This paper introduces three novel methods to evaluate attitude and position from vector observations using a vision-based technology camera. The first approach, called Linear Algebra Resection Approach (LARA), solves for attitude and position simultaneously and can be used in the lost-in-space case, when no approximate solution is available. The solution is shown to be the left eigenvector asso...

UNLABELLED The purpose of this study was to evaluate biodistributions and absorbed doses of anti-carcinoembryonic antigen (CEA)/anti-diethylenetriamine pentaacetic acid (DTPA)-indium (anti-DTPA-In) bispecific monoclonal antibody (BsMAb) F6-734 and 125I-labeled DTPA-indium dimer hapten (125I-di-DTPA-In hapten) in athymic mice xenografted with human medullary thyroid cancer. METHODS Bispecific ...

• Extracellular agents (such as Gd-DTPA) accumulate in the interstitium of many tissues (e.g. muscle) but do not cross the normal blood-brain-barrier. • Functional information may be obtained by treating Gd-DTPA as a tracer and following its kinetics (as opposed to the conventional ‘static’ approach, inject wait – image once). • After intravenous administration (normally in the form of a bolus)...

Purpose: Gd-EOB-DTPA is a liver-specific MR imaging contrast agent that is taken up by hepatocytes and excreted into the biliary system. MR cholangiography can be obtained by means of three-dimensional T1-weighted imaging at the optimal scan delay after the injection of Gd-EOB-DTPA (1). The aim of the present study was to evaluate the biliary enhancement dynamics of Gd-EOB-DTPA at MR cholangiog...

Cell tracking using iron oxide nanoparticles has been well established in MRI. However, in experimental rat models, the intrinsic iron signal derived from erythrocytes masks the labeled cells. The research evaluated a clinically applied Gd-DTPA for T1-weighted positive enhancement for cell tracking in spinal cord injury (SCI) rat models. MSCs were labeled with jetPEI/Gd-DTPA particles to evalua...

Mechanisms of increased epithelial lung clearance of DTPA in diffuse fibrosing alveolitis. S. Labrune, Th. Chinet, M.A. Collignon, L. Barritault, G.J. Huchon. ERS Journals Ltd 1994. ABSTRACT: The aim of this study was to elucidate possible mechanisms of increased epithelial lung clearance in diffuse fibrosing alveolitis (DFA). We investigated the relationships between epithelial lung clearance...

Accurate diagnosis in early stage is vital for the treatment of Hepatocellular carcinoma. The aim of this study was to investigate the potential of poly lactic acid-polyethylene glycol/gadolinium-diethylenetriamine-pentaacetic acid (PLA-PEG/Gd-DTPA) nanocomplexes using as biocompatible molecular magnetic resonance imaging (MRI) contrast agent. The PLA-PEG/Gd-DTPA nanocomplexes were obtained usi...
