On the Accuracy and Reproducibility of a Novel Probabilistic Atlas-based Generation for Calculation of Head Attenuation Maps in Integrated PET/MR Scanners

摘要

PurposeTo propose an MR-based method for generating continuous-valued head attenuation maps and to assess its accuracy and reproducibility. Demonstrating that novel MR-based photon attenuation correction (AC) methods are both accurate and reproducible is essential prior to using them routinely in research and clinical studies on integrated PET/MR scanners.
