaria should be
smooth and symmetrical as indicated
The cursor in the near field should be placed on the _________ of the calvaria and the cursor in the far
field should be placed on the ___________
outer edge
inner edge
measurement of the HC is done through the plane that crosses the
third ventricle, thalami, and CSP
with the HC, the CSP should be
visible in the anterior portion of the brain
in HC, the caliper placement around the calvarial wall should not include
scalp thickness or skin
how does the CSP appear
, as a box like structure in the anterior portion of the brain as demonstrated. The hyperechoic lines
represent the medial walls of the lateral ventricle
image of CSP
what represents the columns of fornix
a three line structure, paired nerve columns, located just inferior of the CSP
this abnormality is defined when the AP diameter is longer than the transverse diameter is less than 70%
Dolicocephaly
Dolicocephaly is seen in a number of conditions such as
oligohydrmnios and multiple gestations
This abnormality is described as transverse diameter is greater than AP diameter and the CI is less than
86%
Brachcephaly
Brachcephaly is seen in
conditions like synostosis, trisomy 21, and Hydrocephalus
where should the AC measurement be taken
at the skin line on a trv view of the level of the umbilical vein, portal sinus, and fetal stomach.
what should we make sure is symmetrical in a AC measurement
ribs
The long axis of the diaphysis of the femur is most accurately measured when the ultrasound beam of
insonation is
is perpendicular to the shaft
what should not be included in the femoral meausrement
the cartilage at the end of the femur
The principles of the HL measurement or humerus length corresponds to those of the
femur
HL, the insonation of the us beam is best directed
