Estimation of Effective Dose to Patients Who Undergone Whole Body 18F-FDG PET-CT Examinations in North Palestine رسالة ماجستير

Abstract

This study aimed to assess the total effective dose of patients who have undergone a Positron Emission Tomography (PET-CT) scan using 18F-FDG radiopharmaceutical. The sample of the study (N = 150) consisted of patients with a mean age of 51.0 ± 16.3 years old, there were slightly more male (52.0%) than female (48.0%) patients. The IDAC-Dose 2.1 program was used to measure effective doses from 18F-FDG radiopharmaceutical, which is developed by the International Commission on Radiological Protection (ICRP). Virtual Dose™ CT, a web-based Computed Tomography CT dose calculator developed by the National Cancer institute , used for external dose estimations. The mean CT effective dose was 22.61 ± 4.23 millisievert (mSv), ranging from 13.0 to 34.4 mSv, while the mean F-18 effective dose was 3.51 ± 1.28 mSv, ranging from 1.79 to 11.90 mSv, giving a mean total effective dose of 26.12 ± 4.55 mSv, ranging from 15.39 to 37.47 mSv
