The diagnostic difference between 18F- FDG PET and 99mTc-HMPAO SPECT perfusion imaging in assessment of Alzheimer's disease
Introduction:Brain imaging with F-18 fluorodeoxyglucose (18F-FDG) positron emission tomography or Tc-99m hexamethylpropyleneamine oxime (99mTc-HMPAO) SPECT is widely used for the evaluation of Alzheimer's dementia (AD); we aim to assess superiority of one method over the other. Methods: Twenty four patients with clinical diagnosi...
متن کاملEvaluation of Simultaneous Dual-radioisotope SPECT Imaging Using 18F-fluorodeoxyglucose and 99mTc-tetrofosmin
Objective(s): Use of a positron emission tomography (PET)/single-photonemission computed tomography (SPECT) system facilitates the simultaneousacquisition of images with fluorine-18 fluorodeoxyglucose (18F-FDG) andtechnetium (99mTc)-tetrofosmin. However, 18F has a short half-life, and 511keV Compton-scattered photons are detected in the 99mTc energy window.Therefore, in this study, we aimed to ...

متن کاملFactors influencing the pattern and intensity of myocardial 18F-FDG uptake in oncologic PET-CT imaging
Introduction:Myocardial 18F-FDG uptake is highly variable in oncologic whole body 18F-FDG PET/CT studies, ranging from quite intense to minimal distribution. Intense or heterogeneous myocardial 18F-FDG uptake is undesirable as it may interfere with the visual or quantitative evaluation of tumoral invasion and metastases in pericardium, myocardiu...
متن کاملEvaluation of 99mTc-3PRGD2 integrin receptor imaging in hepatocellular carcinoma tumour-bearing mice: comparison with 18F-FDG metabolic imaging
OBJECTIVE Our study was designed to explore the utility of 99mTc-HYNIC-PEG4-E[PEG4-c(RGDfK)]2 (99mTc-3PRGD2) for the detection of hepatocellular carcinoma (HCC) and specifically to compare the diagnostic performance of 99mTc-3PRGD2 integrin receptor imaging and 2-18-fluoro-2-deoxy-D-glucose (18F-FDG) metabolic imaging in a nude mouse model. METHODS 99mTc-3PRGD2 was synthesized using a HYNIC-3...
