Ultra-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 کاملEvaluating the Recovery Process of Renal Ischemia/Reperfusion Injury in Rats Using Small-Animal SPECT
Background: Renal injuries associated with ischemia/reperfusion are a prevalent clinical phenomenon that can cause the emergence of progressive kidney diseases, eventually leading to chronic kidney injuries. The present study was conducted to evaluate the results obtained from non-invasive imaging using small-animal SPECT and investigate the recovery process in an animal model of renal ischemia...
متن کاملAdvanced brain dopamine transporter imaging in mice using small-animal SPECT/CT
UNLABELLED BACKGROUND Iodine-123-β-CIT, a single-photon emission computed tomography (SPECT) ligand for dopamine transporters (DATs), has been used for in vivo studies in humans, monkeys, and rats but has not yet been used extensively in mice. To validate the imaging and analysis methods for preclinical DAT imaging, wild-type healthy mice were scanned using 123I-β-CIT. METHODS The pharmaco...
