Mean (± SE) values of cc-TQ, sas-TQ, MTT, CBV, CBF, TTP and PSV before and after acetazolamide challenge in hemisphere ipsilateral and contralateral to stenosis. Patient population with cc-TQ ipsilateral/contralateral ratio ≥1 (n = 10).

$p#p##p*p**p***pNSnot statistically significant, acetazolamide challenge versus baseline.cc-TQ–pial artery pulsation (cardiac component of the transillumination quotient); sas-TQ–the subarachnoid width (subarachnoid component of the transillumination quotient); MTT–mean transit time; CBV–cerebral blood volume; TTP–time to peak; PSV–peak systolic velocity; SE–standard error; ml–millilitres; g–gram; min.–minutes; s–seconds; cm–centimetres.

NS：无统计学意义（not statistically significant），指代乙酰唑胺激发试验与基线状态的对比结果。cc-TQ：软脑膜动脉搏动（透光商（transillumination quotient）的心脏组分）；sas-TQ：蛛网膜下腔宽度（透光商的蛛网膜下腔组分）；MTT：平均通过时间（mean transit time）；CBV：脑血容量（cerebral blood volume）；TTP：达峰时间（time to peak）；PSV：收缩期峰值流速（peak systolic velocity）；SE：标准误（standard error）；ml：毫升（millilitres）；g：克（gram）；min.：分钟（minutes）；s：秒（seconds）；cm：厘米（centimetres）。
