SPECT low-field MRI system for small-animal imaging.
UNLABELLED Localization of regions with increased uptake of radiotracer in small-animal SPECT is greatly facilitated when using coregistration with anatomic images of the same animal. As MRI has several advantages compared with CT (soft-tissue contrast and lack of ionizing radiation) we developed a SPECT/low-field MRI hybrid device for small-animal imaging. METHODS A small-animal single-pinho...
متن کاملUltra-high-resolution small- animal SPECT imaging
Today the majority of clinical molecular imaging procedures are carried out with single photon emitters and gamma cameras, in planar mode and Single Photon Emission Computed Tomography (SPECT) mode. Thanks to the development of advanced multi-pinhole collimation technologies, SPECT imaging of small experimental animals is rapidly gaining in popularity. Whereas resolutions in routine clinical SP...
متن کاملSystem Calibration and Image Reconstruction for a New Small-Animal SPECT System
A novel small-animal SPECT imager, FastSPECT II, was recently developed at the Center for Gamma-Ray Imaging. FastSPECT II consists of two rings of eight modular scintillation cameras and list-mode data-acquisition electronics that enable stationary and dynamic imaging studies. The instrument is equipped with exchangeable aperture assemblies and adjustable camera positions for selections of magn...
متن کاملEvaluation of the performance of parallel-hole collimator for high resolution small animal SPECT: A Monte Carlo study
Introduction: Image quality and accuracy of in vivo activity quantification in SPECT are affected by collimator penetration and scatter components, especially in high energy imaging. These phenomena highly depend on the collimator characteristic and photon energy. The presence of penetrated and scattered photons from collimator in SPECT images degrades spatial resolution, contr...
متن کاملThe application of a compact MR - compatible SPECT system for small animal SPECT / MR imaging and tracer kinetics studies
BODY: Objectives : A new F-18 agent for PET myocardial perfusion imaging (BMS747158) has been shown to have excellent image quality in a Phase I clinical trial. In a subgroup of patients undergoing imaging with this agent in a Phase II clinical trial, we assessed if dual gated perfusion study is feasible and leads to improved image quality. We generated motion free perfusion images by combining...
