In MRI, the main magnetic field polarizes the electron cloud of a molecule, generating a
chemical shift for observer protons within the molecule and a magnetic susceptibility …

Magnetic susceptibility describes the magnetizability of a material to an applied magnetic
field and represents an important parameter in the field of MRI. With the recently introduced …

Quantitative susceptibility map** (QSM) has enabled magnetic resonance imaging (MRI)
of tissue magnetic susceptibility to advance from simple qualitative detection of hypointense …

The magnetic susceptibility of tissue can be determined in gradient echo MRI by
deconvolving the local magnetic field with the magnetic field generated by a unit dipole. This …

The conundrum of modality selection in clinical diagnostic imaging is that modalities with the
highest sensitivity have relatively poor resolution, while those with high resolution have …

The diagnosis of many neurologic diseases benefits from the ability to quantitatively assess
iron in the brain. Paramagnetic iron modifies the magnetic susceptibility causing magnetic …

Ultrasmall iron oxide nanoparticles have recently attracted much attention as T1 (positive)
contrast agents for magnetic resonance imaging to serve as safer alternatives to gadolinium …

Mesoporous silica-coated hollow manganese oxide (HMnO@ mSiO2) nanoparticles were
developed as a novel T 1 magnetic resonance imaging (MRI) contrast agent. We …

A comprehensive classification of contrast agents currently used or under development for
magnetic resonance imaging (MRI) is presented. Agents based on small chelates …

Contrast in magnetic resonance imaging (MRI) arises from changes in the intensity of the
proton signal of water between voxels (essentially, the 3D counterpart of pixels). Differences …
