Image Distortions in Clinical PET/MR Imaging

  • Chapter
  • First Online:
PET/MRI

Abstract

Whole-body PET/MR imaging has the potential to supplement or even replace combined PET/CT imaging in selected clinical indications. In view of the lack of separate standard transmission sources in combined PET/MR imaging systems, attenuation correction (AC) of the PET data is performed using the available MR images. Given the novelty of MR-based AC (MR-AC), related image distortions and subsequent methodological pitfalls need to be recognized. Here, we review the most common artifacts observed in routine PET/MR imaging following MR-AC in either sequential or fully integrated system designs.
