Fig. 14From: Contrast-enhanced ultrasound performed under urgent conditions. Indications, review of the technique, clinical examples and limitationsA 55-year-old woman. No flow is seen in the left internal carotid artery (LICA) on colour Doppler US (a), obviously due to a mixed echogenicity plaque (arrow) at its origin. The left common (LCCA) and external (LECA) carotid arteries and branch are patent. Occlusion of the LICA is confirmed post contrast injection (b). LCCA, LECA and branch enhance normally, while no contrast is present in the LICA. In this case CEUS confirmed colour Doppler findings, increasing confidence of the performing radiologist at 3:00 in the morning, without the need for an urgent angiographyBack to article page
