Standardization of imaging and automated adjustment of MR parameters could homogenize and expedite multiparametric MRI of the prostate. If automated and robust, spectroscopic imaging (MRSI) could be a part of this protocol. In this dual-centre study, an automated workflow was validated by patient measurements at 3T MR systems and the robustness of the spectroscopic imaging approach was evaluated. Automation of the acquisition protocol of multiparametric MR imaging of the prostate needed only minor manual adjustments. On average, 84% of the MRSI voxels within the prostate passed our quality control, illustrating the current robustness of the automated semi-LASER MRSI technique.
