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

Quantifying mixing using magnetic resonance imaging. [PDF]
, 2012 Mixing is a unit operation that combines two or more components into a homogeneous mixture. This work involves mixing two viscous liquid streams using an in-line static mixer. The mixer is a split-and-recombine design that employs shear and extensional
