Hybrid PET/MRI systematically offers a complementary combination of two modalities that has often proven itself superior to the single modality approach in the diagnostic work-up of many neurological and psychiatric diseases. Emerging PET tracers, technical advances in multiparametric MRI and obvious workflow advantages may lead to a significant improvement(More)
INTRODUCTION Critically ill patients often require renal replacement therapy accompanied by thrombocytopenia. Thrombocytopenia during heparin anticoagulation may be due to heparin-induced thrombocytopenia with need for alternative anticoagulation. Therefore, we compared argatroban and lepirudin in critically ill surgical patients. METHODS Following(More)
AIM The aim of this study was to examine the esthetic parameters that are applied, more or less unconsciously, in deciding for or against orthodontic space closure in the case of aplasia or traumatic loss of lateral incisors. MATERIALS AND METHOD The width-height index for teeth 13 to 23 was measured on 200 dental students. The VITA Easyshade system was(More)

BACKGROUND In PET/MRI, linear photon attenuation coefficients for attenuation correction (AC) cannot be directly derived, and cortical bone is, so far, usually not considered. This results in an underestimation of the average PET signal in PET/MRI. Recently introduced MR-AC methods predicting bone information from anatomic MRI or proton density-weighted(More)
