CT perfusion is a new technique that is rapid, available and minimally invasive which provides functional vascular information and can be made after conventional CT and CT angiography at the same imaging session. CT perfusion applications have focused on ischemic stroke with only a short series of applications to brain death diagnosis. Instead, CT angiography is frequently performed as a confirmatory test of brain death, but it has not been completely validated yet. Hence CT perfusion may help in supporting the diagnosis of brain death. We present the case of a 12-year-old child with clinical criteria for brain death who required a confirmatory test. CT angiography and CT perfusion were performed. Both revealed the absence of any intracranial blood flow which supported the clinical diagnosis of brain death.
CT灌注是一项新技术，它快速、可行且微创，可提供功能性血管信息，并且能在同一次成像检查中于常规CT和CT血管造影之后进行。CT灌注的应用主要集中于缺血性中风，仅有少量应用于脑死亡诊断。相反，CT血管造影经常作为脑死亡的确诊检查，但它尚未得到完全验证。因此，CT灌注可能有助于支持脑死亡的诊断。我们报告一例12岁符合脑死亡临床标准且需要确诊检查的患儿。进行了CT血管造影和CT灌注检查。两者均显示颅内无血流，这支持了脑死亡的临床诊断。
