PurposeAfter cochlear implantation, molecular processes at the electrode–nerve interface significantly influence the variability in clinical outcomes. The present study investigates molecular processes in a guinea pig model of cochlear implant (CI) using positron emission tomography/computed tomogra...

Cardiac involvement in sarcoidosis is difficult to diagnose due to the asymptomatic course in 95% of cases, the inaccessibility and low information content of a heart biopsy, the absence of pathological disorders in routine examination methods or their non-specificity. At the same time, it is cardia...

ABSTRACT Incidentalomas are lesions incidentally identified in patients undergoing imaging for unrelated reasons. Breast incidentalomas have a high correlation with malignancy, occurring in over 40% of cases. Consequently, their interpretation poses significant challenges for radiologists who must d...

PET/MRI is a new hybrid imaging technique that involves all achievements of modern magnetic resonance imaging (MRI) and positron emission tomography (PET). PET/MRI has advantages over other imaging methods and will most likely soon become the gold standard for visualization in some areas of radiodia...

Background. The worldwide increasing incidence of thyroid cancer (TC) is mainly due to a rise in its major form of differentiated TC (DTC): papillary. Most patients with DTC have a good prognosis; 10-year survival overall rates are as high as 85 %, but not greater than 40 % in a group of patients wi...
