title: [Computed tomography of lung contusion. An experimental study].
abstract: A new experimental model has been developed to determine whether computed tomography has any advantages for the investigation of lung contusions. In 27 dogs, chest wall deformation was produced at speeds varying from 17.3 m/sec to 45.7 m/sec, leading to lung contusion. After the injury, 27 out of 27 (100%) CT examinations demonstrated the contusions, but only nine out of 24 (37.5%) were seen on conventional radiographs. In contrast to conventional radiography, which either failed to show the presence of a contusion, or which under-estimated the extent by more than one cm, in more than half the cases CT agreed with the pathological findings in more than 90%. No lung contusions were found at autopsy which had not been demonstrated by CT.
