Patients with successful cardiopulmonary resuscitation (CPR) will be transferred to the emergency intensive care unit for further standardized management. After successful return of spontaneous circulation (ROSC) for 72 hours and hemodynamic stability for 24 hours, the patients underwent positron emission computed tomography (PET-CT) examination after resuscitation. The supervising physician accompanied the patient and used monitors to monitor vital signs during the examination. Patients who were on ventilators were mechanically ventilated with a magnetic ventilator (HAMILTON-MRI, United States). In addition to conventional cerebral oxygen metabolism, cerebral blood flow, oxygen extraction fraction, cerebral blood volume and other indicators were added in this experiment. These indicators can evaluate the patient's cerebral metabolism, cerebral blood flow and cerebral blood oxygen damage degree. The neurological outcome was followed up 6 months after onset according to the cerebral performance category（CPC）.",[57,58],"Cardiac Arrest","Brain Injuries",[60,61,62,63,64],"Cardiac arrest","Positron Emission Tomography-Computed Tomography","cerebral metabolism","cerebral blood flow","cerebral oxygenation","NOT_YET_RECRUITING","2025-04-10",{"date":68,"type":69},"2025-04-11","ACTUAL",{"date":71,"type":52},"2025-05-01",{"date":73,"type":52},"2027-12-31",{"name":5,"class":6},1]
