Discrimination of benign and malignant human tissue during percutaneous interventions using optical spectroscopy techniques

In our previous studies using optical spectroscopy, both ex vivo and in vivo, most promising results were obtained for tissue diagnosis. Moreover, invasive procedures for biopsy or radiofrequency ablation in these tissues are all very common. Thus,…

Distinguishing children with frontal epilepsy from children with ADHD in terms the cognitive profile.

Distinguishing frontal lobe epilepsy from ADHD in terms of working memory.

Characterization and localization of microstructural changes in brain tissue in Neuropsychiatric Systemic Lupus Erythematosus (NPSLE)

• To increase the sensitivity of the current MRI methods for detecting the changes caused by NPSLE through the scans made on the 7 Tesla scanner, since the higher field strength will lead to a higher signal to noise ratio and higher resolution. • To…

Treatment of Central Sleep Apnea Syndrome with low-pressure nasal continuous positive airway pressure and rebreathing.

Primary objective:To show that addition of dead space to low-pressure nCPAP (which is usually not effective but can be relatively well tolerated) makes the therapy effective and diminishes the apnea hypopnea index with >10/hour in patients…

Feasibility of MRI-imaging of the Affinis short shoulder prosthesis

To Establish the usefulness of MRI for assessment of the rotator cuff in patients with an Affinis short prosthesis implanted in the shoulder.

The real distribution of microbiota along the colonic mucosa using a novel device capable of taking *protected* biopsies

Primary Objective: to show the differences in distribution of microbial DNA proximal versus distal in the colon as well as luminal composition versus mucosa adherent. Secondary Objective: to test whether bowel lavage has influence on the microbial…

Improvement of Diagnostic mEthods for ALlergy assessment. Cashew allergy in children as a showcase (IDEAL study)

To improve diagnostic tools for food/cashew nut allergies with the use of Mediator Release Assays.Genetic component of cashewnut allergy.

Cerebrovascular manifestations of Hereditary Hemorrhagic Telangiectasia: a look beyond AVMs | A study of the prevalence of structural brain changes in HHT and an assessment of the MR cerebrovascular reactivity of HHT patients

The objectives of this study are:1. to evaluate the occurrence and distribution of structural brain changes in HHT patients with and without pulmonary AVMs as compared to healthy age matched controls;2. to evaluate the (autoregulatory) function of…

Evaluation of the CAP-value for quantitating liver steatosis using 1H-MRS and liver biopsy as reference standard

Main objective: investigate the correlation between CAP-values with fat percentages found at 1H-MR Spectroscopy and steatosis grade at liver biopsy. Secondary objectives: investigate the reproducibility of CAP-measurements; investigate the…

Non-invasive nodal staging in breast cancer with MRI Lymphography using gadofosveset.

The aim of this pilot-study is to examine the accuracy of MRL compared to current nodal staging methods. We expect anacceptable accuracy of the MRL based on earlier studies with gadofosveset enhanced MRI in rectum cancer patients. Then the MRL could…

Varenicline, a partial nicotinic receptor agonist, for the treatment of excessive daytime sleepiness in Parkinson*s disease: a placebo-controlled cross-over study

This study is aimed to determine the efficacy of varenicline in reducing EDS in PD patients.

ROBot-aided system Identification: a novel tool for diagnosis and assessment in Neurological rehabilitation: *ROBIN*

Primary objective of this study is to assess the reliability, validity, and diagnostic value of the neuromechanical parameters of joint impedance estimated by nonlinear SIPE technology in patients with a spastic paresis.

Predicting ovarian response in artificial insemination with low stimulation

This large prospective multi-center cohort study aims to identify patient*s characteristics that significantly influence ovarian response to mild stimulation with a fixed dose of 75 IU recombinant FSH

A phase II prospective imaging study evaluating the utility of pre-treatment zirconium-89 labelled trastuzumab PET/CT and an early FDG-PET/CT response to identify patients with advanced HER-2 positive breast cancer unlikely to benefit from a novel anti-HER2 therapy: T-DM1

The primary objective (on lesion-based analysis) is to show that pre-treatment 89Zr-trastuzumab PET/CT is able to select lesions not responding morphologically from treatment with T-DM1 (applying RECIST 1.0 criteria)Secondary Objectives and…
