Sažetak
Background: Carotid plaque ulceration is associated with an increased risk of cerebral embolism. Still controversy of the diagnostic ability of conventional two-dimensional ultrasound and angiography to detect plaque ulcers exists. Three-dimensional ultrasound (3D US) facilitates visualisation of the luminal plaque surface. Methods: We tried to display 6 stenosed internal carotid arteries (ICA) with plaque ulcers by mean of B mode, color Doppler flow imaging (CDFI), power Doppler flow imaging (PDFI), 3D US and 3D PD. We performed 3D US examination of 6 ICA plaques with an ulcerated surface. B mode slices were obtained with l0 MHz linear array transducer. CDFI and PDFI were done in a standardised manner. 3D data sets were obtained with the same probe, free handed, in a defined period of time (10 seconds). The recorded images were reconstructed (TomTec imaging system) and volumetry was done. Results: Plaque ulcers were good visualised by B mode in 2/6 ICA, by CDFI mode in 416, by PDFI mode in 5I6 ICA and by 3D US and 3D PDFI in 6/6 ICA. The diameter of the plaque ulcers couldn't be measured by means of B mode. Mean diameter of plaque ulcers was in CDFI 2.7+/-44mm, in PDFI 3, 1+/-8mm, in 3D US 2, 55+/-21mm and in 3D PDI 2.74+/-29mm. Surface area of the ulcer wasn't measurable in B mode. Mean plaque ulcer surface was in CDFI 4.83+/-75mm2, in PDFI 5.6+/-3mm2, in 3D US 7.56+/-4mm2, and in 3D PDI 7.89+/-12mm2. Plaque volume couldn't be measured by mean of B mode. Mean plaque ulcer volume was in CDFI mode 12.9+/-3 mm3 ; &#8226 ; in PDFI mode 17+/-4.4 mm3, in 3D US l9+/-6mm3 and in 3D PDFI 21+/-4mm3.Conclusion: 3D US accompanied by PD enabled good visualisation and measurement of the plaque ulcers diameter, surface and volume.
