imaging with 18F-fluorodeoxyglucose positron emission tomography combined with computed tomography ( 18 F-FDG-PET/CT) is the most recent modality for this purpose. 3 18 F-FDG-PET/CT has been used for baseline staging, assessment of treatment response and restaging of CRC as in many other cancers and is concerned to be more sensitive and specific imaging method than routine tools in cases of dubious recurrence and/ or metastasis. 2 , 3 CEA is expressed by a lot of epithelial tumors and its serum levels may increase in non-malignant conditions such as inflammatory

, additional imaging methods for assessing rheumatic diseases are warranted. Prolonged febrile illness with concomittant non-specific symptoms can be also a sign of PMR as well as GCA. Thus, patients may be referred during differential diagnostics of inflammatory or malignant disease to whole body positron emission tomography (PET) or a combination of PET with computed tomography (PET/CT) using 18 F-fluorodeoxyglucose ( 18 F-FDG). 11 – 14 Both GCA and PMR have their own characteristic 18 F-FDG PET/CT features, which may occur in a non-mutually exclusive manner. PMR

for structural-functional localization of the seizure focus includes electroencephalography (EEG) monitoring, magnetic resonance imaging (MRI), single photon emission tomography/computed tomography (SPECT/CT) and positron emission tomography/computed tomography (PET/CT). EEG has low sensitivity in the diagnosis of seizure disorders (25–56%). MRI is a sensitive and specific imaging modality for identifying hippocampal sclerosis as well as other lesions responsible for epilepsy. However 1–1.5 T MRI still fails to reveal approximately 20% of abnormalities in
