OBJECTIVES To compare the ability of (99m)Tc-labeled broad-based matrix metalloproteinase inhibitor (RP805) (MPI) and (99m)Tc-annexin V to identify more advanced atherosclerotic disease in apolipoprotein E-null (apoE(-/-)) mice. BACKGROUND Both MMP expression and apoptotic cell death occur in both early and in advanced atherosclerotic plaques. METHODS(More)
The results of studies conducted with a small field of view tomographic gamma camera based on a Position Sensitive Photomultiplier Tube are reported. The system has been used for the evaluation of radiopharmaceuticals in small animals. Phantom studies have shown a spatial resolution of 2mm in planar and 2-3mm in tomographic imaging. Imaging studies in mice(More)
BACKGROUND Receptor for advanced glycation endproducts (RAGE) expression contributes to the impaired angiogenic response to limb ischemia in diabetes. The aim of this study was to detect the effect of increased expression of RAGE on the angiogenic response to limb ischemia in diabetes by targeting αvβ3 integrin with 99mTc-labeled Arg-Gly-Asp (RGD).

We report on studies of a small field of view scintimammography camera based on a position sensitive PMT and a crystal scintillator array. A 5-inch R3292 Hamamatsu PMT was coupled to a variety of scintillators, including pixelized NaI(TI), Csi (Na) and YAP. Laboratory and phantom studies were performed to compare performances of the above scintillator(More)
