【摘要】：目的:探讨采用256层CT全脑灌注成像重建的4D-CT血管造影在急性缺血性脑卒中中的价值。方法:自2011年12月至2012年9月,共收集52例急性缺血性脑卒中病患的临床及影像学资料。所有患者均接受入院CT平扫、256层全脑CTP和头颈部CTA检查。CTP动态扫描获得全脑的血流灌注信息,通过灌注原始数据重建获得12cm扫描覆盖范围内的动态4D-CTA,观察其检测大血管管腔状况的能力。结果:CTA共检测11位患者中存在12处颅内血管闭塞。4D-CTA显示颅内11处大血管闭塞,敏感性、特异性及阳性预测值分别为91.7%、100%、100%。结论:256层CT全脑灌注成像重建的4D-CT血管造影可作为检测急性缺血性脑卒中大血管闭塞的一种可行方法。
[Abstract]:Objective: to evaluate the value of 4D-CT angiography with 256-slice CT global cerebral perfusion imaging in acute ischemic stroke. Methods: from December 2011 to September 2012, the clinical and imaging data of 52 patients with acute ischemic stroke were collected. All patients received plain CT scan, 256-slice whole brain CTP and head and neck CTA examination. The blood perfusion information of the whole brain was obtained by dynamic CTP scanning, and the dynamic 4D-CTAs covered by 12cm scan were obtained by the reconstruction of the original perfusion data. The ability of detecting the condition of large vascular lumen was observed. Results: there were 12 intracranial vascular occlusions in 11 patients detected by CTA. The sensitivity, specificity and positive predictive value of 4D-CTA were 91.7100% and 100% respectively. Conclusion: the 4D-CT angiography with 256-slice CT whole brain perfusion imaging can be used as a feasible method for the detection of large vascular occlusion in acute ischemic stroke.
