373 Objectives In 2010, a hybrid whole body PET/MR system (Philips Ingenuity TF PET/MR)
was installed at our institute. PET/MR is expected to offer many new possibilities in the field …

Purpose/Introduction: Sequential PET/MR scanners for whole body investigations have
been developed only recently and are starting to become commercially available. In 2011 …

1469 Objectives: The success of whole-body (WB) PET/CT has led to an increased interest
also in combined PET/MR as a complementary hardware combination. However, neither …

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 …

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 …

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 …

MR-based PET attenuation correction using segmented MR images is a promising approach
to compensating for the lack of a transmission source in PET/MR and solving the problem of …

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 …

260 Objectives: To perform scatter and attenuation correction in future whole-body MR/PET
devices, it is necessary to determine an attenuation map with the attenuating factors for 511 …
