Evaluation of a clinical PET/MR system

چکیده
Hybrid imaging devices combining Positron-Emission-Tomography (PET) with Magnetic-Resonance-Imaging (MRI) have been shown to possess a great potential for small animal studies. Recently PET/MR systems have also been built for human applications. Here we present an evaluation of the first hybrid PET/MR device, which has the capabilities to perform simultaneous PET/MR acquisitions of the human brain. The influence of the PET insert on the MR imaging performance was evaluated. Furthermore fundamental PET parameters were accessed with and without MR sequences running. In vivo PET/MR studies of patients have been performed, where the attenuation correction for the PET was based on MR data.

Preliminary evaluation of image quality in a new clinical ToF-PET/MR scanner.
GE Healthcare, Waukesha, USA A new ToF-PET/MR scanner has recently been deployed at the University Hospital of Zurich for clinical evaluation purposes. The goal of the present work was to compare the image quality obtained on this system with that of equivalent state-of-the-art standalone scanners. The GE Signa PET/MR is a whole-body scanner combining a 3T wide-bore MR system with a 25 cm PET d...

PURPOSE We aim to evaluate the utility/improved accuracy of hybrid PET/MR compared to current practice separate 3T MRI and PET-CT imaging for localization of seizure foci. METHOD In a pilot study, twenty-nine patients undergoing epilepsy surgery evaluation were imaged using PET/MR. This subject group had 29 previous clinical 3T MRI as well as 12 PET-CT studies. Prior clinical PET and MR image...

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-...
