However, there is no relevant literature to support the use of CTA chest in a hemodynamically unstable patient with blunt trauma and possible cardiac injury. CTA Coronary Arteries The lack of evidence does not support the use of CTA coronary in a hemodynamically unstable patient with blunt trauma and possible cardiac injury, but it could be done if clinically indicated. FDG-PET/CT Heart There is no relevant literature to support the use of FDG-PET/CT in a hemodynamically unstable patient with blunt trauma and possible cardiac injury. MRI Heart Function and Morphology There is no relevant literature to support the use of CMR function and morphology in a hemodynamically unstable patient with blunt trauma and possible cardiac injury. MRI Heart With Function and Inotropic Stress There is no relevant literature regarding the use of CMR stress in a hemodynamically unstable patient with blunt trauma and possible cardiac injury. MRI Heart With Function and Vasodilator Stress Perfusion There is no relevant literature regarding the use of CMR stress in a hemodynamically unstable patient with blunt trauma and possible cardiac injury. Radiography Chest Bedside anteroposterior (AP) chest radiographs are commonly used as a first-line imaging modality in the evaluation of blunt thoracic trauma at most level I trauma centers in the United States, especially in hemodynamically unstable patients [26,60]. AP chest radiographs have limited ability to identify the direct findings of blunt cardiac injuries such as cardiac rupture, coronary artery dissection, pericardial tear, and valvular injuries. However, radiographs have the potential to identify indirect findings that infer cardiac or pericardial injuries. These indirect findings include hemothorax, widened mediastinum, enlarged cardiomediastinal silhouette, abnormal cardiac silhouette contour, changing cardiac position after tube thoracotomy, pneumopericardium, and displaced rib fractures, especially between the third and ninth ribs.
