Creating a 3D-printed pelvic phantom to explore the impact of Magnetic Resonance (MR) scanner noise in radiomics analysis, a technical note.

Reproducibility of radiomics features necessitates that scanner noise be considered prior to feature extraction. Phantom research provides the opportunity for such ‘ground truth’ measurements, without the additional complication of patient-related factors. The aim of this technical note was to create a 3D printed Magnetic Resonance Imaging (MRI)-compatible pelvic phantom that can be used for subsequent analysis of the impact of scanner noise on the reproducibility of radiomics features.
