UNLABELLED PET/MRI is an emerging dual-modality imaging technology that requires new approaches to PET attenuation correction (AC). We assessed 2 algorithms for whole-body MRI-based AC (MRAC): a basic MR image segmentation algorithm and a method based on atlas registration and pattern recognition (AT&PR). METHODS Eleven patients each underwent a(More)
Recent progress has allowed hybrid positron emission tomography/magnetic resonance (PET/MR) systems to make the transition from research prototypes to systems with full potential for clinical imaging. Options for directly measuring the attenuation maps, as is possible with PET/computed tomography or PET transmission scans, are not included in PET/MR(More)
