In the United States, approximately 1.7 million patients are treated annually for traumatic brain injury, and cerebrovascular insults are the third leading cause of death. Although CT plays a central role in the initial assessment of suspected intracranial injury, planar brain scintigraphy provides valuable information regarding cerebral perfusion, function, and brain death. An understanding of the complexity of injuries is helpful in scintigraphic image interpretation. To illustrate potential scintigraphic confounders, we present 8 suspected brain death cases with correlative CT. Even with negative brain death studies, severe brain injury by CT portends grave outcomes.
在美国，每年约有 170 万名患者因创伤性脑损伤接受治疗，脑血管损伤是导致死亡的第三大原因。尽管 CT 在疑似颅内损伤的初步评估中发挥着核心作用，但平面脑闪烁成像术提供了有关脑灌注、功能和脑死亡的有价值的信息。了解损伤的复杂性有助于闪烁成像图像的解释。为了说明潜在的闪烁成像混杂因素，我们展示了 8 例疑似脑死亡的 CT 相关病例。即使 CT 检查未显示脑死亡，严重的脑损伤也预示着预后不良。
