Often the sonologist comes across what looks like pretty large arterial plaques, both calcific and non calcific (soft plaques). It looks bad with possible severe stenosis, on B-mode ultrasonography. But switching on color Doppler ultrasound and spectral Doppler study change the picture. This is one such case.
Left CCA (common carotid artery) shows large calcific plaques, but there is less than 75% stenosis as seen from these images below:
This interesting intimal plaque appears to project into the lumen (arrowheads), possibly an ulcerated plaque with a kind of "flap".
The left ICA just above the carotid bulb:
The right side shows a moderate stenosis:
Spectral Doppler negates a severe stenotic disease:
