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.

A 3D printed phantom of a male pelvis was created using fused deposition modelling technology. It was 3D printed using the high density MRI-compatible acrylonitrile butadiene styrene (ABS). The ‘negative’ mould created was then filled with silicone, and the prostate gland and femoral heads were also simulated.

We successfully created an MRI-compatible 3D printed pelvic phantom, with a test scan. The phantom will subsequently be utilised to determine the impact of MRI scanner noise on radiomics feature reproducibility.
