Elementary Evaluation of Multiple Slice Spiral CT Angioraphy in Carotid Artery

Objective To analyze imaging feature of multislice spiral CT(MSCT)in diagnosis of carotid artery diseases and to evaluate it’s dianostic significance.Methods MSCTA in 80 cases were performed in our study,of them,15 patients were undergone DSA simultaneous.The imaging quality of MSCTA was evaluated and the accuracy of MSCTA in diagnosis of carotid artery diagnosis by comparing the results of CTA and DSA in the same one patient.The calcifications in vessel wall displayed by various CTA reconstruction technique were analysed.Results The results of DSA and MSCTA 60 branches of carotid artery were analysed comparatively.The specificity and sensitivity of MSCTA in diagnosis of carotid artery stenosis was 85.71% and 92.7% respectively,the negative value was 95%,Kappa value was 0.81.Furthermore,CTA could display the artery wall well,it was easy to acquire good imaging quality.Conclusion As one noinvasive method of examination,CTA will play a common role in diagnosis of carotid artery disease.
