We present PET findings of a case of a transient ischemic attack which later progressed to cerebral infarction. Cerebral blood flow at the stroke focus in the right parietal cortex measured after a TIA attack and before stroke was as low as 24 ml/100 g/min with some increase in oxygen extraction fraction and blood volume. The condition was compatible with "misery perfusion". This case may be an example suggestive that the "misery perfusion sign" is a warning of impending stroke and its poor prognosis if left without appropriate treatments.
我们展示了一例短暂性脑缺血发作（TIA）后进展为脑梗死病例的正电子发射断层扫描（PET）结果。在TIA发作后且卒中发生前测量的右侧顶叶皮质卒中病灶处的脑血流量低至24毫升/100克/分钟，同时氧摄取分数和血容量有所增加。这种情况符合“灌注不良”。该病例可能提示“灌注不良征象”是即将发生卒中的警示信号，若不进行适当治疗则预后不良。
