[A Novel Support Material for MRI Phantom Study].

Purpose: For MRI phantom experiments, when a support such as agar is used to fix a container holding a substance to be measured, difficulties arise, such as the time and effort for support preparation and material changes occurring over time. We specifically examined super absorbent polymer (SAP) and confirmed the usefulness of SAP as a new support for MRI phantoms in terms of measurement and changes over time.
Methods: The simplicity of preparing SAP as a support, its influence on the measured values of substances, and its changes over time were compared with those of agar.
Results: Compared to agar, SAP was easier to prepare. The measured values, which were stable over time, were not markedly different from those of agar.
Conclusion: It was suggested that SAP could be useful as a new support in MRI phantom experiments in terms of measurements, procedures, techniques, and handling over time.
