Abstract

Background: Abdominal MSCT examination is a type of radiodiagnostic examination that uses the MSCT device. Considering that the abdomen is close to organs that have radiosensitive properties such as the gonads and ovaries, it is necessary to monitor the radiation dose received so that it does not exceed the predetermined I-DRL value. The prevalence of contrast Abdominal MSCT examinations in the Radiodiagnostic Installation at Dr Hasan Sadikin Bandung Hospital was recorded during the last 3 months, there were 327 Contrast Abdominal MSCT examinations out of a total of 880 examinations with a percentage of contrast Abdominal MSCT examinations of 0.37%. This proves that contrast Abdominal MSCT examinations are often carried out but evaluation has never been carried out regarding the radiation dose received by the patient. Method: The type of research used in this research is descriptive quantitative with an observational approach by collecting data from patients with contrast Abdominal MSCT examinations during the period January-March 2023 with a sample of 128 patients. The local DRL value is calculated using the 2nd quart formula in the SPSS statistical application, then this local DRL value is compared with the I-DRL value determined by BAPETEN. Results: Calculation of the 50th percentile value of CTDIvol and DLP on 128 samples. The results show a CTDIvol value of 15.91 mGy and DLP of 740 mGy*cm. The DRL (50 percentile) values ​​based on gender are 13.71 mGy and 743 mGy*cm for men, and 17.74 mGy and 792 mGy*cm for women. Based on abdominal thickness, patients with a thickness of 10-19 cm have values ​​of 12.19 mGy and 587 mGy*cm, while patients with a thickness of 20-30 cm have values ​​of 22.57 mGy and 965 mGy*cm. For the most clinical cases (Ca Recti) the values ​​were 11.27 mGy and 586 mGy*cm. Conclusion: The 2nd quartile value (50 percentile) of CTDIvol and DLP received by patients during the Contrast Abdominal MSCT examination at the Radiodiagnostic Installation of RSUP Dr. Hasan Sadikin Bandung is in accordance with the standard values ​​set by BAPETEN/I-DRL 2021. However, special attention is needed for patients with an abdominal thickness of 20-30 cm, where the CTDIvol value exceeds the standards set by BAPETEN/I-DRL 2021.

Abstract

Background: CT scans are used for various types of examinations such as examinations of the head, thorax, abdomen and so on. The most frequently performed CT scan is a CT scan of the head. However, in the medical field, especially radiology, CT scans have the highest dose compared to other radiation equipment. Efforts to reduce radiation doses and radiation effects are by estimating the correct dose given to CT Scan patients using an optimization index called DRL (Diagnostic Level Reference), namely by evaluating the values ​​of CTDIvol and DLP on CT scans of the head, which have been determined in accordance with BAPETEN/I-DRL 2021 standards. Method: This research is a descriptive quantitative study with an observational approach which aims to analyze CTDIvol and DLP values ​​based on retrospective data on non-contrast brain CT scans at the Radiology Installation at Hospital X, Central Jakarta. Results: Calculation of the 2nd quartile (50th percentile) value of CTDIvol and DLP in Adult Non-Contrast Brain CT Scan examinations for the January-December 2022 Period at the Radiology Installation at X Hospital, Central Jakarta is CTDIvol 55.51 mGy and DLP 867.00 mGy* cm. Conclusion: The 50 percentile value of CTDIvol and DLP in the Adult Non-Contrast Brain CT Scan examination for the January-December 2022 period at the Radiology Installation at X Hospital, Central Jakarta is in accordance with the standards set by BAPETEN/I-DRL 2021. Where is the value for CT Non-Contrast Head Scan, namely a CTDIvol value of 60 mGy and a DLP value of 1275 mGy*cm.
