Static and dynamic changes of intrinsic brain local connectivity in internet gaming disorder

open access: yesBMC Psychiatry, 2023
Background Studies have revealed that intrinsic neural activity varies over time. However, the temporal variability of brain local connectivity in internet gaming disorder (IGD) remains unknown. The purpose of this study was to explore the alterations of

Autonomous Magnetic Resonance Imaging [PDF]

open access: yesMagnetic Resonance Imaging, 2020
AbstractAccess to Magnetic Resonance Imaging (MRI) across developing countries from being prohibitive to scarcely available. For example, eleven countries in Africa have no scanners. One critical limitation is the absence of skilled manpower required for MRI usage. Some of these challenges can be mitigated using autonomous MRI (AMRI) operation. In this

Magnetic resonance imaging.

open access: yesJournal of Nippon Medical School, 1989
All of the data published in the literature show that MR is more sensitive than CT in diagnosing cerebral ischemic lesions. This greater sensitivity is due to its ability to detect even the minimal changes in tissue water content which occur in the early phases of the infarct.

Imaging Methods: Magnetic Resonance Imaging

open access: yesCirculation: Cardiovascular Imaging, 2023
Myocardial inflammation occurs following activation of the cardiac immune system, producing characteristic changes in the myocardial tissue. Cardiovascular magnetic resonance is the non-invasive imaging gold standard for myocardial tissue characterization, and is able to detect image signal changes that may occur resulting from inflammation, including ...

Parallel magnetic resonance imaging [PDF]

open access: yesPhysics in Medicine and Biology, 2007
Parallel imaging has been the single biggest innovation in magnetic resonance imaging in the last decade. The use of multiple receiver coils to augment the time consuming Fourier encoding has reduced acquisition times significantly. This increase in speed comes at a time when other approaches to acquisition time reduction were reaching engineering and ...

Magnetic resonance temperature imaging [PDF]

open access: yesInternational Journal of Hyperthermia, 2005
Continuous, real-time, 3D temperature mapping during a hyperthermic procedure may provide (i) enhanced safety by visualizing temperature maps in and around the treated region, (ii) improved efficiency by adapting local energy deposition with feedback coupling algorithms and (iii) therapy end-points based on the accumulated thermal dose.
