A rapid high yield synthesis of no-carrier-added (-)-[123I]iodocyanopindolol
(Elsevier, 1991)
A convenient and efficient radiosynthesis of no-carrier-added [123I]labeled (-)iodocyanopindolol, (-)-[123I]ICYP, a high affinity [beta] adrenergic antagonist, is described. (-)-[123I]ICYP was synthesized by a modified ...
Multiphase extraction: Rapid phase-transfer of [18F]fluoride ion for nucleophilic radiolabeling reactions
(Elsevier, 1988)
In multiphase extraction [18F]fluoride ion for radiolabeling is recovered from target water by passage through a small column of microporous polymer impregnated with a lipophilic cryptand or quaternary ammonium salt. The ...
NMDA receptor channels: Labeling of MK-801 with iodine-125 and fluorine-18
(Elsevier, 1988)
Methods for labeling the glutamate channel blocking agent MK-801 with iodine-125 (125I) and fluorine-18 (18F) are described. Radioiodine was incorporated in the 1- or 3-positions of the aromatic ring of (+/-)MK-801 by ...
Potential tumor or organ-imaging agents, 24. Radioiodinated pregnenolone esters
(Elsevier, 1984-07)
A series of radioiodinated pregnenolone esters was prepared in an effort to find an agent that would be rapidly and selectively taken up by adrenal cortical tissue. Achievement of such a goal would provide the basis for ...
Diffusion imaging for evaluation of tumor therapies in preclinical animal models
(Springer-Verlag; ESMRMB, 2004-12)
The increasing development of novel targeted therapies for treating solid tumors has necessitated the development of technology to determine their efficacy in preclinical animal models. One such technology that can ...
A position sensitive [beta]-[gamma] coincidence technique for multiplexed gamma spectrometry of many small samples
(Elsevier, 1994-12-30)
A technique based on [beta]-[gamma] coincidence has been developed to perform multiplexed gamma-ray spectrometry of small samples using a single gamma-ray detector and a position sensitive beta detector. A system is described ...
Photoacoustic tomography of joints aided by an Etanercept-conjugated gold nanoparticle contrast agent-an ex vivo preliminary rat study
(2008)
"Monitoring of anti-rheumatic drug delivery in experimental models and in human diseases would undoubtedly be very helpful for both basic research and clinical management of inflammatory diseases. In this study, we have ...
Statistical performance evaluation and comparison of a Compton medical imaging system and a collimated Anger camera for higher energy photon imaging
(2008)
"In radionuclide treatment, tumor cells are primarily destroyed by charged particles emitted by the compound while associated higher energy photons are used to image the tumor in order to determine radiation dose and monitor ...
Retrospective correction of surface coil MR images using an automatic segmentation and modeling approach
(John Wiley & Sons, Ltd., 1997-05)
The use of surface coils in magnetic resonance imaging offers significant improvements in the signal-to-noise ratio over volume coils for many applications. However, the inhomogeneous reception profile of surface coils ...
