Switching on the Lights for Real-Time Multimodality Tumor Neuroimaging: The Integrated Positron-Emission Tomography/MR Imaging System

An example of ¹¹C-methionine simultaneously acquired and superimposed on PET/MR imaging anatomic (A), proton MR spectroscopy (B), and diffusion tensor (C) imaging of a 42-year-old patient with an atypical neurocytoma on the left temporo-occipital lobe. Note the superior anatomic information provided by the spatial matching between MR images and PET images, the avid tracer uptake in the tumor, the spatial correlation with the spectroscopic findings, and the clear relationship to the adjacent optic radiation.
