Frontiers in Psychiatry, 2022 BackgroundMajor depressive disorder (MDD) is associated with dysfunction of the reward system. As an important node in the reward system, the resting-state functional connectivity of the nucleus accumbens (NAc) is related to the etiology of MDD. However,

Nanoscale magnetic resonance imaging [PDF]
Proceedings of the National Academy of Sciences, 2009 We have combined ultrasensitive magnetic resonance force microscopy (MRFM) with 3D image reconstruction to achieve magnetic resonance imaging (MRI) with resolution <10 nm. The image reconstruction converts measured magnetic force data into a 3D map of nuclear spin density, taking advantage of the unique characteristics of the “resonant slice” that ...

Magnetic resonance imaging methodology [PDF]
European Journal of Nuclear Medicine and Molecular Imaging, 2008 Magnetic resonance (MR) methods are non-invasive techniques to provide detailed, multi-parametric information on human anatomy, function and metabolism. Sensitivity, specificity, spatial and temporal resolution may, however, vary depending on hardware (e.g., field strength, gradient strength and speed) and software (optimised measurement protocols and ...

Fetal Magnetic Resonance Imaging
Topics in Magnetic Resonance Imaging, 2001 Fast magnetic resonance imaging (MRI) has revolutionized our ability to image the fetus. Using fast scanning techniques, individual images are obtained in 300-400 ms, allowing for imaging of the fetus without sedation. MRI is most useful for evaluation of the anomalous fetal central nervous system, for further characterization of complex anomalies not ...

Cardiovascular magnetic resonance imaging [PDF]
Clinical Cardiology, 2007 Spin-echo imaging is commonly used for assessment of cardiac and great vessel anatomy. With classic spin-echo imaging, rapidly moving blood appears dark. At current field strengths (1.5 and 3.0 tesla), cardiovascular magnetic resonance (CMR) imaging is considered safe for bioprosthetic and mechanical heart valves.

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
