Abstract:
Objective To discuss the application of self-developed novel 16-slice mobile CT head scan.Methods A total of 391 patients were performed 16-slice mobile CT scan:145 were scanned in the emergency department,156 in the neurosurgical ICU,55 in the operated room,and 35 in the ambulance vehicle.Sixty-eight patients were with brain injury,122 were with cerebral hemorrhage,120 were with cerebral infarction,59 were with brain tumors,and 22 were with hemifacial spasm.Thirty-five patients were randomly selected from 391 patients and 8-slice mobile CT head scan was performed on them,which included 12 with brain injury,6 with cerebral hemorrhage,12 with cerebral infarction,3 with brain tumors and 2 with hemifacial spasm.The resolution,imaging quality,radiation doses,power consumption and performance stability of novel 16-slice mobile CT and 8-slice mobile CT head scan were compared.Results The resolution line pairs of brain tissues were 91 p/cm by 16-slice mobile CT and 71 p/cm by 8-slice mobile CT,respectively.The imaging quality of the two kinds of mobile CT head scans was high level to the clinic diagnostic criteria.The radiation dose of 16-slice mobile CT were 40.43 mGy,which decreased by 51.01％ as compared with that of 8-slice mobile CT (82.52 mGy).The personal power consumption of 16-silce mobile CT (0.29 kW· h) decreased by 38.30％ as compared with those of 8-layer mobile CT (0.47 kW· h).The 16-slice mobile CT kept regularly,while 8-slicer mobile CT stopped to work twice during clinical trial.Conclusion The 16-slice mobile CT scan has high resolution,fine imaging quality,low radiation dose,small power consumption and stable working performance.
