Direct labeling of macroaggregated albumin with indium-111-chloride using acetate buffer.

کاربرد میکرو ذرات چیتوزان – تکنسیوم-99 در تصویربرداری ریه موش: یک گزارش کوتاه

Background and Objective: In nuclear medicine, lung perfusion scintigraphy is performed by radiolabeled particles, 99 mTc-albumin macroaggregated. Synthesizing of the particles has some difficulties. In order to resolve this problem, chitosan microparticles were used as an alternative choice.  Materials and Methods: The qualitative control tests including: the determining particles size...

Indium-111 maltolate complex as a cell labeling agent for SPECT imaging

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...

Direct Carbon-Carbon Bond Formation from Alcohols and Active Methylenes, Alkoxyketone, or Indoles Catalyzed by Indium Trichloride without Salt Formation

Preclinical evaluation of 68Ga-MAA from commercial available 99mTc-MAA kit

99mTc-Macroaggregated Albumin (99mTc-MAA) has been used as a perfusion agent. This study described development of the 68Ga-MAA via commercially available kits from Pars-Isotopes Company as a 99mTc-MAA kit. 68Ge/68Ga generator was eluted with suprapure HCl (0.6 M, 6 mL) in 0.5 mL fractions. The two fractions with the highest 68GaCl3 activity were generally used for labeling purposes. After label...

Nuclide imaging of vascular graft-platelet interactions: comparison of indium excess and technetium subtraction techniques.

Indium-111-labeled platelet adherence to ePTFE thoracoabdominal vascular prostheses in a canine model (n = 10) was quantitated by (1) an indium-111 excess technique, contrasting graft radioactivity to that in a reference region, and (2) a technetium-99m subtraction technique, with radioactivity of circulating platelets eliminated by discounting background blood activity. Variation in graft thro...
