Abstract

Research has been carried out on determining the effective dose of organ at risk for head irradiation using a Siemens 128 slice CT-Scan at Sanglah Hospital, Denpasar. The data used in this study are secondary data from medical records or CT-Scan archives irradiating the head, namely CTDIVOL and DLP data for male and female patients aged 26-45 years. This study aims to determine the amount of DE and Deff received by male and female patients and to determine the feasibility of using CT-Scan in the installation. The DE value for the head section is obtained by multiplying the DLP value by the conversion factor (k). The DE analysis in the head was carried out using the standard value of the Regulation of the Head of Bapeten No. Rek: LT/STI/KN 01/P2STPFRZR1/077/2016, while Deff is obtained from the CTDIVOL value multiplied by Wt. The results of the calculation of Deff received by male patients were 0.51 ± 0.01 mGy and female patients were 0.48 ± 0.01 mGy. The results of the DE calculation for male patients were 2.38 ± 0.08 mGy and female patients were 2.28 ± 0.08 mGy. The result of the head DE calculation according to BAPETEN guidelines is 2.94 mGy. Based on the results of the DE calculation on the head, the DE value is still within the normal limits issued by the BAPETEN guidelines so that the Siemens 128 Slice CT-Scan in the installation is still suitable for use for CT-Scan examination of the head.

Abstract

Research has been carried out on the potential for colon and urinery bladder cancer as a result of irradiating a 128 slice Siemens Somatom abdominal CT Scan at Sanglah Hospital, Denpasar. The data used in this study are secondary data from abdominal CT Scan medical records from January 2021 to June 2022, namely, CTDIvol and DLP adult patients who are female and male with an exposure factor of 110 kV X-ray tube voltage and current. Irradiation time starts from 600 mAs to 1200 mAs. This study aims to determine the potential risk of cancer  of the colon and urinery bladder from the results of the CT Scan examination brand Siemens Somatom 128 Slice and to compare the potential risks of colon and bladder cancer in men. and women. The magnitude of is done by calculating the estimated dose equivalent of yang diterima pasien dikalikan dengan faktor risiko kanker organ kritis pada pasien dewasa, sedangkan analisis komparatif dilakukan dengan menggunakan Independent Sample T Test. Hasil perhitungan rata-rata usus besar pada wanita dan pria masing-masing adalah 0,0044 ± 0,00062% dan 0,0045 ± 0,00079% sedangkan rata-rata  kandung kemih pada wanita dan pria masing-masing adalah -0,0034±0,00049% dan 0,0035±0,00061%. Terdapat perbedaan yang bermakna potensi kanker usus besar dan kandung kemih antara wanita dan pria dengan nilai P<0,050 pada usus besar dan kandung kemih yaitu masing-masing 0,026 dan 0,025. Perbedaan rata-rata kanker usus besar dan kandung kemih antara wanita dan pria adalah masing-masing 0,0001±0,00017% dan 0,0001±0,00012%, dimana potensi terjadinya kanker baru pada pasien pria lebih besar dibandingkan pasien wanita.
