Automated Measurement of Effective Radiation Dose by ¹⁸F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography.

ABSTRACT:

Background/objectives

Calculating the radiation dose from CT in ¹⁸F-PET/CT examinations poses a significant challenge. The objective of this study is to develop a deep learning-based automated program that standardizes the measurement of radiation doses.

Methods

The torso CT was segmented into six distinct regions using TotalSegmentator. An automated program was employed to extract the necessary information and calculate the effective dose (ED) of PET/CT. The accuracy of our automated program was verified by comparing the EDs calculated by the program with those determined by a nuclear medicine physician (n = 30). Additionally, we compared the EDs obtained from an older PET/CT scanner with those from a newer PET/CT scanner (n = 42).
