Evolution of CT radiation dose in pediatric patients undergoing hybrid 2-[ 18 F]FDG PET/CT between 2007 and 2021

| description | To evaluate the evolution of CT radiation dose in pediatric patients undergoing hybrid 2-[
F]fluoro-2-deoxy-D-glucose (2-[
F]FDG) PET/CT between 2007 and 2021.
Data from all pediatric patients aged 0-18 years who underwent hybrid 2-[
F]FDG PET/CT of the body between January 2007 and May 2021 were reviewed. Demographic and imaging parameters were collected. A board-certified radiologist reviewed all CT scans and measured image noise in the brain, liver, and adductor muscles.
294 scans from 167 children (72 females (43%); median age: 14 (IQR 10-15) years; BMI: median 17.5 (IQR 15-20.4) kg/m
) were included. CT dose index-volume (CTDIvol) and dose length product (DLP) both decreased significantly from 2007 to 2021 (both
< 0.001, Spearman's rho coefficients -0.46 and -0.35, respectively). Specifically, from 2007 to 2009 to 2019-2021 CTDIvol and DLP decreased from 2.94 (2.14-2.99) mGy and 309 (230-371) mGy*cm, respectively, to 0.855 (0.568-1.11) mGy and 108 (65.6-207) mGy*cm, respectively. From 2007 to 2021, image noise in the brain and liver remained constant (
= 0.26 and
= 0.06), while it decreased in the adductor muscles (
= 0.007). Peak tube voltage selection (in kilovolt, kV) of CT scans shifted from high kV imaging (140 or 120kVp) to low kV imaging (100 or 80kVp) (
< 0.001) from 2007 to 2021.
CT radiation dose in pediatric patients undergoing hybrid 2-[
F]FDG PET/CT has decreased in recent years equaling approximately one-third of the initial amount.
Over the past 15 years, CT radiation dose decreased considerably in pediatric patients undergoing hybrid imaging, while objective image quality may not have been compromised. |
