Purpose The combination of positron emission tomography (PET) and magnetic resonance
(MR) tomography in a single device is anticipated to be the next step following PET/CT for …

For attenuation correction (AC) in PET/MRI systems, segmentation-based methods are most
often used. However, the standardized uptake value (SUV) of lesions in the bone and liver …

PET/MRI is an emerging dual-modality imaging technology that requires new approaches to
PET attenuation correction (AC). We assessed 2 algorithms for whole-body MRI-based AC …

Attenuation correction (AC) of whole-body PET data in combined PET/MRI tomographs is
expected to be a technical challenge. In this study, a potential solution based on a …

In routine whole-body PET/MR hybrid imaging, attenuation correction (AC) is usually
performed by segmentation methods based on a Dixon MR sequence providing up to 4 …

Abstract Purpose In combined PET/MRI standard PET attenuation correction (AC) is based
on tissue segmentation following dedicated MR sequencing and, typically, bone tissue is not …

Purpose A critical question in the development of combined MR/PET scanners is whether
MR can provide the tissue attenuation data required for PET reconstruction. Unfortunately …

Abstract Objective Hybrid PET/MRI presents many advantages in comparison with its
counterpart PET/CT in terms of improved soft-tissue contrast, decrease in radiation …

Attenuation correction is an essential component of the long chain of data correction
techniques required to achieve the full potential of quantitative positron emission …

Purpose Integrated whole-body PET/MRI tomographs have become available. PET/MR
imaging has the potential to supplement, or even replace combined PET/CT imaging in …
