What is the arrow pointing at?
Temporal Tap, which can be used to differentiate between ICA and ECA
What is the color flow representing here?
Normal Flow separation in carotid bulb. If there is plaque build up then flow separation disappears.
Where are these Waveforms A & B taken from?
A. Prox ICA bulb
B. Prox ICA bulb (flow separation)
What pathology am i? i am smooth and uniform in appearance and with hypoechoic.
Homogenous Plaque
What pathology am I? I can be described as mixed echogenecity plaque and have areas of calcium that may cause brighter echoes and acoustic shadowing. I also have irregular surface.
Heterogenous Plaque
What does the Image show?
Dissection/ False Lumen
What waveform is shown in the image?
Pseudoanuerysmal to and fro waveform is shown
What waveform is shown in the image?
Pseudoaneurysmal to and fro waveform. notice the YIN YANG sign
Where are these waveforms taken from?
A. CCA B. ECA C. ICA
What waveform is shown in the image?
Tardus Parvus Waveform. The waveform contour distal to significant stenosis will be dampened, with decreased velocities, delayed accel and rounded peak.
What waveform is shown in the image?
Proximal to stenosis. waveform has high resistance pattern with low velocity or absent diastolic flow.
What waveform is shown in the image?
Hesitant Doppler Wavefform contour. Result of a steal. may look like a bunny rabbit in Subclavian Steal.
What kind of color flow is shown in the above image
String Sign. it has a blunted, low velocity . to be found in severly diseased ICA in which small string like lumen remains.
What is the color doppler suggesting in the image.
Choke Lesion. A severe distal CCA obstruction with continued patency of the Carotid bifurcation. flow typically reverse in the ICA to supply ECA.
What waveform is shown in the image?
Its a THUMP ARTIFACT. (-_-)
What is shown in the image?
Tortuous and Kinked vessel. t's are asymptomatic whereas kinks may cause stroke or TIA.
