Patient doses and cancer risks in fluoroscopy and interventional radiology procedures (original) (raw)

Interventional radiology was conceived early in 1964 as minimally invasive procedures and expanding ever since its success in improving patient outcomes, reducing in-hospital stays, and reducing morbidity and mortality of treatment in many organs and organ systems. Together with fluorosocopy, interventional radiology has many benefits and contributes to the collective radiation dose to the public. This study estimated the effective doses and fatal cancer risks incurred by patients from some selected fluorsocopy and interventional radiology procedures. The patient dose measurements were performed at the fluoroscopy and interventional radiology facilities in 9 hospitals in seven cities in Indonesia during the year of 2015 to 2019. A total of 38 procedures involving adult patients were used in this study. The procedures were grouped according to the UNSCEAR classification. The estimation was based on the reading of the cumulative dose (CD) and kerma-air product (KAP) displayed on the monitor screen of the X-ray machine multiplied by the readily available conversion coefficients. The effective dose values obtained were ranged from 1.684 to 6.2634 mSv, depending on the type of procedures, and resulted in the fatal cancer risk of 6.90×10-5 to 2.57×10-4 , or 1:14.483 to 1:3894. Comparison with other studies' measurement results suggests that both patient doses and fatal cancer risk in this study are somewhat reasonable among the various radiation medical applications.
