title: Thoracic aortic trauma: role of dynamic CT.
abstract: 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%.
