颅外颈动脉螺旋CT血管造影的临床意义(附45例报告)

目的 报告颅外颈动脉ＣＴ血管造影（ＣＴＡ）的初步经验，探讨该技术对各种颅外颈动脉病变的诊断意义，并在可能范围内与数字减影血管造影（ＤＳＡ）作小样本的对照。方法 ４５例颈动脉ＣＴＡ，经最大密度投影（ＭａｘＩＰ）及表面灰度成像法（ＳＳＤ）行三维重建，其中５例在１周内作了ＤＳＡ检查。结果 ４５例颈动脉ＣＴＡ检查，共得到９０支血管图像。其中正常血管５５支，狭窄血管３１支，闭塞血管２支，颈内动脉动脉瘤１支，

Spiral CT angiography of extracranial carotid artery (report of 45 cases)

Objective To evaluate spiral computed tomography(CT) angiography in the diagnosis of extracranial carotid artery disease. Methods Fortyfive patients referred for evaluation of carotid artery diseases were studied. Beginning with editing the source images threedimensional MaxIP and SSD images were reconstructed. Of the fortyfive patients, five had digital subtraction angiography (DSA) examination within one week time. Results CT angiography of extracranial carotid artery demonstrated 55 normal vessels, 31 stenotic vessels, 2 occluded vessels, 1 internal carotid aneurysm, and 1 carotid body tumor. The diagnosis of the five patients who had DSA examinations correlated well with CT angiography. Conclusions CT angiography can noninvasively provide most of the information about carotid artery disease at its bifurcation.
