Tissues with low magnetic resonance (MR) signals, such as bones and lungs differ considerably in their attenuation properties, requiring special considerations for attenuation correction. We evaluated the impact of using the five-compartment segmentation model, which incorporates bones, in 68 Ga-PSMA-11 PET/MR studies in patients undergoing evaluation for prostate cancer.
