MR-Based PET attenuation correction for PET/MR imaging

Semin Nucl Med. 2013 Jan;43(1):45-59. doi: 10.1053/j.semnuclmed.2012.08.002.


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 scanners. New methods to compute attenuation maps from MR data have therefore been developed.
