Investigation on diagnostic value of multi-slice spiral CT angiography in vertigo caused by cervical vascular lesions

目的探讨多层螺旋CT脑血管成像(MSCTA)在颈部血管病变中的诊断价值。方法经128层螺旋CT颈部血管成像检查并且确诊颈部血管病变引起眩晕的100例患者,重建得到多平面重建(MPR)、曲面重建(CPR)、容积再现技术(VRT)和最大密度投影(MIP)图像,综合诊断颈部血管病变,并与临床检查结果进行对比。结果 100例颈部血管病变引起眩晕患者经MSCTA检查,46例颈动脉病变,其中颈内动脉硬化伴局限狭窄26例、颈动脉和分支动脉硬化7例、颈外动脉硬化合并局限狭窄13例;椎动脉损伤88例:椎动脉局部狭窄65例、全狭窄15例、椎动脉横突孔病变8例。上述结果和临床检查结果相同。结论 MSCTA是安全、全面、迅速、无创的检查方法 ,能够被当成颈部血管病变筛查的首选。

Objective To investigate the diagnostic value of multi-slice spiral CT angiography(MSCTA)in vertigo caused by cervical vascular lesions.Methods There were100cervical vascular lesions induced vertigo patients diagnosed and confirmed by128slice spiral CT angiography.The multiplanar reconstruction(MPR),curved planar reformation(CPR),volume rendering technique(VRT)and maximum intensity projection(MIP)images were used to reconstruct the neck vascular lesions,and the results were compared with the clinical findings.Results In100cervical vascular lesions induced vertigo patients,there were46cases of carotid artery lesions by MSCTA,including26cases of internal carotid atherosclerosis complicated with localized stenosis,7cases of carotid and branch artery sclerosis,13cases of carotid artery sclerosis complicated with localized stenosis.There were88vertebral artery injury cases:65vertebral artery stenosis cases,15total stenosis cases,and8vertebral artery transverse hole lesion cases.The above results were identical with the clinical findings.Conclusion MSCTA is safe,comprehensive,rapid,noninvasive method of examination,can be used as a choice for screening of cervical vascular disease.
