Background/introduction
Radiation safety is one of the most emerging issues in radiology.
Computer tomography is responsible for a large amount of radiation exposure to patients,
but due to its availability and versatile practical applications,
it is an indispensable diagnostic tool.
Thus it is important to monitor and analyze patient dose levels by incorporating different local regulators.
Following the requirements of the latest EU BSS directive [1],
it is vital to create local institutional protocols to standardize the imaging procedures,
and where appropriate,
establish diagnostic reference levels....
Description of activity and work performed
Diagnostic reference levels were established from dosimetric data collected throughout 12 months.
In this poster we present the most common CT protocols used at our institution and their frequency.
( Fig. 1 ,
Fig. 2 )
During the study duration (between June of 2017 and June of 2018) CT scans were performed on 12434 and 6903 patients with a GE BrightSpeed S 16 slice (Scanner1) scanner and a Siemens SOMATOM Definition AS 64 slice (Scanner2) scanner,
respectively.
Our own dose management software automatically collects dosage...
Conclusion and recommendations
The establishment of local DRLs for CT examinations is essential to create national diagnostic reference levels.
Their use in everyday practice will allow us to detect critical issues and help to optimize procedures.
