Following investigation of a large number of new ligands based upon propylene amine oxime (PnAO) the d,l-diastereoisomer of hexamethyl propyleneamine oxime (HM-PAO) was selected as the preferred ligand for 99mTc as a tracer for cerebral perfusion imaging. The neutral, lipophilic 99mTc complex of d,l-HM-PAO was formed in high yield by stannous reduction of(More)
Soluble and insoluble polysaccharides were derivatized with diethylenetriaminepentaacetic acid (DTPA) and/or spin-labeled with 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO). Polysaccharides derivatized with DTPA were prepared via cyanogen bromide activation, coupling to a diamine linker, and to DTPA anhydride. Spin-labeled polysaccharides were also prepared(More)
The need for evaluation of community psychogeriatric programs is stressed. The results of the evaluation of an outpatient service, with a liaison component, based in a community general hospital are presented. The use of treatment outcome scales, user satisfaction surveys, and a study of cost effectiveness are discussed. The issues of needs assessment,(More)
A unique approach is developed for evaluating personnel requirements of the National Imagery and Mapping Agency (NIMA). With this approach new ways of measuring personnel availability are proposed and available to ensure that NIMA remains ready to provide timely, relevant, and accurate imagery, imagery intelligence and geospatial information in support of(More)
Magnetite (Fe3O4) particles 0.1-0.5 microns in diameter doped with either 99mTc or 111In have been prepared and characterized by electron microscopy and Mössbauer spectroscopy. The time courses of their distributions after injection into rats were determined, including studies by gamma-camera imaging; the main targets were the liver and lung. The(More)
