Accelerated Brain Aging in Patients With Obsessive-Compulsive Disorder
Frontiers in Psychiatry, 2022 Obsessive-compulsive disorder (OCD) may be accompanied by an accelerated structural decline of the brain with age compared to healthy controls (HCs); however, this has yet to be proven. To answer this question, we built a brain age prediction model using

Nuclear Magnetic Resonance Imaging with 90 nm Resolution [PDF]
Nature Nanotech. 2, 301 (2007), 2007 Magnetic resonance imaging, based on the manipulation and detection of nuclear spins, is a powerful imaging technique that typically operates on the scale of millimeters to microns. Using magnetic resonance force microscopy, we have demonstrated that magnetic resonance imaging of nuclear spins can be extended to a spatial resolution better than 100 nm.

Magnetic Resonance Imaging of Electrolysis. [PDF]
Scientific Reports, 2015 AbstractThis study explores the hypothesis that Magnetic Resonance Imaging (MRI) can image the process of electrolysis by detecting pH fronts. The study has relevance to real time control of cell ablation with electrolysis. To investigate the hypothesis we compare the following MR imaging sequences: T1 weighted, T2 weighted and Proton Density (PD ...

Accelerated nanoscale magnetic resonance imaging through phase multiplexing [PDF]
Applied Physics Letters 106, 213101 (2015), 2014 We report a method for accelerated nanoscale nuclear magnetic resonance imaging by detecting several signals in parallel. Our technique relies on phase multiplexing, where the signals from different nuclear spin ensembles are encoded in the phase of an ultrasensitive magnetic detector.

Magnetic resonance imaging of perfusion [PDF]
Magnetic Resonance in Medicine, 1990 AbstractRecent developments have shown that diffusion and blood microcirculation (perfusion) could be imaged and measured noninvasively by MRI. The purpose of this presentation is to overview the different approaches that use B0 field gradients to monitor diffusion / perfusion. The principles of these different methods are discussed together with their

Off-resonance artifact correction for magnetic resonance imaging: a review [PDF]
arXiv, 2022 In magnetic resonance imaging (MRI), inhomogeneity in the main magnetic field used for imaging, referred to as off-resonance, can lead to image artifacts ranging from mild to severe depending on the application. Off-resonance artifacts, such as signal loss, geometric distortions, and blurring, can compromise the clinical and scientific utility of MR ...

Imaging of atherosclerosis: magnetic resonance imaging [PDF]
European Heart Journal, 2011 Atherosclerosis and its thrombotic complications are the major cause of morbidity and mortality in the industrialized countries. Despite advances in our understanding of the pathophysiology, pathogenesis, and new treatment modalities, the absence of an adequate non-invasive imaging tool for early detection limits both the prevention and treatment of ...
