摘要 目的探讨零回波时间动脉自旋标记MR血管成像(zTE ASL MRA)技术用于颅内动脉瘤介入治疗效果评估中的临床价值。方法2017年1月至2019年1月该院收治的行介入治疗的颅内动脉瘤患者48例,共计54个动脉瘤。分别行zTE ASL MRA及时间飞跃法MR血管成像(TOF MRA)检查,并在两种检查后的7天内行数字减影技术(DSA)检查,以DSA作为评估金标准。评定两种MRA检查方法对瘤腔残存的敏感度、特异度、阳性预测值及阴性预测值等。结果54个颅内动脉瘤的瘤腔残存,DSA检出26个,TOF MRA检出22个,zTE ASL MRA检出30个。TOF MRA的检出敏感度、特异度、阳性预测值、阴性预测值分别为76.9%、92.9%、90.9%、81.3%,zTE ASL MRA分别为100%、85.7%、86.7%、100%。zTE ASL MRA管腔内显示总评估率91.3%高于TOF MRA的52.2%。结论颅内动脉瘤行介入栓塞治疗术后采用zTE ASL MRA进行疗效评估,较TOF MRA,可更好地评估瘤腔残存、更好地显示管腔内情况。
