Patient Radiation Doses by Body Interventional Radiology in Ubon Ratchathani Cancer Hospital

Abstract

         Body interventional radiology is a procedure that aims to provide treatment to a patient through the use of blood vessels, by inserting a small, specific medical device or a small particle substance into the patient's body for diagnosis and treatment, guided by an angiography. The procedure usually takes longer than a regular X-ray and results in the patient receiving higher radiation doses. Therefore, it is necessary to analyze the amount of radiation dose that the patient received from the radiological examination and treatment, and compare it with the reference radiation dose values, by collecting data from 96 patients who received radiotherapy of the body system during January and December 2022 at the Ubon Ratchathani Cancer Hospital, Ubon Ratchathani, Thailand. The study included three procedures of trans-arterial chemoembolization, intravascular embolization of abnormal blood vessels in the trunk, and insertion of a bile drainage tube through the skin. The average radiation doses received by the patients were found to be 68.26, 67.20, and 8.91 Gy/cm², respectively. By comparing with the standard reference radiation doses, Department of Medical Sciences, Ministry of Public Health, Thailand, 2023, and some international standards, it could be concluded that the cumulative radiation doses were found to be less than the reference dose limits.
