Abstract

Diffusion-weighted (DW) MR imaging usually identifies acute cerebral infarction injury in symptomatic patients. We report a patient with severe hypoxic brain injury following suicide attempt by hanging, but with normal DW MR imaging 5-6 h after the event. Follow-up DW MR imaging 3 days after the event, and subsequent autopsy, revealed extensive cerebral anoxic injury.

摘要

扩散加权磁共振成像（DW-MRI）通常能在有症状的患者中识别急性脑梗死损伤。我们报告了一名患者，其在自杀未遂上吊后出现严重缺氧性脑损伤，但事件发生5至6小时后DW-MRI成像结果正常。事件发生3天后的随访DW-MRI成像以及随后的尸检显示存在广泛的脑缺氧损伤。
