彩色多谱勒扫描和多谱勒能量扫描诊断颈动脉狭窄的对比研究

Stenosis of Internal Carotide Artery Assessted by Color and Power Doppler Imaging

目的 :对比彩色多谱勒扫描 (CDI)和多谱勒能量扫描 (PDI)诊断颈动脉狭窄的准确性和有效性。材料和方法 :对 96例颈动脉分别用 CDI、PDI检查 ,并对结果进行评估。结果 :在发现靶血管的能力上 ,PDI优于 CDI;对病变区域血流的扫描 PDI明显优于 CDI,在病变血管的病理改变检查方面两者无明显差异。结论 :PDI是一个很好的辅助检查方法 ,在某些情况下 ,可提供有价值的信息 ,但 PDI不能代替 CDI。

Objective To compare the adventages and limitations of PDI and CDI in the evaluation of internal carotid artery stenosis. Methods 96 cases patients were included in this study. All subjects were examined with CDI and PDI. The diagnostic accuracy and overall efficacy were evaluated. Results PDI was significantly superior to CDI in identifing the target vessel and in evaluating blood flow. There were no significant differences in determining the causal pathology. Conclusion PDI is a good additional method to CDI. Combined use of the two methods will lead to a diagnostic accuracy that cannot be achieved by either method along.
