172 Background: PET/MR imaging offers promising opportunities for multi-parametric
imaging that yields perfectly registered anatomical, functional and molecular information …

Hybrid PET/MR imaging is emerging as a new diagnostic tool in clinical practice with the
major vendors providing hybrid scanners that are now certified for clinical use. This new …

Philips has introduced the world's first whole body sequential PET/MR system. We present
the current status of MR-based attenuation correction (MRAC) technique. MRAC consists of …

Attenuation correction (AC) is one of the most important corrections that need to be
performed in PET imaging (Fig. 1). AC methods aim to account for the photon attenuation …

First prototype clinical PET/MRI scanners are readily available to be tested in patient studies.
In addition to provide a unique possibility for multifunctional imaging with temporally and …

Objectives The aim of this study was to develop a method for tracking respiratory motion
throughout full MR or PET/MR studies that requires only minimal additional hardware and no …

1157 Objectives: 1. Comparison between PET/CT and PET/MRI in detecting distant
metastases of lung cancer 2. Review of the potential advantages of PET/MRI compared with …

Quiescent period gating of PET data reduces respiratory motion artifacts in PET imaging.
However, a respiratory phase mismatch between attenuation map and gated PET data …

2108 Objectives In order to compensate for the degradation of PET image quality due to
respiration, accurate tracking of respiratory motion is required. This is achieved by means of …

Simultaneous PET and MR imaging offers unprecedented opportunities to synergize the
physiologic and molecular imaging capability of PET and the excellent anatomic and …
