Introduction: Due to the cell labeling potentials of various metal-maltol complexes, the idea of developing a possible cell labeling imaging agent using single photon emission computed chromatography (SPECT) with[111In]-maltolate complex has been investigated. Methods: [111In] labeled 3-hydroxy-2-methyl-4H-pyran-4-onate ([111In]-maltolate) was prepared using f...

We investigate the optoelectronic properties of single indium arsenide nanowires, which are grown vertically on p-doped silicon substrates. We apply a scanning photocurrent microscopy to study the optoelectronic properties of the single heterojunctions. The measured photocurrent characteristics are consistent with an excess charge carrier transport through midgap trap states, which form at the ...

Introduction: In nuclear medicine imaging, detection of the scattered photons along with the primary photons is one of the major problems that can lead to a decrease in ddiagnostic accuracy. Therefore, use of a suitable scatter correction method can help to improve of the image quality and increase of diagnostic accuracy. The aim of this study is evaluation of five energy wind...

Introduction: The aim of this study was to evaluate the human organ absorbed dose of [111In]In-DTPA-antiMUC1, as a newly developed radioimmunoconjugate. Methods: [111In]In-DTPA-antiMUC1 was prepared at optimized conditions while the radiochemical purity of the tracer was investigated using ITLC method. Biodistribution of the radiolab...

The somatostatin analogue octreotide may be used in the diagnosis of carcinoid and other neuroendocrine tumours. Radionuclide scanning following intravenous injection of 111Indium-labelled octreotide (111In-DTPA-pentetreotide) provides a sensitive, non-invasive method of localising somatostatin-positive tumours. The technique may also be used to identify patients who may respond to 'cold' octre...

In this study, the preparation of 111In-Bleomycin complex was optimized for temperature, time, concentration and pH during several experiments. The results showed that by the addition of bleomycin to 111In-InCl3 sample (dried under flow of N2) and heating the mixture up to 90-100°C the radiopharmaceutical can be obtained in 99.5% yield and a specific activity of 1.745 Ci/mmol. The final s...

Studies in the collagen and rabbit models of arthritis have indicated that indium-111 chloride (111InCl3) scintigraphy objectively measures synovial inflammation. Indium-111 chloride scans, with imaging three days after 19 MBq intravenous injection, were performed on 21 patients with definite or classical rheumatoid arthritis (RA), all of whom were functional class II. Standard clinical indices...
