Assessment of Bone Material Strength by Microindentation in vivo after Fracture or Surgery-related Immobilization

To compare Bone Material Strength of the tibia at the side of a fracture or arhtrodesis with that of the opposite tibia in patients who had been immobilized for at least 6 weeks after a recently sustained fracture of the ankle of calcaneus or after…

Viscosity of PMMA Bone Cement in Percutaneous Vertebroplasty for Osteoporotic Vertebral Compression Fractures: A Randomized Controlled Trial

Establishment whether usage of high viscosity PMMA bone cement in PVP for OVCFs leads to a reduction in leakage incidence compared to usage of conventional (low-medium) viscosity PMMA bone cement in PVP for OVCFs.Since evidence is scarce or…

Towards endoscopic ultrasound and 11C-5-HTP PET screening for pancreatic neuroendocrine tumors in Multiple Endocrine Neoplasia type 1 and Von Hippel Lindau disease

To determine the additiotinal value of EUS and 11C-5-HTP PET scan for detection of pancreatic NET.

COVID-19 patients with severe or fatal outcome have a pre-existing state of immune-aging; exploring determinants of disease

To assess whether premature aging of both the innate and adaptive arms of theimmune system are associated with COVID-19 morbidity and mortality. Identify immune (andendocrine) parameters that might be of use in predicting disease progression and…

Healthy volunteer study for development of ASL MR for perfusion imaging of salivary glands

Primary: to determine normal values and test-retest variation of salivary gland perfusion using ASL in healthy volunteers. Secondary: to test the procedure by measuring possible perfusion differences during stimulated or suppressed salivation.
