Attenuation correction (AC) is a critical requirement for quantitative PET reconstruction.
Accounting for bone information in the attenuation map (μ map) is of paramount importance …

Abstract Background In PET/MRI, linear photon attenuation coefficients for attenuation
correction (AC) cannot be directly derived, and cortical bone is, so far, usually not …

Abstract Introduction The combination of Positron Emission Tomography (PET) with
magnetic resonance imaging (MRI) in hybrid PET/MRI scanners offers a number of …

Purpose Accurate attenuation correction (AC) is essential for quantitative analysis of PET
tracer distribution. In MR, the lack of cortical bone signal makes bone segmentation difficult …

Simultaneous PET/MR of the brain is a promising technology for characterizing patients with
suspected cognitive impairment or epilepsy. Unlike CT, however, MR signal intensities do …

One of the challenges in PET/MRI is the derivation of an attenuation map to correct the PET
image for attenuation. Different methods have been suggested for deriving the attenuation …

Attenuation correction (AC) with an ultrashort echo time (UTE) sequence has recently been
used in combination with segmentation for cortical bone identification for brain PET/MR …

Attenuation correction is a notable challenge associated with simultaneous PET/MRI,
particularly in neuroimaging, where sharp boundaries between air and bone volumes exist …

Abstract Aim Combined PET/MR systems have now become available for clinical use. Given
the lack of integrated standard transmission (TX) sources in these systems, attenuation and …

Background MRI does not offer a direct method to obtain attenuation correction maps as its
predecessors (stand-alone PET and PET/CT), and bone visualisation is particularly …
