目的：探讨能量多普勒诊断烟雾病颅内狭窄和闭塞血管的临床价值。方法：利用ＣＤＥ技术对１７例烟雾病患者的１０２条颅内主要动脉（大脑前动脉ＡＣＡ、大脑中动脉ＭＣＡ、大脑后动脉ＰＣＡ）进行观测，并与ＤＳＡ结果进行对比。结果：ＣＤＥ在诊断烟雾病颅内血管狭窄和闭塞方面具有较高的临床价值，其灵敏度（Ｓｅ）分别为８６．２７％、６６．６７％，特异度（Ｓｐ）９０．２０％、９２．２２％，准确度（Ａｃ）８８．２４％、８９．２２％，假阳性率（α）９．８０％、７．７８％，假阴性率（β）１３．７３％、３３．３３％，阳性预告值（＋ＰＶ）８９．８０％、５３．３３％，阴性预告值（－ＰＶ）８６．７９％、９５．４０％，阳性似然比（＋ＬＲ）８．８０、８．５７，阴性似然比（－ＬＲ）０．１５、０．３６，约登指数（ＹＩ）０．７６、０．５９。结论：能量多普勒在诊断烟雾病的血管闭塞和狭窄方面有较高的临床价值。
Objective: To investigate the clinical value of energy Doppler in the diagnosis of intracranial stenosis and occlusion of moyamoya disease. Methods: A total of 102 major intracranial arteries (ACA, MCA and PCA) of 17 patients with moyamoya disease were studied by CDE technique and compared with DSA results. Results: CDE had high clinical value in the diagnosis of intracranial vascular stenosis and occlusion of moyamoya disease. The sensitivity and specificity of CDE were 86.27%, 66.67% and 90.20%, respectively. (Ac) 88.24%, 89.22%, false positive rate (α) 9.80%, 7.78%, false negative rate (β) 13.73%, 33.33% Positive predictive value (+ PV) 89.80%, 53.33%, negative predictive value (-PV) 86.79%, 95.40%, positive likelihood ratio (+ LR) 8.80,8.57, negative However, the ratio of (-LR) 0.15,0.36, Youden index (YI) 0.76,0.59. Conclusion: The energy Doppler in the diagnosis of moyamoya disease vascular occlusion and stenosis have a higher clinical value.
