Fetal dose in pregnant CT patients: a comparison of four software packages.

ABSTRACT:

Objectives

To compare the fetal dose (FD) as calculated by four different software packages for pregnant women who have undergone CT acquisitions directly exposing the whole fetus to X-rays.

Materials and methods

Pregnant women who underwent CT abdomen-pelvis and/or thorax-abdomen-pelvis acquisitions from February 2018 to May 2024 and for whom the uterine dose and/or FD was calculated by a medical physicist were retrospectively included. FDs were computed per CT acquisition with VirtualDose-CT™ (VDCT), Duke Organ Dose (DOD), fetaldose.org, and COnceptus Dose Estimation (CODE) software, using phantoms taking the stage of pregnancy into account. FDs calculated by each software package were then compared.

Results

A total of 51 pregnant women with a mean age of 30.2 ± 5.7
