320排动态容积CT血管造影对眼动脉起源的观察
320-Detector Row Computed Tomography Angiography of Origin Ophthalmic Artery
摘要
Abstract
[Objective] To investigate the anatomical and clinical significance of 320-detector row CT angiography of the abnormal origin ophthalmic artery.[Methods] 66 patients underwent 320-detector row CT angiography.The obtained thin-slice images were reformatted by using maximum intensity projection,curved planar reformation and volume rendering to evaluate ophthalmic artery.The origin and variation of the ophthalmic arteries were assessed.[Results] The ophthalmic artery of 120 sides arose from internal carotid artery,and respectively originated from the terminal,supraclinoid,siphonate,cavemous,petrous segment of internal carotid artery.4 sides originated from the middle meningeal artery.The ability in detecting the ophthalmic artery origin by MPR,CPR,MIP and VR was near same,and the relation of the root of the ophthalmic artery and internal carotid arteries were shown well.[Conclusion] 320-detector row CT angiography could accurately demonstrate the origin and variation of the ophthalmic artery,therefore it is helpful to provide anatomic basis for imaging diagnosis,interventional therapy and surgery by studying the anatomy of ophthalmic artery.关键词
