[Prognostic value of interim PET/CT in non-hodgkin lymphoma].

Background: The prognosis of Non-Hodgkin Lymphoma (NHL) depends on the type of lymphoma, the extension of the disease and the response to therapy.

Aim: To evaluate the prognostic value of pretreatment and interim PET/CT compared to classic prognosis factors and body composition measurement (sarcopenia, adipopenia) in patients with recently diagnosed NHL.

Material And Methods: Patients with recently diagnosed NHL who had staging 18F-FDG PET/CT performed between December 2008 and August 2018 were selected.

Two-part implant abutments with titanium and ceramic components: Surface modification affects retention forces-An in-vitro study.

Objectives: Two-part abutments consist of titanium base and ceramic coping. Their long-term success is largely determined by the mechanical stability. The aim of the present study was to investigate the retention forces of two-part implant abutments.
