| 摘 要： | 目的研究磁共振血管成像技术对急性脑梗死患者颅外段颈动脉狭窄的诊断价值。方法对32例临床怀疑颈动脉狭窄的急性脑梗死患者行磁共振血管成像(magnetic resonance angiography MRA)及数字减影血管造影(digital subtraction angiography,DSA)检查,DSA以NASCET法计算狭窄率,MRA分别以NASCET法和截面积法计算狭窄率。结果以DSA诊断为金标准,32例128条颅外段颈动脉狭窄,MRA以NASCET法诊断的敏感性63%,特异性100%,准确性78.1%,Kappa=0.593;MRA截面积法诊断的敏感性63%,特异性100%,准确性79.7%,Kappa=0.622。结论MRA在诊断急性脑梗死颅外段颈动脉狭窄病变时,具有较高的敏感性、准确性和特异性,可用于筛选可疑颅外段颈动脉狭窄或闭塞的患者,使大部分患者免除DSA检查,但MRA尚不能代替DSA。

| Abstract: | Objective To evaluate the value of magnetic resonance angiography in carotid artery-extracranial segment stenosis of acute cerebral infarction. Methods Magnetic resonance angiography(MRA) and digital subtraction angiography(DSA) were performed in 32 patients with clinical suspected carotid stenosis in acute cerebral infarction patients. Stenosis measurement according to NASCET criteria for DSA was used,and stenosis measurement for MRA according to NASCET and cross section criteria was used. Results The sten... |
