To assess whether MRI Primovist could replace 99mTc-mebrofenin HBS as a preoperative functional liver assessment in addition to CT-volumetry in predicting PHLF in patients with resectable pCCA who require a major liver resection.
The primary objective of the study is to determine feasibility of CEA assessments at home using (automated) capillary sampling. Home based (automated) capillary sampling will be considered feasible if a success rate of 85% or greater has been…
The aim of this study is to measure eCAPs intraoperatively (and perform electrocochleography [ECochG] in case of any residual hearing) and to estimate cochlear health in these patients by applying insights gained from our guinea pig experiments.
Primary objective:To relate pulmonary fibroblast activity, measured by FAPI-PET/CT at least 3 months after hospital discharge, to interstitial lung abnormalities on HRCT at the same time point in post-acute COVID-19 patients with respiratory…
Primary Objective: The Primary outcome is to evaluate the sensitivity of the ACCmax compared to the currently advised diagnostic method the ABI.Secondary ObjectivesTo evaluate the sensitivity, specificity, positive and negative likelihood ratios of…
This study aims to validate the Corsano CardioWatch 287-2 for the continuous monitoring of heart rate at <= 4 bpm root mean squared error (RMSE); interbeat intervals at <= 50 ms RMSE; breathing rate at <= 2 brpm RMSE; and…
(1) to create and train an algorithm to generate synthetic CT images of the craniofacial area(2) to evaluate the resulting synthetic CT images in terms of geometrical accurate visualization of the craniofacial osseous structures compared to the…
The primary objective of this study is to validate the prediction model on the effect of a standardized mixed meal challenge on postprandial triglyceride levels in a heterogenous group of middle-aged, overweight to obese individuals. The secondary…
This study has been transitioned to CTIS with ID 2024-513843-10-00 check the CTIS register for the current data. Primary objective: Assess the short term safety and tolerability of 68Ga-SATO in pediatric patients with NBLSecondary objectives: -…
The primary objective in this trial is to evaluate the use of MRI and contrast enhanced mammography after using MagTrace® to perform a breast conserving surgery and a sentinel node biopsy.
To detect differences between ACC patients and controls without ACC, and between the diseased and healthy adrenal gland of ACC patients, in microRNA (miRNA), circulating cell-free tumor DNA (ctDNA), circulating tumor cells (CTCs), and steroid…
Primary objectiveThe primary objective is to evaluate whether a standard pre- and postdilatation of the modern DES results in a more optimal stent implantation compared to DS as evaluated by OCT in patients with stable coronary artery disease.…
To assess the following research questions: 1. Does the use of 3D virtual preoperative planning of surgery improve functional outcome as measured by Patient-Reported Outcome in comparison to conventional surgery (using conventional radiographs and/…
The objective of this study is to validate the tHb determined by sOCT by comparing it to the tHb from invasive blood sampling. From this comparison, we aim to optimize our data analysis procedure for in vivo sOCT measurements. We also aim to…
To explore the feasibility and opportunities for new imaging procedures, of relevance of Amsterdam UMC prioritized areas, that a ultra-high sensitivity total body PET-CT system can offer for improving diagnosis and dose reduction.The protocol…
This study has three specific objectives:1) to explore how the participants* intercorporal bone grafts HU develop over time in the first two years after fusion surgery.2) to explore the interobserver reliability of the HU measurements.3) to explore…
Through the utilization of fMRI and DUS we aim to illustrate the physiological change a kidney graft undergoes during a transplantation trajectory from donor to recipient. Secondarily, we intend to establish a baseline reference for normal…
The primary objective of this study is to describe and to quantify the change in cardiac mechanoenergetics, expressed by PVL monitoring (reflected by the parameters stroke work, potential energy and pressure-volume area), in patients undergoing…
We aim to identify the utility of blood-based biomarkers for AD. Our first objective is to determine percent agreement between plasma biomarkers and clinical diagnosis set in a memory clinic. In summary: testing the agreement between plasma…
Primary objective: in this study, we want to investigate the performance of FH identification with a new approach using existing clinical laboratory data in which patients with severe hypercholesterolemia (LDL-C > 99.5th percentile for age…
