目的 前瞻性分析3.0T应用SENSE技术的高分辨率对比增强容积扫描MRA(CEMRA)和3DTOFMRA在临床疑有颅、颈部动脉狭窄性病变患者中的应用价值.方法 46例临床怀疑颅、颈部动脉狭窄的患者接受头颅MRI平扫、头颅3DTOFMRA和颈部CEMRA检查.动脉狭窄的程度与DSA检查结果进行相关性比较.结果 MRA显示各段颅、颈部动脉狭窄的不同程度和DSA检查显著相关(Rs=0.97,P<0.01).以DSA结果为金标准,狭窄程度超过50%者MRA诊断灵敏度为100%,特异度为99.4%、准确率为99.4%.结论 3.0T的3DTOFMRA和高分辨率CEMRA检查能可靠和有效地评价颅、颈部动脉狭窄性病变,可作为DSA术前必要的检查技术,或可替代传统DSA诊断性检查.
