Two protocols were developed to study the efficacy of both chest radiography and dynamic computed tomography (CT) of the thorax in screening for traumatic aortic injury. Both protocols demonstrated a definite role for dynamic CT in excluding aortic injury in patients with normal initial chest radiographs. The authors studied 164 patients, and preliminary results indicated a high reliability for this method. Their algorithm, with 6-month follow-up, yielded both 100% sensitivity and a 100% negative predictive value. Unnecessary aortography, with its associated morbidity and cost, was decreased by 73%.
制定了两项方案，以研究胸部X线摄影和胸部动态计算机断层扫描（CT）在筛查创伤性主动脉损伤中的有效性。两项方案均表明，动态CT在排除初次胸部X线片正常的患者的主动脉损伤方面具有明确作用。作者研究了164例患者，初步结果表明该方法具有很高的可靠性。他们的算法在6个月的随访中，敏感性和阴性预测值均为100%。与主动脉造影相关的发病率和费用，不必要的主动脉造影减少了73%。
