A Simple, Rapid and Efficient Preparation of 99mTc-Compounds by Electrolysis (I) 99mTc-Albumin, 99mTc-Millimicrosphere

Technique for the rapid preparation of lung scan particles using 99mTc-sulfur and human serum albumin.

Optimized preparation and evaluation of 99mTc-Streptomycin

Introduction: The endemic occurrence of new strains of tuberculosis around the globe has initiated new research on developing diagnostic radiopharmaceutical based on antibiotics. Methods:Tc-99m labeled streptomycin was prepared using freshly milked 99mTcO4- and various concentrations of streptomycin, stannous chloride at various temperatures in high yield radio...

Prognostic utility of 90Y radioembolization dosimetry based on fusion 99mTc-macroaggregated albumin-99mTc-sulfur colloid SPECT.

UNLABELLED Planning hepatic (90)Y radioembolization activity requires balancing toxicity with efficacy. We developed a dual-tracer SPECT fusion imaging protocol that merges data on radioactivity distribution with physiologic liver mapping. METHODS Twenty-five patients with colorectal carcinoma and bilobar liver metastases received whole-liver radioembolization with resin microspheres prescrib...

99mTc-N-DBODC5, a new myocardial perfusion imaging agent with rapid liver clearance: comparison with 99mTc-sestamibi and 99mTc-tetrofosmin in rats.

UNLABELLED (99m)Tc-[bis (dimethoxypropylphosphinoethyl)-ethoxyethylamine (PNP5)]-[bis (N-ethoxyethyl)-dithiocarbamato (DBODC)] nitride (N-PNP5-DBODC or N-DBODC5) is a new monocationic myocardial perfusion tracer. We sought to compare the myocardial uptake and clearance kinetics and organ biodistribution of (99m)Tc-N-DBODC5 with (99m)Tc-sestamibi and (99m)Tc-tetrofosmin. METHODS Seventy-five a...

99mTc-Tetrofosmin in Rats

99mTc-[bis (dimethoxypropylphosphinoethyl)-ethoxyethylamine (PNP5)]-[bis (N-ethoxyethyl)-dithiocarbamato (DBODC)] nitride (N-PNP5-DBODC or N-DBODC5) is a new monocationic myocardial perfusion tracer. We sought to compare the myocardial uptake and clearance kinetics and organ biodistribution of 99mTc-N-DBODC5 with 99mTc-sestamibi and 99mTc-tetrofosmin. Methods: Seventy-five anesthetized Sprague–...
