However severe residual neurological impairment such as persistent coma occurs in some survivors. This raises concerns about whether it is ethically appropriate to apply aggressive care routinely which is also associated with burdensome long-term management costs. Adapting the management approach based on long-term neurological prognosis represents a major challenge to intensive care. Magnetic resonance imaging MRI can show brain lesions that are not visible by computed tomography including early cytotoxic oedema after ischaemic stroke diffuse axonal injury after traumatic brain injury and cortical laminar necrosis after cardiac arrest. Thus MRI increases the accuracy of neurological .
