Value of multimodality image registration of cone-beam CT and CT in adrenal vein sampling procedures in increasing success rate

To determine the value of multimodality image registration of cone-beam CT (CBCT) and CT in increasing the success rate of adrenal vein sampling procedure compared to procedures without CBCT guidance.

Towards cost-effective diagnostic management of patients with primary aldosteronism: adrenal vein sampling or CT-scan?

Here we propose to perform a prospective, randomized, multicenter study that compares effectiveness of AVS with effectiveness of CT-scanning for the diagnosis of PA subtype. There is no criterion standard for accuracy of the diagnosis of PA-subtype…

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…

Comparison of outcome with three different needles in ultrasound assisted fine needle aspiration cytology (FNAC) of the thyroidal gland.

Primary objective: to obtain an comparison of the diagnostic result after an ultrasound assisted fine needle aspiration cytology (FNAC) of the thyroidal gland by use of a smaller diameter (25G) and / or a special coating.
