Value of Low-dose Multi-slice CT in Application of Craniofacial Trauma

Objective To explore the different low-dose CT scanning of the craniofacial trauma of application value.Methods 60 cases of craniofacial trauma patients were divided into one group of conventional-dose group of line scan and 3 different low-dose CT scan,the conventional dose group(120 kV,220 mA),low dose group (120 kV,60,80 ,60 mA) compared the level 4 group of patients with image quality and radiation dose received. Results The low-dose (160,100 mA) CT scan obtained better CT image,patients of 60 mA group received a lower radiation dose. Group single-scan dose index weights were reduced 33%,67% and 73% respectively; There was no significant differences between low-dose group(160,80 mA) and the normal group,while there was significant differences between the group of 60mA and normal group. Conclusion The use of low-dose (80 mA) for craniofacial trauma scan images obtained from the diagnosis and treatment of disease has no bad effect.
