A body phantom, containing a prostate mimic with traceable T1/T2/ADC standards, was designed and manufactured to assess acquisition-, system-, and RF coil- dependent variances of quantitative MRI parameters. In order to explore the potential of the phantom as a quality assurance tool, two phantoms were constructed and evaluated with two receive coil configurations across two scanners over a period of three weeks. It is demonstrated that this phantom is a useful prostate specific quality assurance tool and provide the information needed to harmonize results thus minimizing the impact of multiple dependencies on quantitative results.
