7T Epilepsy Task Force Consensus Recommendations on the Use of 7T MRI in Clinical Practice [PDF]

open access: yesNeurology, 2021
Identifying a structural brain lesion on MRI has important implications in epilepsy and is the most important factor that correlates with seizure freedom after surgery in patients with drug-resistant focal onset epilepsy. However, at conventional magnetic field strengths (1.5 and 3T), only approximately 60%-85% of MRI examinations reveal such lesions ...

Individualized cognitive neuroscience needs 7T: Comparing numerosity maps at 3T and 7T MRI

open access: yesNeuroImage, 2021
The field of cognitive neuroscience is weighing evidence about whether to move from the current standard field strength of 3 Tesla (3T) to ultra-high field (UHF) of 7T and above. The present study contributes to the evidence by comparing a computational cognitive neuroscience paradigm at 3T and 7T.

Radiological and Clinical Value of 7T MRI for Evaluating 3T-Visible Lesions in Pharmacoresistant Focal Epilepsies

open access: yesFrontiers in Neurology, 2021
Objective: The recent FDA approval of the first 7T MRI scanner for clinical diagnostic use in October 2017 will likely increase the utilization of 7T for epilepsy presurgical evaluation. This study aims at accessing the radiological and clinical value of

7T MRI Versus 3T MRI of the Brain in Professional Fighters and Patients With Head Trauma

open access: yesNeurotrauma Reports, 2023
Many studies have investigated the imaging sequelae of repetitive head trauma with mixed results, particularly with regard to the detection of intracranial white matter changes (WMCs) and cerebral microhemorrhages (CMHs) on ?3 Tesla (T) field magnetic ...

7T MR Safety

open access: yesJournal of Magnetic Resonance Imaging, 2020
Magnetic resonance imaging and spectroscopy (MRI/MRS) at 7T represents an exciting advance in MR technology, with intriguing possibilities to enhance image spatial, spectral, and contrast resolution. To ensure the safe use of this technology while still harnessing its potential, clinical staff and researchers need to be cognizant of some safety ...

Safety for Human MR Scanners at 7T

open access: yesMagnetic Resonance in Medical Sciences, 2022
After introduction of the first human 7 tesla (7T) system in 1999, 7T MR systems have been employed as one of the most advanced platforms for human MR research for more than 20 years. Currently, two 7T MR models are approved for clinical use in the U.S.A. The approval facilitated introduction of the 7T system, summing up to around 100 worldwide.

Sharpness in motion corrected quantitative imaging at 7T [PDF]

open access: yesNeuroImage, 2020
Sub-millimeter imaging at 7T has opened new possibilities for qualitatively and quantitatively studying brain structure as it evolves throughout the life span. However, subject motion introduces image blurring on the order of magnitude of the spatial resolution and is thus detrimental to image quality.

7T MRI of spinal cord injury [PDF]

open access: yesNeurology, 2012
A man with 25 years of mild left neck, arm, and leg paresthesias had initial MRI in 1996 identifying a left C3-4 dorsal horn cavernous hemangioma. In 1997, hemorrhage (C3-7) and resection induced left arm > leg proprioceptive loss and clumsiness. Three months after surgical resection, left upper-body pain recurred; 2 years later, disabling colocalizing

A paired dataset of T1- and T2-weighted MRI at 3 Tesla and 7 Tesla

open access: yesScientific Data, 2023
Brain magnetic resonance imaging (MRI) provides detailed soft tissue contrasts that are critical for disease diagnosis and neuroscience research. Higher MRI resolution typically comes at the cost of signal-to-noise ratio (SNR) and tissue contrast ...
