Increasing Diagnosis Rates While Reducing Examination Time: Can MR Fingerprinting Deliver on Its Promise?

Start date: September 1, 2018
Phase:
Study type: Observational

Magnetic Resonance Imaging (MRI) is an excellent method for diagnosis and staging of brain disease. However, lengthy scan times and sensitivity to patient motion limit its efficacy. To address this, a novel method has recently been demonstrated, called MR Fingerprinting (MRF). The investigators' improved implementation of MRF, featuring fully-quantitative data and a reduced sensitivity to patient motion, can be used to acquire an anatomical exam in less than five minutes at a standard resolution. The potential for wide applicability of this technique, combined with an implied reduction in complexity and cost of MRI exams, has generated wide interest. However, published studies have been limited to demonstrations in healthy volunteers, and the effectiveness of MRF in the clinical practice has not yet been proven. Here, the investigators aim to assess the efficacy of MRF in performing diagnostic exams avoiding sedation in children and for increasing diagnosis rates in challenging adult patients.

NCT ID: NCT06246019 Enrolling by invitation - Alzheimer Disease Clinical Trials

The Clinical Impact of the Novel Alzheimer's Blood-based Biomarkers

PLASMAR
Start date: February 7, 2024
Phase:
Study type: Observational [Patient Registry]

The goal of this observational study is to determine whether the early adoption of blood-based biomarkers for Alzheimer's disease is associated with an impact on etiological diagnosis, patient's management, emotional impact, patient's preferences and cost-effectiveness in patients presenting with cognitive complaints in a Cognitive Disorders Unit from a public hospital. The main questions it aims to answer are: 1. Does the early adoption of blood-based biomarkers in clinical practice enable an earlier etiologic diagnosis with high confidence compared to the late adoption of blood-based biomarkers in the patients with cognitive complaints that are admitted in a Cognitive Disorders Unit? 2. Is the early adoption of blood-based biomarkers in clinical practice associated with changes in clinical management compared to their late adoption? 3. Is the early adoption of blood-based biomarkers in clinical practice associated with a lower emotional impact in the patients and their study partners/caregivers compared to their late adoption? 4. Are blood-based biomarkers better tolerated than other tests and preferred by patients for the diagnostic work-up? 5. Does blood-based biomarkers have an impact in the cost of the diagnostic workup and clinical management of the patients that are admitted in a Cognitive Disorders Unit? Participants will be asked to: - Perform a blood extraction for blood-based biomarkers analysis at the beginning of the study. - Complete specific scales in each visit. Researchers will compare the group in which blood biomarkers are delivered at 3 months with the group in which they are delivered at 9 months to assess whether early adoption of blood-based biomarkers is associated with an impact on etiological diagnosis, patient's management, emotional impact, patient's preferences and cost-effectiveness in a specialized memory unit.

NCT ID: NCT06211803 Completed - Clinical trials for Neuroendocrine Tumors

Clinical Application of the Prototype J-PET Device

JPETClinic
Start date: March 11, 2022
Phase:
Study type: Observational [Patient Registry]

Positron emission tomography (PET) is a diagnostic imaging technique that uses positron emission (e-) to image changes in diagnosed tissues. Detector systems are an important part of PET scanners. They can convert gamma photons into fluorescent photons to obtain information about energy, time and position, of the gamma photons obtained through the use of an appropriate positron-emitting radiopharmaceutical. Conventional PET scanners are expensive mostly because they require the use of LSO (lutetium oxyorthosilicate) or LYSO (lutetium yttrium oxyorthosilicate) scintillation crystals. Such crystal scintillators are very costly and difficult to obtain, which limits accessibility of the PET- scanners. The prototype J-PET scanner tested in this trial uses plastic scintillators in which different physical phenomena occur compared to crystal scintillators. In addition, the J-PET scanner prototype is equipped with unique software enabling three-photon imaging, based on the annihilation resulting from the formation of the orto-positronium (o-Ps) in diagnosed tissue. The aim of this study is to demonstrate the clinical acceptability of such scanners based on plastic scintillators, which can additionally collect and process information on the lifetime of o-Ps derived from routinely used radiopharmaceuticals. Additionally, the aim of this study is to demonstrate the use of the new diagnostic indicator "positronium biomarker" in a prospective study, compared to routine diagnostic scanning.

The aim of the study is to examine: - 1) The prevalence of criminal and other disruptive behaviour in groups of different neurodegenerative diseases prior to and after the diagnosis - 2) Changes in employment, residency,income, and marital status prior to and after the neurodegenerative disease diagnosis - 3) Hospital diagnoses and reimbursable drugs prior to and after the diagnosis - 4) Causes of death in patients with neurodegenerative disease to study excess mortality of the patients

NCT ID: NCT06193252 Recruiting - Parkinson Disease Clinical Trials

Slow-SPEED-NL: Slowing Parkinson's Early Through Exercise Dosage-Netherlands

Slow-SPEED-NL
Start date: January 15, 2024
Phase: N/A
Study type: Interventional

The goal of this clinical trial is to investigate the feasibility if a remotely administered smartphone app can increase the volume and intensity of physical activity in daily life in patients with isolated Rapid Eye Movement (REM) sleep behaviour disorder over a long period of time (24 months). Participants will be tasked to achieve an incremental increase of daily steps (volume) and amount of minutes exercised at a certain heart rate (intensity) with respect to their own baseline level. Motivation with regards to physical activity will entirely be communicated through the study specific Slow Speed smartphone app. Primary outcomes will be compliance expressed as longitudinal change in digital measures of physical activity (step count) measured using a Fitbit smartwatch. Exploratory outcomes entail retention rate, completeness of remote digital biomarker assessments, digital prodromal motor and non-motor features of PD, blood biomarkers and brain imaging markers. Using these biomarkers, we aim to develop a composite score (prodromal load score) to estimate the total prodromal load. An international exercise study with fellow researchers in the United States and United Kingdom are currently in preparation (Slow-SPEED). Our intention is to analyse overlapping outcomes combined where possible through a meta-analysis plan, to obtain insight on (determinants of) heterogeneity in compliance and possible efficacy across subgroups
