Abstract
Background
The Indonesian government has established a national dose reference in the form of Indonesian Diagnostic Reference Levels (IDRLs) published in 2021 However, for the implementation of this IDRL to be effective, each clinical practice needs to conduct a routine evaluation of the doses received by patients and compare them with the latest Indonesian Diagnostic Reference Levels (IDRL).
Aim
This study aims to evaluate the CTDI-vol and DLP values in adults during the Chest CT scan examinations at the Sanjiwani Hospital Gianyar and compare them with the Indonesian Diagnostic Reference Levels (IDRLs) 2021.
Methods
This study is a descriptive quantitative study conducted with a survey to evaluate the CTDI-vol and DLP values on the Non-contrast Chest CT Scan examination in adult patients (> 15 years) at Hospital Gianyar. Data were collected retrospectively through digital archives in patients’ folders. The data regarding patients’ gender and age, examination protocols and parameters, and radiation dose in the form of CTDI-vol and DLP, were collected in this study.
Results
A total of 93 adult non-contrast Chest CT Scan examinations were collected in this study, consisting of 58 male and 35 female patients. The 75percentile value for CTDI-vol and DLP for non-contrast Chest CT scan examination at Sanjiwani Hospital Gianyar is 5.33 mGy and 184.2 mGy*cm, respectively.
Conclusion
The facilities’ Diagnostic Reference Levels (fDRL) at Sanjiwani Hospital are still within the tolerance limit set on the Indonesian Diagnostic Reference Levels 2021. However, some examinations fell beyond the CTDI-vol and DLP references.
