[MSCT optimal examination time for unconspicuous rib fracture].

OBJECTIVE

To explore MSCT optimal examination time for patients with unconspicuous rib fracture.

METHODS

Sixty-three patients with thoracic trauma from January 2009 to June 2011 were collected. They were examined by MSCT in the first week after trauma and re-examined during eighth weeks after trauma. The number of rib which had been found fractured in the first examination was compared to that in re-examinations.

RESULTS

Patients with fine rib fracture often have different diagnostic results at different examination time after trauma. There was statistical difference between the number in the first week and the third week to the fifth week.

CONCLUSION

MSCT could show the pathophysiological changes of rib fracture objectively in the stage between the third week and the fifth week after trauma, which is optimal examination time for the fine rib fracture.
