MR-Based PET attenuation correction for PET/MR imaging

Ilja Bezrukov et al. Semin Nucl Med. 2013 Jan.

Abstract

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.
