Table 3 Diagnostic strength of computed tomography in detecting acute myocardial infarction and predicting poor neurological outcome

From: Clinical experience of whole-body computed tomography as the initial evaluation tool after extracorporeal cardiopulmonary resuscitation in patients of out-of-hospital cardiac arrest
