Technetium-99m Ceftizoxime Kit Preparation
The aim of this work was to prepare a kit of Tc-ceftizoxime (Tc-CFT), with stability and biological activity preserved, able to identify a septic focus (E. coli) in the experimental infection model in rats. The preparation of the CFT kit involved the use of lyophilized solutions containing the antibiotic ceftizoxime and the sodium dithionite reducing agent (6.0 mg/mL). After lyophilization, the...
متن کاملMicrowave Preparation of Technetium-99m Sulfur Colloid
Technetium-99m sulfur colloid ( mTc-SC) has been useful in reticuloendothelial imaging, and in particular in liver/spleen and more recently bone marrow scintigraphy. Technetium99m SC can also be employed to localize acute gastrointestinal bleeding and has been used in lung ventilation studies. The standard radiolabeling method requires a heating period in a boiling water bath. A comparison of a...
متن کاملDose from syringe procedures during technetium-99m radiopharmaceutical preparation.
UNLABELLED We examined the dose from 99mTc contained in syringes and shielded vials to assess in detail the dose burdens in a central pharmacy. METHODS Absorbed-dose rates at the end of the plunger of a shielded syringe, when 99mTc is contained either in the syringe or in a shielded vial from which the activity would be drawn, were measured with CaF2 dosimeters. The dose rates also were calcu...
متن کاملTechnetium-99m radiopharmaceutical preparation problems: 12 years of experience.
OBJECTIVE Chemical reactions involved in preparing 99mTc radiopharmaceuticals occasionally result in products of substandard purity. A retrospective examination of preparation problems that occurred in the author's institution was conducted to better define the incidence, recognize patterns and identify causes of substandard 99mTc radiopharmaceutical products. METHODS All 99mTc radiopharmaceu...
متن کاملDRAXIMAGE M A A Kit for the Preparation of Technetium Tc 99m Albumin Aggregated Injection DIAGNOSTIC - For Intravenous Use
The albumin human was non-reactive when tested for Hepatitis B Surface Antigen (HBsAg), antibodies to Human Immunodeficiency Virus (HIV-1/HIV-2), antibody to Hepatitis C Virus (anti-HCV) and Antigen to Human Immunodeficiency Virus (HIV-1). The aggregated particles are formed by denaturation of albumin human in a heating and aggregation process. Each vial contains 4 to 8 million particles. By li...
