The 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...
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 کاملSPECT 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 کاملIntegrated 7T MRI and SPECT Systems for Small-Animal Imaging
Purpose MRI and single-photon emission computed tomography (SPECT) provide complimentary information which could aid in the diagnosis of various diseases. However, acquiring images from both modalities can been problematic. Until recently, SPECT systems could not be integrated with MRI systems due to the use of photomultiplier tubes which do not function in high magnetic fields. The development...
متن کاملA clinical gamma camera-based pinhole collimated system for high resolution small animal SPECT imaging.
The main objective of the present study was to upgrade a clinical gamma camera to obtain high resolution tomographic images of small animal organs. The system is based on a clinical gamma camera to which we have adapted a special-purpose pinhole collimator and a device for positioning and rotating the target based on a computer-controlled step motor. We developed a software tool to reconstruct ...
