Development of 111In-labeled porphyrins for SPECT imaging
Objectives: The aim of this research was the development of 111In-labeled porphyrins as possible radiopharmaceuticals for the imaging of tumors. Methods: Ligands, 5, 10, 15, 20-tetrakis (3, 5-dihydroxyphenyl) porphyrin) (TDHPP), 5, 10, 15, 20-tetrakis (4-hydroxyphenyl) porphyrin (THPP) and 5, 10, 15, 20-tetrakis (3,4-dimethoxyphenyl) porphyrin) (TDMPP) were labeled with 111InCl3 (produced from ...
متن کاملPerformance Evaluation of FBP Reconstruction in SPECT Imaging
Introduction: The purpose of this study is to define the optimal parameters for the tomographic reconstruction procedure in a routine single photon emission tomography. The Hoffman brain phantom is modified to evaluate the reconstruction method. The phantom was imaged in a 3 and 2-dimensional conformation and the results were compared. Materials and Methods: The 2D phant...
متن کاملNeuroreceptor SPECT Imaging Ligands
Neuroreceptor imaging is a promising area of brain imaging used to investigate various neurodegenerative and neuropsychiatric disorders. In the research setting, radiopharmaceuticals targeted to specific areas of the brain are used along with SPECT to assess and analyze functional mechanisms within brain structures. Utilization of the data that are collected from these studies may aid in the de...
متن کاملSPECT/CT imaging of bone
The skeleton is a metabolically active organ that undergoes continuous remodelling throughout life. Normal healthy bones are dynamic structures with inherent basal levels of turnover sustained by balanced osteoblastic and osteoclastic activity. Increased bone turnover (ie osteoblastic activity) is the central mechanism of attempts at bone healing in case of any insult, whether it is benign or m...
متن کاملFilter selection for 99mTc-Sestamibi myocardial perfusion SPECT imaging [Persian]
Myocardial perfusion SPECT imaging with Tc99m-sestamibi is the most accurate non-invasive means of detecting coronary artery disease and assessing the severity of perfusion abnormalities in the patients with coronary stenosis. Though simple and straight forward the results produced by the technique is very much affected by the details being used. One of the main problems with the test, wh...
