15,16 Consequently, all patients with a CPT should undergo magnetic resonance imaging (MRI) with gadolinium contrast of their entire craniospinal axis as part of the initial staging workup. In addition, a diagnostic lumbar puncture for CSF cytology is recommended. Radiologic Appearance CPP and ...

MRI data was pre-processed with Freesurfer 6.0.059,60 to estimate cortical thickness, surface area and subcortical volumes. Data was processed on King’s College London HPC infrastructure Rosalind (https://rosalind.kcl.ac.uk), with the standard recon-all procedure, consisting of motion correction...
Functional MRI analysis shows failure to activate the vmPFC while OCD patients are recalling the extinction memory. These patterns of psychophysiological and brain dysfunctions observed in the OCD cohort examined herein resembles those recently reported in PTSD patients. Moreover, preliminary data from ...
However, this kind of gap-dependent permeability merely exists in WHO-defined grade II astrocytomas and oligodendrogliomas vessels [19], which leads to low permeability of contrast agents for CT and MRI and following faint contrast signals in the tumor. Similar to most peripheral tumors, ...
Functional MRI acquisitions were time-locked to the onset of the task. During the same experimental session, a high-resolution T1-weighted image (fast spoiled gradient-recalled echo sequence, repetition time = 8 milliseconds, echo time = 3 milliseconds, inversion time = 450 milliseconds, flip ...
Upon nasal administration, the nanoparticles significantly reduced the volume of a tumour induced by implanting RG2 cells in the rat brain (55% reduction by MRI analysis). The antitumor effect obtained was comparable to that obtained with the same nanoparticles administered intravenou...
With the increasing availability of magnetic resonance imaging (MRI), acute encephalopathy has been subclassified into several clinico-radiological syndromes such as acute necrotizing encephalopathy (ANE) [58], hemorrhagic shock and encephalopathy syndrome (HSES) [31, 50], acute encephalopathy with biphas...
The classification was performed using a T1-weighted contrast-enhanced MRI image database which contains three tumor types. As input, we used whole images, so it was not necessary to perform any preprocessing or segmentation of the tumors. Our designed neural network is simpler than Appl. Sci....
Within the last decade, neuroimaging combined with online experience sampling—wherein people are intermittently prompted to report their current thoughts—has become a well-established, powerful method to link brain dynamics with mind-wandering episodes11,12,13,14,15,16. Initial functional MRI (fMRI...
