PDFAbstract
Objective To investigate the clinical application of multi-slice spiral CTA combined with contrast-enhanced ultrasound (CEUS) in the stability evaluation of carotid plaque. Methods A total of 120 cases of patients with carotid plaque stenosis admitted to our hospital from February 2017 to May 2018 were selected, and they were given carotid CTA and CEUS. The carotid plaque conditions were observed. Results Take DSA the golden standard, the consistency accuracy of CEUS examination was 88.33%, and the sensitivity and specificity were 72.73% and 94.25%, and Kappa=0.70, P<0.05. The accuracy of CTA was 81.66%, and the sensitivity and specificity were 60.00% and 90.59%, and Kappa=0.533, P<0.05. The accuracy of CTA combined with CEUS was 91.67%, and the sensitivity and specificity were 78.79% and 96.55%, and Kappa=0.783, P<0.05. The accuracy, sensitivity, specificity, negative predictive value and positive predictive value of CTA combined with CEUS were higher than those of CTA alone and CEUS alone. Conclusion Multi-slice spiral CTA combined with contrast-enhanced ultrasound has positive effects on carotid plaque stability, and can significantly improve the diagnostic accuracy.
