چکیده
We have developed a prototype PET detector which is compatible with a clinical MRI system to provide simultaneous PET and MR imaging. This single-slice PET system consists of 48 2 x 2 x 10 mm3 LSO crystals in a 38 mm diameter ring configuration that can be placed inside the receiver coil of the MRI system, coupled to three multi-channel photomultipliers housed outside the main magnetic field via 4 m long and 2 mm diameter optical fibres. The PET system exhibits 2 mm spatial resolution, 41% energy resolution at 511 keV and 20 ns timing resolution. Simultaneous PET and MR phantom images were successfully acquired.

Recent Advances in PET-MR Hybrid contrast agent
Introduction: All of the Imaging modalities have advantages and disadvantages alone. So if we want to have the best and perfect image, combining these modalities produces something we desired. PET-MR images consist of morphologic and metabolic data. MRI and PET provide high spatial and contrast resolution and high sensitivity and molecular information respectively. Hybrid PET-...
متن کاملSimultaneous MR/PET imaging of the human brain: feasibility study.
The purpose of this study was to apply a magnetic resonance (MR) imaging-compatible positron emission tomographic (PET) detector technology for simultaneous MR/PET imaging of the human brain and skull base. The PET detector ring consists of lutetium oxyorthosilicate (LSO) scintillation crystals in combination with avalanche photodiodes (APDs) mounted in a clinical 3-T MR imager with use of the ...
متن کاملTechnical Challenges & Opportunities of PET/MR: An Overview
Following PET/CT, PET/MR is the newest diagnostic whole-body hybrid imaging modality. Simultaneous PET and MR data acquisition requires novel technical solutions and offers new diagnostic opportunities. Attenuation correction (AC) and motion correction (MC) of PET data are current hot topics in PET/MR hybrid imaging research. The added diagnostic value of PET/MR in whole-body imaging is current...
متن کاملMR-Based PET Motion Correction Procedure for Simultaneous MR-PET Neuroimaging of Human Brain
Positron Emission Tomography (PET) images are prone to motion artefacts due to the long acquisition time of PET measurements. Recently, simultaneous magnetic resonance imaging (MRI) and PET have become available in the first generation of Hybrid MR-PET scanners. In this work, the elimination of artefacts due to head motion in PET neuroimages is achieved by a new approach utilising MR-based moti...
متن کاملSystematic evaluation of phantom fluids for simultaneous PET/MR hybrid imaging.
UNLABELLED With the recent advent of integrated PET/MR hybrid systems, the need for simultaneous PET and MR phantom measurements arises. Phantom fluids that are used in stand-alone MR systems, especially in larger phantoms and at a high magnetic field strength, are not necessarily applicable in PET imaging and vice versa. In this study, different approaches to fluid selection were considered an...
