摘要
目的计算机体层摄影(computed tomography,CT)是临床诊疗中重要的检查手段,但是其适应症在不同医院存在较大差异,因此需要研究如何更合理使用这种设备。方法采用文献检索、电话调查、问卷调查、报表收集等方法进行调查评估,然后将获取的数据进行统计分析。结果纳入本次研究的武汉市医院49家,拥有共计74台CT设备。根据各大医院使用结果,CT平扫与CT增强检查部位的频次存在明显差别;其中在"全身、CT介入"受检部位中,增强CT使用明显较高,而在"头部、胸部、腹部、脊柱、骨盆、四肢"受检部位中,CT平扫使用更多。不同受检部位的CT平扫与增强检查项目中,男女性别无明显差异,而年龄段构成存在明显差异。结论 CT扫描在武汉各大医院被广泛使用于检查几乎患者身体所有部位,不同的检查手段在不同部位的使用频率存在明显的差别,不同性别患者的应用频率没有差异,但是不同年龄层的使用存在差异。因此不同医疗机构可以根据本院收治病种特点,针对性进行资源配置,提高设备的使用率。
Objective Computed tomography（ CT） is an important examination method for diagnosing,but its indication vary among hospitals. Therefore,we should investigate the rational use of CT scan. Methods Literature searches,telephone surveys,reports were employed to investigate the usage of CT scan,and the data were collected and analyzed. Results Totally 49 hospitals with 74 CT systems in Wuhan were included in this research. According to the usage of all CT systems,we found the non-enhanced and enhanced CT systems were distinctly adopted in different organs. Specifically,enhanced CT scans were more used in the whole body and interventions,while non-enhanced scan were more used in head,thorax,pelvis and limbs. The patients receiving CT scan were of no differences in genders,but varies in age groups. Conclusion CT scan is widely used in Wuhan for almost all body of patients,but the character of use varies in body parts and age groups. So the layout of CT systems should be different in hospitals based on the character of admitted patients.
