Background:Ionizing radiation is the base of radiological modalities. TAE is an interventional radiology procedure in which patient is exposed to a lot of ionizing radiation, this study is designed to find out the dose given to the patient during the procedure.
Aim:To asses dose during the procedure of transarterial embolization (TAE) in patients of hepatocellular carcinoma (HCC).
METHODS: A cross-sectional retrospective study was performed at Rehman Medical Institute, Radiology Department, Peshawar from June 2020 to September 2020. Total number of 136 procedures of TAE was done during this time period on Artist zee imaging system from Siemens. The fluoroscopy time, number of exposures and total dose for each procedure was recorded and maintained in a register along with patient’s details including age, gender, weight and BMI. The doses are maintained to obtain a data of doses of all patients. Those patients in which doses are relatively high were assessed retrospectively to take steps in future to maintain low radiation doses of patients for TAE.
Results: The average fluoroscopy time is 18.2 minutes with average total exposures of 9 and total dose of 12393 mGym3. This data will help in taking steps for reduction of doses in patients undergoing TAE procedure.
Conclusion: With the increasing use of TAE as a treatment for HCC, it is important to employ exposure-reducing methods to complete the procedure safely and at the lowest achievable dose. Even considering the given relative safety of this procedure as currently performed , operates need to be aware of the technique that can be employed to minimize those risks, This study has outlined those steps that can b taken to enhance the margin of safety for avoiding radiation injury without compromising the success of the procedure.
