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90 059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10 969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90 059例次,其中急诊室82 843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10 959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 90 059 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 10 969 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 90 059 cases of 8-slice mobile CT head scanning, including 82 843 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 10 959 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 cost and low radiation dose. It has a variety of imaging functions such as plain scanning, enhancement and CTA and CTP.
