Is Prone Position [<sup>18</sup>F]FDG PET/CT Useful in Reducing Respiratory Motion Artifacts in Evaluating Hepatic Lesions?
Prone position is useful in reducing respiratory motion artifacts in lung nodules on 2-Deoxy-2-[<sup>18</sup>F] fluoro-D-glucose ([<sup>18</sup>F]FDG) positron emission tomography/computed tomography (PET/CT). However, whether prone position PET/CT is useful in evaluating hep...

| description | Prone position is useful in reducing respiratory motion artifacts in lung nodules on 2-Deoxy-2-[<sup>18</sup>F] fluoro-D-glucose ([<sup>18</sup>F]FDG) positron emission tomography/computed tomography (PET/CT). However, whether prone position PET/CT is useful in evaluating hepatic lesions is unknown. Thirty-five hepatic lesions from 20 consecutive patients were evaluated. The maximum standardized uptake value (SUV<sub>max</sub>) and metabolic tumor volume (MTV) of both standard supine position PET/CT and additional prone position PET/CT were evaluated. No significant difference in SUV<sub>max</sub> (4.41 ± 2.0 vs. 4.23 ± 1.83; <i>p</i> = 0.240) and MTV (5.83 ± 6.69 vs. 5.95 ± 6.24; <i>p</i> = 0.672) was observed between supine position PET/CT and prone position PET/CT. However, SUV<sub>max</sub> changes in prone position PET/CT varied compared with those in supine position PET/CT (median, −4%; range: −30–71%). Prone position PET/CT was helpful when [<sup>18</sup>F]FDG uptake of the hepatic lesions was located outside the liver on supine position PET/CT (<i>n</i> = 4, SUV<sub>max</sub> change: median 15%; range: 7–71%) and there was more severe blurring on supine position PET/CT (<i>n</i> = 6, SUV<sub>max</sub> change: median 11%; range: −3–32%). Unlike in lung nodules, prone position PET/CT is not always useful in evaluating hepatic lesions, but it may be helpful in individual cases such as hepatic dome lesions. |
