Comparison of quantitative [11C]PE2I brain PET studies between an integrated PET/MR and a stand-alone PET system

Hybrid positron emission tomography/magnetic resonance (PET/MR) systems have opened up many new neuroimaging opportunities, potentially providing a great tool for a broad range of research and clinical applications in neurology [1,2]. Initially, clinical neuroimaging applications for PET/MR have been hampered partially due to the lack of a widely accepted subject-specific attenuation correction (AC) method for the PET data [3]. The main reason is that MRI provides no direct information on electron density that can be used for photon AC [4,5].
