Investigation and analysis of the CT scan in radiation diagnosis unit of Wuhan in 2015

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. (authors)
