Trigeminal nerve and pathologies in magnetic resonance imaging : a pictorial review [PDF]
, 2018 A variety of conditions may affect the trigeminal nerve. Magnetic resonance imaging is the modality of choice when trigeminal nerve pathology is suspected, and this modality plays an essential role in detecting causes. This review illustrates some of the

Embroidered Coils for Magnetic Resonance Sensors [PDF]
, 2013 Magnetic resonance imaging is a widely used technique for medical and materials imaging. Even though the objects being imaged are often irregularly shaped, suitable coils permitting the measurement of the radio-frequency signal in these systems are ...

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 ...
