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

Purpose Recent studies have shown an excellent correlation between PET/MR and PET/CT
hybrid imaging in detecting lesions. However, a systematic underestimation of PET …

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 …

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 …

INTRODUCTION: In this study we proposed and developed a simple attenuation mapping
approach based on magnetic resonance imaging (MRI) for the purpose of reconstructing …

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 …

Purpose The objective of this study was to evaluate the performance of the built-in MR-
based attenuation correction (MRAC) included in the combined whole-body Ingenuity TF …

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 …

Hybrid PET/MR systems have recently entered clinical practice. Thus, the accuracy of MR-
based attenuation correction in simultaneously acquired data can now be investigated. We …
