Introduction to Brain and Medical Images [PDF]
arXiv, 2021 This article is based on the first chapter of book Chung (2013), where brain and medical images are introduced. The most widely used brain imaging modalities are magnetic resonance images (MRI), functional-MRI (fMRI) and diffusion tensor images (DTI). A brief introduction to each imaging modality is explained.

Sacral tumours on MRI : a pictorial essay [PDF]
, 2019 Tumours of the sacrum can be primary or secondary. Since the sacrum is rich in haematopoietic bone marrow, bone metastases are the most frequent aetiologies.

Object-related activity revealed by functional magnetic resonance imaging in human occipital cortex.
Proceedings of the National Academy of Sciences of the United States of America, 1995 The stages of integration leading from local feature analysis to object recognition were explored in human visual cortex by using the technique of functional magnetic resonance imaging. Here we report evidence for object-related activation.

Charged Particle Resonance In Induction Field [PDF]
Phys. Plasmas 1 June 2024; 31 (6): 062104Starting from First Principles, the space charge manipulation of charged particles in an induction field in free space based on an unique Magnetic field strength and its oscillation Frequency relationship is demonstrated numerically and theoretically. The Larmor precession frequency for a time varying magnetic field, instead of conventionally followed ...

High-Resolution Nanoscale Solid-State Nuclear Magnetic Resonance Spectroscopy
, 2017 We present a new method for high-resolution nanoscale magnetic resonance imaging (nano-MRI) that combines the high spin sensitivity of nanowire-based magnetic resonance detection with high spectral resolution nuclear magnetic resonance (NMR) spectroscopy.

Nanoparticles in magnetic resonance imaging: from simple to dual contrast agents
International Journal of Nanomedicine, 2015 Magnetic resonance imaging (MRI) has become one of the most widely used and powerful tools for noninvasive clinical diagnosis owing to its high degree of soft tissue contrast, spatial resolution, and depth of penetration.
