A quality control phantom was developed through a simple and easy protocol for T1, T2 and Fat fraction mapping. The phantom is constituted of 8 tubes containing Gd-DOTA or commercially available animal fat, each at various concentrations and stabilized in agarose gels. A 3D printed bubble trap was placed on top of the gels to limit the contrast agent dilution over time. The solutions are stable for at least 6 months and the manufacturing protocol is highly reproducible.
