The technical challenge of Functional 18F-FDG-PET Brain imaging in paediatric e...
Mota, AM; Geão, A; Santos, A; Dias, L; Quaresma, P; Colarinha, PEpilepsy is a chronic brain disease, characterized by the appearance of crisis (whit or without convulsions), caused by abnormal electric activity on brain cells. Neuroimaging might be necessary in the work-up of epilepsy for localisation of the seizure focus for possible surgical cure. In our department, we started performing inter-ictal 18F-2-deoxyglucose (FDG)-PET/TC Brain imaging in 2009, in paediatric pati...
Comparing two pharmacological stress tests: adenosine vs ATP infusion – patien...
Santos, A; Geão, A; Mota, A; Pereira, E; Dias, L; Delgado, P; Figueiredo, S; Jerónimo, VAim: Adenosine and Adenosine Triphosphate (ATP) are vasodilator agents that are used for pharmacologic stress testing in Myocardial Perfusion Imaging (MPI). Both pharmaceuticals may cause side-effects that are similarly described in the literature. Although, the half-life of these molecules are slightly different and patient’s tolerance might be different. These molecules have also been associated to an inc...
Evaluating Residual Activity in 18F-FDG administration
Santos, A; Geão, A; Dias, L; Mota, A; Fernandes, MThe Positron Emission Tomography (PET) is an imaging technique, based on functional, biochemical and molecular information. It is also a useful tool in oncological examination. 18F-FluoroDeoxyGlucose (FDG) is a radiopharmaceutical widely used in nuclear medicine departments with PET facilities. FDG’s corrects administration is very important in order to achieve good images and correct Standard Uptake Values...
