| 摘 要： | 目的:评估3D快速黑血管壁磁共振成像(3D T1-SPACE)技术对基底动脉狭窄病变的诊断价值。方法:回顾性分析54例基底动脉狭窄患者的3D T1-SPACE图像和DSA图像。对3D T1-SPACE图像进行评分,并在3D T1-SPACE和DSA图像中测量病变狭窄程度。评价3D T1-SPACE测量结果与DSA测量结果的相关性和信度;使用Bland-Altman图评价3D T1-SPACE测量结果与DSA测量结果的一致性。以DSA为金标准,计算3D T1-SPACE技术诊断基底动脉重度狭窄的一致率、灵敏度、特异度、阳性预测值、阴性预测值、阳性似然比和阴性似然比。结果:54例患者(41例男性,13例女性)均顺利完成基底动脉3D T1-SPACE扫描。54根基底动脉中,剔除2根评分为1分的血管。图像质量评分为(3.14±0.57)分。3D T1-SPACE测得的基底动脉狭窄率(37.80±16.29)%稍大于DSA上测得的狭窄率(37.06±16.17)%,二者比较,差异无统计学意义(P=0.11);两种成像方式的测量结果相关性强(r=0.979,P<0.001);组内相关系数示3D T1-SPACE与DSA对基底动脉狭窄的诊断信度高(ICC=0.99, 95%CI:0.98,0.99,P<0.001);Bland-Altman图示3D T1-SPACE测量结果与DSA测量结果具有高一致性。以DSA为金标准,3D T1-SPACE技术对基底动脉重度狭窄诊断的一致率、灵敏度、特异度、阳性预测值、阴性预测值、阳性似然比和阴性似然比分别为92.3%,85.7%,96.4%,95.5%,90.0%,24.5和0.13。结论:3D T1-SPACE技术对基底动脉狭窄病变具有较高的诊断价值。
