Evaluation of precalculated attenuation correction map for preclinical cardiac PET/MR using a 1H/23Na surface coil

Abstract Background In preclinical PET/MR, attenuation correction (AC) uses a mix of pre-calculated attenuation maps accounting for animal cradles and organ segmentation obtained from whole-body MR using a volume coil. The development of X-nuclei such as 23Na or 31P may benefit from high sensitivity...
