Recent progress on imaging technology and performance testing of PET/MR

Purpose Integrated positron emission tomography and magnetic resonance (PET/MR) is a multimodality imaging technology integrating PET and MR, which can reflect the anatomical structure and physiological function simultaneously. With the development of this technology, PET/MR plays an increasingly important role in clinical diagnosis and treatment. This review would demonstrate the current state of the latest advancement of PET/MR detection technology.
Methods In this review, some studies of PET/MR detection technology in motion artifact correction, time of flight, noise reduction, performance testing methods, and phantoms were summarized.
Results and conclusions PET/MR is advancing rapidly in imaging technology and has achieved phasedachievements. The performance testing results of different models prove that the integration of PET and MR does not affect the respective performance, and the performance testing phantom for PET/MR needs further development.
