Synopsis

Keywords: PET/MR, PreclinicalWe developed a retrofitted alignment apparatus that attaches to the MRI’s motor-driven automated positioning system and enables simultaneous preclinical PET/MRI at 9.4T with a stand-alone microPET ring. The system leverages 3D printing technology to achieve stable alignment between the two modalities, consistent placement of animals, and rapid reconfiguration between PET-MRI and MRI-only experiments. Thereby addressing the shortcomings of other retrofitted designs and proving simultaneous PET-MRI capabilities at a reduced cost.
