Evaluating Infrasonic Hemodynography
This comparative diagnostic accuracy study will determine the accuracy of a noninvasive wearable infrasonic sensor to detect the mechanical, electrical, and hemodynamic function of the cardiovascular system.
MRI Biomarkers Predictive of Disability Progression in Patients With Multiple Sclerosis
The transition from relapsing-remitting multiple sclerosis to secondarily progressive multiple sclerosis (SPMS) is difficult to identify. Typically, SPMS is diagnosed retrospectively, with a significant delay, on the basis of a clinical history of progressive worsening, independent of relapses. Thus, SPMS is often associated with a considerable period of diagnostic uncertainty. …
Feasibility of Online MR-guided Radiotherapy on a 1.5T MR-Linac
This study investigates the feasibility of imaging and treatment on a novel 1.5 T MR-Linac radiotherapy hybrid device.
New Imaging Biomarkers Predictive of MA Progression
The pathophysiology of AD is complex. In addition to amyloid plaques and neurofibrillary degeneration, there is a metabolic alteration of the energy pathways, oxidative phosphorylation and glycolysis, which are involved in brain function. Several authors have shown a series of early metabolic dysregulations via an increase in phosphorylation at the …
MR Imaging Study Using the Northern Alberta Linac-MR (Northern LIGHTs - 1)
Cancers are often treated with external beam radiotherapy. Current radiotherapy treatments are performed using computed tomography (also known as CT) scans which may not always clearly identify the cancer. In some instances, magnetic resonance imaging (MRI) may be able to better identify cancers. Therefore, efforts are currently underway to use …
Serial MR Imaging and MR Spectroscopic Imaging for the Characterization of Lower Grade Glioma
This trial studies how well serial magnetic resonance (MR) imaging and MR spectroscopic imaging work in characterizing lower grade glioma. Diagnostic procedures, such as MR imaging and MR spectroscopic imaging, may detect serial changes in lower grade glioma. This study may help researchers learn more about practical ways of evaluating …
The MR-Linac Technical Feasibility Protocol
Radiation therapy is predominantly based on a Computed Tomography (CT) scan obtained during the treatment planning phase. During the course of radiotherapy, however, both the tumor and organs at risk (OAR) are variable in position, shape and size between fractions, and during beam delivery within one treatment fraction. Around the …
MR-guided Focused Ultrasound Plus GCase
The goal of this study is to establish safety and feasibility of intracerebral delivery of GCase via MRgFUS. This technique may offer potential benefits given the exposure of the putamen to GCase in animal models has been shown to be efficacious in improving Parkinson's disease pathology and phenotype.
The New Combined PET-MR System NextGen PET-MR With Syngo MR XA80A: Evaluation of Diagnostic Image Quality and Usability (Software and Hardware) in the Clinical Setting.
This clinical investigation is used to evaluate the novel PET-MR scanner and it is a clinical investigation under MDR. The focus is on the evaluation of the diagnostic image quality in a clinical setting, considering the speed of the examination and the new functionalities to minimize the patient's lying times. …
MR-guidance in Chemoradiotherapy for Cervical Cancer
Concurrent chemoradiotherapy (CCRT), consisting of external beam radiotherapy (EBRT) and chemotherapy, followed by brachytherapy (BT) is the standard of care for patients with locally advanced cervical carcinoma. In current clinical practice, conventionally, one radiotherapy plan based on the initial planning computed tomography (CT) and magnetic resonance imaging (MRI) scan of …
