15) that warrant retrospective corrections as proposed in [42], which, however, are not yet validated in clinical routine. 1 Description Standard MR-AC methods are based on the segmentation of three or four tissue classes (air, lung, and water or air, lung, fat, and water) from MR images that are acquired with dedicated sequences. However, segmentation may fail in routine application and cause inverted tissue classification. 16 shows a patient study where the tissue classes air and lung tissue (4-class segmentation) were inverted for a limited coaxial imaging range of the lower thorax, leading to incorrect attenuation correction of the PET activity in the thorax.

Further show that completing the truncated attenuation map with data extracted from non-attenuation-corrected (NAC) PET data globally reduced these biases to below 10 % [22]. The idea of using NAC-PET images to improve low-quality attenuation maps was already considered before the introduction of combined PET/CT systems and is based on the concurrent reconstruction of both, the PET emission activity distribution and the attenuation map [23]. The improvements from using extended field-of-view attenuation maps [23, 24] in PET/MR are illustrated in Fig.
