A decade of PET/MRI clinical imaging has passed and many of the pitfalls are similar to
those on earlier studies. However, techniques to overcome them have emerged and …

Introduction Positron emission tomography (PET) is a fully quantitative technology for
imaging metabolic pathways and dynamic processes in vivo. Attenuation correction of raw …

Whole-body PET/MR hybrid imaging combines excellent soft tissue contrast and various
functional imaging parameters provided by MR with high sensitivity and quantification of …

Present attenuation-correction algorithms in whole-body PET/MRI do not consider variations
in lung density, either within or between patients; this may adversely affect accurate …

This study was to obtain voxel-wise PET accuracy and precision using tissue-segmentation
for attenuation correction. We applied multiple thresholds to the CTs of 23 patients to classify …

Attenuation correction has been one of the main methodological challenges in the
integrated positron emission tomography and magnetic resonance imaging (PET/MRI) field …

Hybrid PET/MRI scanners have become commercially available in the past years but are not
yet widely distributed. The combination of a state-of-the-art PET with a state-of-the-art MRI …

Quantitative PET/MRI is dependent on reliable and reproducible MR-based attenuation
correction (MR-AC). In this study, we evaluated the quality of current vendor-provided …

Fully integrated PET/MR imaging holds great promise as a novel hybrid imaging modality in
oncology and might offer advantages to PET/CT in many instances, especially because of …

Multimodality imaging can be a powerful tool for the simultaneous evaluation of both
anatomic and functional information and may potentially improve patient management …
