Description of activity and work performed
Objective: The purpose of this study was to establish diagnostic reference levels (DRLs) in general radiology,
at Clínica Alemana de Santiago,
Chile (CAS).
Material and methods: The information was obtained using the DICOM MPPS (Digital Communications in Medicine-Modality Performance Procedure Steps communication protocol (4)),
which allows to take the DAP (Dose Area Product in Gy * cm2) values from each modality to a RIS -MPPS interface that will receive the data in the RIS system (HL7),
being associated to the study in the RIS system database for a historical record,
The data collected was processed with Oracle Business Intelligence.
(Figure 1).
Data were collected from October 2017 to March 2018 for 60 different protocols,
subclassified by age ranges.
The DRLs were calculated from the DAP values delivered from the radiological equipment.
For comparable examinations (7 exams),
the values obtained were compared with those published by the United Kingdom in 2016 (5).
RESULTS: There are no DRLs in Chile,
so we compared those obtained at Clínica Alemana with updated information from the UK.
