| 目的 评价CT平扫、CT脑灌注成像和经颅多普勒超声(TCD)检查对短暂性脑缺血发作(TIA)的诊断价值和限度。方法 对20例临床诊断TIA的患者行头颅CT平扫、CT脑灌注成像和TCD检查,对其检查结果进行对比分析。结果 头颅CT平扫可排除其他脑内疾病,CT脑灌注成像显示颅内血流动力学异常改变,TCD则有助于明确TIA的病因。结论 3种影像学方法结合应用,可获取更多的诊断信息,对TIA的诊断和治疗有重要意义。 |

| Objective To evaluate the value and limit of CT plain scan, CT cerebral perfusion imaging and transcranial Doppler (TCD) in transient ischemic attacks (TIA). Methods Conventional CT, CT cerebral perfusion imaging and TCD were performed in 20 patients with TIA diagnosed by clinic. The results were analyzed in a comparison way. Results The head plain scan of CT could excluded other intracerebral diseases,and perfusion CT provided valuable hemodynamic information and showed the extent of perfusion disturbances, however, TCD could demonstrated involved cerebral arteries for patients in TIA. Conclusion The combination of these three imaging methods could obtain more diagnostic information, and the information can play an important role in the diagnosis and treatment of TIA. |
