Abstract
ObjectiveTo discuss the application of self-developed novel 16-slice mobile CT head scan.
MethodsA 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.
ResultsThe resolution line pairs of brain tissues were 9l p/cm by 16-slice mobile CT and 7l 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.
ConclusionThe 16-slice mobile CT scan has high resolution, fine imaging quality, low radiation dose, small power consumption and stable working performance.
