Beckground/Aim. Cerebrovascular diseases are the third leading cause of mortality in the world, following malignant and cardiovascular diseases. Therefore, their timely and precise diagnostics is of great importance. The aim of this study was to compare duplex scan Color Doppler ultrasonography (CDU) with multislice computed tomography angiography (MSCTA) in detection of morphological and functional disorders at extracranial level of carotid arteries. Methods. The study included 75 patients with 150 carotid arteries examined in the period from January 2008 to April 2009. The patients were firstly examined by CDU, then MSCTA, followed by the surgery of extracranial segment of carotid arteries. In 10 patients, the obtained material was referred for histopathological (HP) examination. We used both CDU and MSCT in the analysis of: plaque surface, plaque structure, degree of stenosis, and the presence of intraplaque hemorrhage. Results. The results obtained by CDU and MSCTA were first compared between themselves, and then to intraoperative findings. Retrospective analysis showed that MSCTA is more sensitive than CDU in assessment of plaque surface (for smooth plaques CDU 89% : MSCTA 97%; for plaques with irregular surface CDU 75% : MSCTA 87%; for ulcerations CDU 54% : MSCTA 87%). Regarding determination of plaque structure (mixed plaque CDU 66% : MSCTA 70%; correlation with HP findings CDU 94% : MSCTA 96%) and localization (CDU 63% : MSCTA 65%), and in terms of sensitivity and specificity, both methods showed almost the same results. Also, there is no statistical difference between these two methods for the degree of stenosis (CDU 96% : MSCTA 98%). Conclusion. Atherosclerotic disease of extracranial part of carotid arteries primarily affects population of middle-aged and elderly, showing more associated risk factors. Sensitivity and specificity of CDU and MSCTA regarding plaque composition, the degree of stenosis and plaque localization are almost the same. These results and the fact that there are no adverse effects (high radiation dose) compared to MSCTA indicate that CDU should be the initial method in diagnostic algorythm for carotid arteries.

Introduction: The aim of this research was to compare specifi city and sensitivity of Color Doppler ultrasonographywith CT angiography.Methods: A total of one hundred patients suffering from carotid artery disease (n=200) were tested in this research in the period from June till October, 2011. Average age of the patients was 61.5 years, and most of the patients were in the age group ranging from 55 to 65 years. The level of carotid artery stenosis is measured according to Standards of the North America Symptomatic Carotid Endarterectomy Trail study,by method of Color Doppler ultrasonography and CT angiography.Results: Stenosis <50% registered by Doppler ultrasonography was found in 62% and by CT angiography in 64% patients. Stenosis from 70 to 79% registered by Doppler ultrasonography was found in 88% and by CT angiography in 82% patients. In patients with level of stenosis 70-79% there was a tendencyof registering the stenosis to be higher by Color Doppler ultrasonography, than by CT angiography. In the case of the occlusion, there was also the similar observation, with variation of 8% carotid arteries.Conclusion: Extracranial Doppler and color duplex ultrasound enable reliable detection of both stenosis and occlusion of carotid arteries and accordingly they occupy an important place in radiological algorithm. When it comes to CT angiography it can be concluded that it can provide accurate and exact information regarding the condition of blood vessels as good as Digital Subtractive Angiography can.
