Comparative Research of B-flow and CDFI in the Diagnosis of Carotid Artery Disease

Objective To compare the application of two-dimensional gray-scale blood flow imaging techniques( B-flow) and Color Doppler Flow Imaging( CDFI) in the carotid artery disease and to explore diagnostic value of B-flow in the carotid artery disease. Methods 100 cases with suspected carotid artery disease were performed CDFI and B-flow respectively check. Vascular contorts,shape,blood vessel wall and blood flow state,measurement of carotid stenosis were observed. In which 32 cases with carotid stenosis took digital subtraction angiography( DSA) inspection. Results B-flow performance in less than 0. 2cm in diameter small patches,vulnerable plaques,blood clots,complex blood flow and carotid artery contorts the anomaly detection were better than that of a CDFI. Carotid stenosis rate comparison between B-flow and CDFI showed statistically significant difference( P 0. 05). Conclusion B-flow in the diagnosis of carotid artery Small plaque,vulnerable plaques,blood clots,complex blood flow and artery contorts the anomaly has more accuracy and superiority than CDFI has.
