Although some studies have shown neuroimaging and neuropsychological alterations in post-COVID-19 patients, fewer combined neuroimaging and neuropsychology evaluations of individuals who presented a mild acute infection. Here we investigated cognitive dy
Numerical simulations and MR thermometry confirmed the feasibility of spatio-temporal uniform hyperthermia (± 0.5 °C) inside the medullar cavity using a fixed focal point sonication. This result was obtained by the combination of several factors: an optimal positioning of the focal spot in the ...
No differences were observed in blood biomarkers, including C-reactive protein (CRP), high-sensitivity troponin T (hs-TropT) and N-terminal pro-brain natriuretic peptide (NT-proBNP), either among participants or compared to controls. Structural heart disease by way of reduced left ventricular ...
To address this knowledge gap, we explored potential neuroprotective effects derived from polyphenols in pomegranate juice in older volunteers with mild memory complaints in a placebo-controlled, randomized, and double-blind trial and measured three aspects: (1) metabolites of pomegranate juice using blo...
The BOLD resting-state functional MRI protocol consisted of a gradient echo-planar sequence with FOV 230 × 230 mm, matrix 96 × 96, slice thickness 4 mm, TE = 35 ms, TR = 3000 ms, flip angle = 90°, and voxel size of 2.4 × 2.4x4 mm. The acquisition...
prepared rapid acquisition with gradient echo (3D-MPRAGE) using the following acquisition parameters: 176 sagittal slices; thickness = 1 mm; TR = 8.2 ms; TE = 3.2 ms; flip angle = 8°; FOV = 250 × 250 mm; and matrix = 256 × 256. ...
MRI was performed with a 3T MR750 scanner (GE Medical Systems, Milwaukee, WI). Diffusion﹚eighted images were acquired using a spin〆cho echo﹑lanar﹊maging sequence with TR/TE/ = 4000 ms/103.5 ms, with along 64 nonヽollinear directions using b﹙alues of 0 and 1000 s/mm2. FBA was...
Functional MRI was acquired using gradient echo planar imaging with the following parameters: TR 2000 ms; TE 20 ms; FOV 224x224mm; voxel size 3.5 × 3.62 × 3.5 mm. To account for T1 equilibrium effects, image acquisition was preceded by a preparation phase. The following sequences were ...
In addition, cranial MRI and 1H MR spectroscopy were ob- tained in 10 patients using a superconducting 1.5-T magnet (Magneton, Siemens) using spin-echo pulse sequences. T1- weighted and proton density-weighted images [transmission time (TR), 2500; echo time (TE) 15/90] were acquired in ...
all participants on a Siemens 3.0 T Prisma MRI scanner (Siemens Healthcare, Erlangen, Germany) at the Functional Neuroimaging Department, Beijing Neurosurgical Institute, Capital Medical University, using a single-shot echo-planar imaging (EPI) sequence (TR = 8000 ms, TE = 60 ms)...
