Introduction: There is much controversy over whether or not to use CT scan in patients with minortraumatic brain injury. The present study was conducted aiming to examine the results of CT scan inminor traumatic brain injury on the basis of the required indications and final clinical results.Methods: A cross sectional study, the present study was conducted in the emergency section of NamaziHospital, Shiraz, Iran. Patients with traumatic brain injury and Glasgow Coma Scale scores 13 to 15 wereincluded. The clinical and CT scan results of patients were collected, compared and analyzed using SPSSsoftware. P-values less than 0.05 were regarded as significant.Findings: Out of 263 patients, 182 (62.6%) and 81 (30.8%) were male and female, respectively. Also, themean age of participants was 21.36±21.79. The most prevalent indication in patients was vomiting(56.3%) and the most prevalent unnatural indication was linear skull fracture. The present study reportedthat there is a significant association between unnatural CT scan results and indications of loss ofconsciousness level (P<0.01), headache (P=0.01) and post trauma seizure (P=0.04).Conclusion: The present study came to the conclusion that the four indications, namely, consciousnesslevel, headache, post trauma seizure and vomiting can well predict the necessity for using CT scan inpatients with minor traumatic brain injury.
