Abstract
PURPOSE
We aimed to establish the first diagnostic reference levels (DRLs) for computed tomography (CT)
examinations in adult and pediatric patients in Turkey and compare these with international DRLs.
METHODS
CT performance information and examination parameters (for head, chest, high-resolution CT of
the chest [HRCT-chest], abdominal, and pelvic protocols) from 1607 hospitals were collected via a
survey. Dose length products and effective doses for standard patient sizes were calculated from
the reported volume CT dose index (CTDIvol).
RESULTS
The median number of protocols reported from the 167 responding hospitals (10% response rate)
was 102 across five different age groups. Third quartile CTDIvol values for adult pelvic and all pediatric body protocols were higher than the European Commission standards but were comparable
to studies conducted in other countries.
CONCLUSION
The radiation dose indicators for adult patients were similar to those reported in the literature, except for those associated with head protocols. CT protocol optimization is necessary for adult head
and pediatric chest, HRCT-chest, abdominal, and pelvic protocols. The findings from this study are
recommended for use as national DRLs in Turkey
