The 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 (SUV). The aim of this study was
to evaluate the residual activity, according to the method used in our department.
Materials & Methods: Residual activities of the syringes used to administer FDG to 125
patients were measured and recorded, during one month. The intravenous...

Aim: 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 increase in the sub diaphragmatic tracer uptake that may
reduce image quality, interfering with image interpretation. The aim of this study was to
compare pharmacologic stress tests induced by adenosine infusion and by ATP infusion in
terms of side-effects referred by patients and the...

Epilepsy 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 patients, following EANM procedure guidelines.
Aim: the aim of the study was to retrospectively review all the performed inter-ictal 18F-FDG-PET/TC brain imaging, to assess the difficulties found during these procedures and the deviation according to guideline recommendations. We also intend to focus on...
