摘　　要：目的多中心临床应用对比分析8排及16排移动CT的成像质量及性能特点、检查耗时、人工成本及辐射剂量值等。方法解放军总医院第七医学中心神经外科自2010年8月至2020年7月应用8排移动CT行头部扫描90059例次,解放军总医院第七医学中心神经外科联合多家医院自2017年3月至2020年7月应用16排移动CT行头部扫描10969例次,分别采集患者头部扫描成像、检查时间、人工成本(人员累计耗时),以及辐射剂量值:CT剂量指数(CTDIvol)、剂量长度乘积(DLP)、有效剂量(ED)。另外随机选择同期60例次64排大型CT检测值作为对比。结果(1)成像分析:8排移动CT头部扫描90059例次,其中急诊室82843例次(91.99%)、ICU 7090例次(7.87%)、手术室126例次(0.14%)。16排移动CT头部扫描10959例次,其中急诊室8601例次(78.41%)、ICU 879例次(8.01%)、手术室31例次(0.28%)、车/船/机载头部扫描1458例次(13.29%)。2组成像质量基本相同,与8排移动CT组相比较,16排移动CT安装有精密导轨控制扫描和减振器,扫描速度快,运动伪影少,具有平扫+增强、脑血管造影(CTA)和脑灌注成像(CTP)等多种成像功能。(2)扫描时间与辐射剂量:16排、8排移动CT及64排大型CT的扫描时间、人工成本、辐射剂量(CTDIvol、DLP、ED)比较,差异均有统计学意义(P<0.05)。结论16排移动CT成像质量优良,扫描速度快耗时少、人工成本低、辐射剂量低,具有平扫、增强及CTA、CTP多种成像功能。Objective To compare and analyze the imaging quality and performance characteristics,examination time,labor cost and radiation dose value of 8-silce and 16-slice mobile CT in multi-center clinical application.Methods From August 2010 to July 2020,Neurosurgery Department of the Seventh Medical Center,Chinese PLA General Hospital performed 90059 head scans with 8-slice mobile CT;From March 2017 to July 2020,Neurosurgery Department of the Seventh Medical Center,Chinese PLA General Hospital combined with several hospitals performed 10969 head scans with 16-slice mobile CT.The patients’head scanning,examination time and labor cost(cumulative time of personnel),and radiation dose value were collected:CT dose index(CTDIvol),dose length product(DLP),effective dose(ED).In addition,the detection values of 64 rows of large CT in 60 cases of the same period were randomly selected for comparison.Results(1)Imaging analysis:There were 90059 cases of 8-slice mobile CT head scanning,including 82843 cases in the emergency room(91.99%),7090 cases in the ICU(7.87%)and 126 cases in the operating room(0.14%).There were 10959 cases of 16-slice mobile CT head scanning,including 8601 cases in the emergency room(78.41%),879 cases in the ICU(8.01%),31 cases in the operating room(0.28%),and 1458 cases in the vehicle/ship/aircraft head scanning(13.29%).The imaging quality of the two components is basically the same.Compared with the 8-slice mobile CT group,the 16-slice mobile CT group is equipped with precision guide rail control scanning and shock absorber,with fast scanning speed and less motion artifacts,and with a variety of imaging functions such as plain scanning+enhancement,CT angiography(CTA)and CT perfusion imaging(CTP).(2)Scanning time and radiation dose:There were significant differences in scanning time,labor cost and radiation dose(CTDIvol,DLP,ED)of 16-slice,8-slice mobile CT and 64-slice large-scale CT(P<0.05).Conclusion The 16-slice mobile CT has excellent imaging quality,fast scanning speed and less time consuming,low staff
