2024年6月26日 · 近年来，低场64mt便携式脑部mri（pmri）的出现，为ms的诊断带来了新的可能性。 本研究旨在评估pMRI在视神经炎患者中评估空间传播（DIS）的效用，并探讨其在MS诊所中部署是否能缩短症状出现到MRI检查的时间。

NIST researchers Kalina Jordanova and Stephen Ogier conduct MRI measurements using a magnetic field strength of 64 millitesla (mT), which is at least 20 times lower than the magnetic field in conventional MRI scanners, used for example in hospital settings

2024年10月24日 · BACKGROUND AND PURPOSE: Low-field 64 mT portable brain MRI has recently shown diagnostic promise for MS. This study aimed to evaluate the utility of portable MRI (pMRI) in assessing dissemination in space (DIS) in patients presenting with optic neuritis and determine whether deploying pMRI in the MS clinic can shorten the time from symptom ...

2025年3月28日 · The study tests alignedSENSE, an iterative motion correction and reconstruction method with SENSE, for ULF MRI, with additional corrections to estimate and correct within-scan phase variations. The method was applied to in vivo brain volumetric data acquired from five healthy volunteers using a 64 mT portable MRI scanner.

2024年7月1日 · Portable low-field (64 mT) MRI appears to be safe in patients with indwelling PACs. The ability to accomplish this imaging modality enables continuous hemodynamic monitoring in a highly controlled clinical environment using intravascular pulmonary catheters without delaying the diagnosis of an important, time-sensitive acute neurological event.

2020年9月9日 · Point-of-care, 64mT MRI performs as well as conventional CT and MRI while improving patient safety. Using a portable, low-field MRI system to assess patients in the intensive care unit (ICU) for brain injury works equally as well as traditional imaging measures, a …

2024年6月26日 · BACKGROUND AND PURPOSE: Low-field 64mT portable brain MRI (pMRI) has recently shown diagnostic promise for MS. This study aimed to evaluate the utility of pMRI in assessing dissemination in space (DIS) in patients presenting with optic neuritis and determine whether deploying pMRI in the MS clinic can shorten the time from symptom onset to MRI.

Background and purpose: Low-field 64mT portable brain MRI (pMRI) has recently shown diagnostic promise for MS. This study aimed to evaluate the utility of pMRI in assessing dissemination in space (DIS) in patients presenting with optic neuritis and determine whether deploying pMRI in the MS clinic can shorten the time from symptom onset to MRI.

To compare magnetic resonance imaging (MRI), 64-slice multi-detector computed tomography (MDCT) and dual-source computed tomography (DSCT) in assessing global function parameters using a moving heart phantom. A moving heart phantom with known volumes (215-258 ml) moving at 50-100 beats per minute wa …

2025年3月29日 · Multimodal neuroimaging, in particular magnetic resonance imaging (MRI), allows for non-invasive examination of human brain structure and function across multiple scales. Precision neuroimaging ...
