Cephalometric studies of the mandible, its masticatory muscles and vasculature of growing Göttingen Minipigs-A comparative anatomical study to refine experimental mandibular surgery.
Autor: Giuliano Mario Corte, Hana Hünigen, Kenneth C Richardson, Stefan M Niehues, Johanna Plendl
Publikováno v: PLoS ONE, Vol 14, Iss 4, p e0215875 (2019)
Over many decades, the Göttingen Minipig has been used as a large animal model in experimental surgical research of the mandible. Recently several authors have raised concerns over the use of the Göttingen Minipig in this research area, observing p

Refining experimental dental implant testing in the Göttingen Minipig using 3D computed tomography-A morphometric study of the mandibular canal.
Autor: Giuliano M Corte, Johanna Plendl, Hana Hünigen, Kenneth C Richardson, Ole Gemeinhardt, Stefan M Niehues
Publikováno v: PLoS ONE, Vol 12, Iss 9, p e0184889 (2017)
This study reports morphometric and age-related data of the mandibular canal and the alveolar ridge of the Göttingen Minipig to avoid complications during in vivo testing of endosseus dental implants and to compare these data with the human anatomy.

Are Congenital Cervical Block Vertebrae a Risk Factor for Adjacent Segment Disease? A Retrospective Cross-Sectional CT and MR Imaging Study
Autor: Cornelius Jung, Patrick Asbach, Stefan M. Niehues
Publikováno v: Diagnostics, Vol 12, Iss 1, p 90 (2021)
Adjacent segment disease (ASDI) is a well-described complication of spinal fusion surgery that may ultimately lead to spinal stenosis and repeated surgical intervention. Although congenital block vertebrae also present with degenerative changes in th

Computed Tomography Imaging in Simulated Ongoing Cardiopulmonary Resuscitation: No Need to Switch Off the Chest Compression Device during Image Acquisition
Autor: Jessica Graef, Bernd A. Leidel, Keno K. Bressem, Janis L. Vahldiek, Bernd Hamm, Stefan M. Niehues
Publikováno v: Diagnostics, Vol 11, Iss 6, p 1122 (2021)
Computed tomography (CT) represents the current standard for imaging of patients with acute life-threatening diseases. As some patients present with circulatory arrest, they require cardiopulmonary resuscitation. Automated chest compression devices a

Changing the Patient's Position: Pitfalls and Benefits for Radiation Dose and Image Quality of Computed Tomography in Polytrauma
Autor: Jessica Graef, Keno K. Bressem, Patrick Asbach, Bernd Hamm, Stefan M. Niehues
Publikováno v: Diagnostics; Volume 12; Issue 11; Pages: 2661
For computed tomography (CT), representing the diagnostic standard for trauma patients, image quality is essential. The positioning of the patient’s arms next to the abdomen causes artifacts and is also considered to increase radiation exposure. Th
