| 目的 探讨螺旋CT血管造影(SCTA)检查颅外颈动脉狭窄的准确性以及用SCTA代替数字减影血管造影(DSA)的可能性。方法 本组研究采用NASCET标准对照比较SCTA 与DSA 的颈动脉血管造影结果,并参考部分病例的手术所见,以分析SCTA 检查颅外段颈动脉狭窄的准确性。结果 本组29 例患者的33 个颈动脉狭窄中,SCTA对照DSA的诊断总符合率为87.9 % .其中严重狭窄组的相符率为100 % .结论 SCTA不仅对颈动脉狭窄程度的诊断有很高的准确性和直观性,而且能够显示DSA 难以发现的附壁钙化以及血栓。有望取代DSA 在颈动脉狭窄诊断中的地位。 |

| Objective To study the accuracy of spiral CT angiorgraphy (SCTA) in the assessment of stenosis in the extra cranial portion of carotid artery and the possibility of this technique in the replacement of DSA.Methods Spiral CT images of 33 carotid stenoses were compared with DSA in order to assess degree of stenosis using the NASCET guide lines.Results The degree of carotid artery stenosis on the SCTA correlated well with that of DSA in 29of 33 stenoses (87 9%).The presence of severe stenosis or occlusion was correctly identified in 6 of 6 cases(100%).Conclusion SCTA is an accurate blood vessel detection method which will replace DSA in the assessment of atherosclerotic carotid stenosis. |
