Pediatric cervical spine injuries on CT: difference in accuracy of interpretations by pediatric versus non-pediatric radiologists
AbstractPurposeTo retrospectively compare the accuracy of interpretation of initial cervical computerized tomography (CCT) by a non-pediatric radiologist (NPR) versus a pediatric radiologist (PR).MethodsIRB approval and consent waiver were granted to review all injured children from 2010 to 2014 in the trauma registry with CT and magnetic resonance imaging (MRI) of the cervical spine. Patients with negative CCT who subsequently had positive MRI from a single institution comprised the study group. Patients with negative CCT and MRI, matched by age, gender, and severity scores, comprised the control group. The CCTs from both...

The resuscitative endovascular balloon occlusion of aorta (REBOA) device —what radiologists need to know
AbstractResuscitative endovascular balloon occlusion of the aorta (REBOA) is a novel device approved by the Food and Drug administration (FDA) in 2017 as an alternative to resuscitative emergent thoracotomy (RET). Due to advancements in placement of REBOA, including newly validated placement using anatomic landmarks, REBOA is now widely used by interventional radiologists and emergency physicians in acute subdiaphragmatic hemorrhage. Increased use of REBOA necessitates that radiologists are familiar with verification of proper REBOA placement to minimize complications. This review describes the REBOA device, indications, p...

However, these clues are difficult to perceive on 2D CT images and can be overlooked.
