Technical Challenge for Integrated PET/MR systems: MR-based attenuation correction

T1 TSE + FDG PET

• Segmentation of n=4 tissue compartments using Dixon MR- sequences

μ-map for PET AC

•MR-artifacts will effect µ-map and quantitative PET values • Other techniques for MR-AC have been presented • Potential to use of segmented µ-map for RT planning?
