Cerebrovascular testing: Carotid intima media thickness

Terms in this set (23)

CIMT testing is used to predict patients with
cardiovascular disease
which of the following carotid scan windows should be used to record loops or still frames in CIMT testing
anterior
a limitation to CIMT testing would be
-suboptimal visualization by b-mode including but not limited to lack of visible double line along the far arterial wall, motion artifact from the jugular vein or deep vessels
-tortuous
-intraobserver variability of CIMT measurements range between 3.7-7.8%
the sonographer should look for the characteristic ___ lumen-intima and media-adventitial interfaces on B-mode image
double line
a 60-yr old woman is at increased risk for cardiovascular disease when she has
< 2 CVD risk factors
repeat CIMT measurements should be within ___ of each other
0.05mm
CIMT testing is more accurate when the far-wall of the artery is used since the US beam travels across
a more echogenic to less echogenic surface
how far should the cursor be from the flow divider when recording a representative distal common carotid artery image
1 cm
how does CIMT increase between the ages of 20-90 yrs
3 fold
what part of the cardiac cycle should be used to capture images of the arterial walls
when systolic-diastolic differences are at minimum during end-diastole
CIMT testing uses gray scale images to identify areas of increased ___ along the lumen-intima & media-adventitia interfaces
thickness
the typical depth for scanning the carotid artery during CIMT testing is
4 cm
report the presence of ___ along the arterial walls, which may result in technically suboptimal images
plaque/calcific arterial shadowing
identify a ___ segment of the distal CCA to begin CIMT analysis is ___ cycle(s)
straight
there is a link between CIMT & severe cases of __ disease, stroke & peripheral vascular disease
coronary heart disease
