One of the early promises of PET was that it would be quantitative (1), as opposed to imaging modalities such as x-ray CT, MRI, or SPECT, in which quantification is more of a challenge than in PET. By quantitative is meant that a raw PET signal can be transferred into absolute activity concentrations of the radiopharmaceutical in all tissues in units of, for example, kBq/cm3. In this sense, PET...
Background: Gallium-66 (T1/2= 9.49 h) is an interesting radionuclide that has potential for positron emission tomography (PET) imaging of biological processes in intermediate to slow target tissue uptake. Oxine has been labeled with this radioisotope in the form of [66Ga]gallium chloride for its possible diagnostic properties. Materials and methods: 66Ga was produced in the 30 MeV cyclotron (Cy...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
OBJECTIVE To determine whether combining isosulfan blue dye with a radiopharmaceutical agent will increase intraoperative detection of sentinel nodes (SNs) in patients with early-stage melanoma. PATIENTS AND DESIGN Clinical trial with a consecutive sample. Eighty-seven patients with clinical stage I melanoma underwent preoperative lymphoscintigraphy with 1 of 3 radiopharmaceutical agents to i...
18Fluoromethylcholine (18F-Choline, 18F-FCH) has been produced using a home-made automatic synthesiser at 30 MeV Cyclotron Centre, 108 Military Central Hospital. In order to be licensed for patients, the 18F-FCH radiopharmaceutical needs meet required quality specifications listed in pharmacopeia. The objective of this study was build up analytical procedure and perform control followed EuPh201...
