Dopamine transporter (DAT) scan is important in the diagnosis of Parkinson's disease (PD). We herein report a patient with vascular parkinsonism (VP) who showed dopamine transporter (DAT) scan findings which mimicked those typically seen in patients with Parkinson's disease (PD). DAT scan findings in patients with VP are characterized by a lower striatal asymmetry index than in patients with PD and decreased uptake in the area consistent with old cerebral infarction or hemorrhage. However, we should be aware that, as in our patient, VP patients with asymmetric basal ganglia lesions, may show increased striatal asymmetry index and asymmetric DAT scan findings.
多巴胺转运体（DAT）扫描在帕金森病（PD）的诊断中很重要。我们在此报告1例血管性帕金森综合征（VP）患者，其多巴胺转运体（DAT）扫描结果与帕金森病（PD）患者典型所见相似。VP患者的DAT扫描结果特点是纹状体不对称指数低于PD患者，且在与陈旧性脑梗死或出血相符的区域摄取减少。然而，我们应该意识到，正如我们的患者一样，有不对称基底节病变的VP患者可能会出现纹状体不对称指数增加和DAT扫描结果不对称的情况。
