The purpose of this study was to assess the consistency of T1ρ measurements across multiple acquisition platforms in a phantom study. The phantom consisted of five gels of varying agarose concentration yielding T1ρ relaxation times similar to cartilage. T1ρ measurements were compared from four combinations of scanner and coil, yielding consistent measurements across all platforms and demonstrating the usefulness of the phantom as a validation and quality assurance tool.
