16-slice CT angiography versus ultrasonography in cervical artery diseases
Objective To compare the diagnostic results of CT angiography (CTA) and ultrasonography (US) on cervical artery disease and to evaluate the diagnostic value of CTA on cervical artery lesions. Methods A retrospective study was on the results of CTA
US and DSA (digital subtraction angiography) simultaneously performed on 34 patients. Taking the diagnostic results of DSA as standard
those of CTA and US on the cervical artery disease were compared. The diseases of arteries were classified according to the findings from CTA and US to understand the sensitivity
accuracy
specificity
positive predictive value and negative predictive value of CTA and US. Results In a total of 272 vessels of 34 patients

1 by US (totally 150 lesions). Significant difference was found between CTA and US in the detection of cervical artery diseases (P0.05) and CTA had higher sensitivity and specificity than US in the detection of cervical artery diseases. US was unsatisfied in detecting the lesions at the origin of arteries. Conclusion Spiral 16-slice CTA is more reliable than US in evaluating the lesions in cervical arteries due to its high sensitivity and specificity
