高场强3D CE-MRA在脑卒中筛查中的应用研究

The applied research of three dimensional contrast enhanced magnetic resonance angiography in stroke screening

高场强3DCE-MRA在诊断脑卒中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。通过对经行颈动脉彩超检查临床怀疑颈动脉狭窄的脑卒中患者行高场强3DCE-MRA及DSA检查的比较研究,并以DSA为标准,结果两种检查方法在颈动脉血管狭窄评估方面取得高度一致性,验证了高场强3DCE-MRA其在脑卒中筛查中的的应用价值。

High-field-strength 3D CE-MRA has a high sensitivity,accuracy and specificity in the diagnosis of stroke of extracranial carotid stenosis lesions,and can be used for screening of suspicious of extracranial carotid artery stenosis or occlusion of the patients.Make most patients absolve DSA checks.Comparative study of 3D CE-MRA and DSA which by color doppler ultrasound examination of the carotid clinical suspected the carotid stenosis stroke patients line,DSA as standard.The results of two methods to achieve a high degree of consistency in the carotid artery stenosis assessment,verify the value of the high-field-strength 3D CE-MRA stroke screening.
