摘要

Hybrid MR–PET data acquisition in simultaneous mode confers a number of advantages at 3T and 9.4T. From an MR perspective, the potential for ultra-high resolution structural imaging is discussed and example images of the cerebellum with an isotropic resolution of 320μm are presented. Further, metabolic imaging is discussed and high-resolution images of the sodium distribution are demonstrated. Examples of tumour imaging on a 3T MR–PET system are included and discussed.
