To quantitatively compare the potential of various diffusion parameters obtained from monoexponential, biexponential, and stretched exponential diffusion-weighted imaging models kurtosis in grading gliomas.This study was approved by local ethics committee, written informed consent all subjects. Both were performed 69 patients with pathologically proven gliomas using a 3-T magnetic resonance (MR) unit. An isotropic apparent coefficient (ADC), true ADC, pseudo-ADC, perfusion fraction...
Primary insomnia can severely impair daytime function by disrupting attention and working memory imposes a danger to self others increasing the risk of accidents. We speculated that neurobiological changes impeding in primary patients would be revealed resting-state functional MRI (R-fMRI), which estimates strength cortical pathways measuring local regional correlations blood oxygen level dependent (BOLD) signs independent specific task demands. compared R-fMRI activity patterns 15 healthy...
This study investigated the topological characteristics of brain functional networks in chronic insomnia disorder (CID) patients. The resting-state magnetic resonance imaging and graph theory analysis method were applied to investigate connectome patterns among 45 CID patients 32 healthy controls. was constructed by thresholding partial correlation matrices 90 regions from an automated anatomical labeling atlas. topologic properties connectomes at both global nodal levels tested. had...
Background A pilot study has shown that real-time fMRI (rtfMRI) neurofeedback could be an alternative approach for chronic pain treatment. Considering the relative small sample of patients recruited and not strictly controlled condition, it is desirable to perform a replication as well double-blinded randomized with different control condition in patients. Here we conducted rtfMRI subgroup – postherpetic neuralgia (PHN) used sham control. We explored feasibility self-regulation rostral...
<b><i>Background:</i></b> Contemporary functional MRI (fMRI) methods can provide a wealth of information about the neural mechanisms associated with primary insomnia (PI), which centrally involve network circuits related to spatial working memory. <b><i>Methods:</i></b> A total 30 participants diagnosed PI and without atypical brain anatomy were selected along age- gender-matched healthy controls. Subjects administered Pittsburgh Sleep Quality...
The etiology and maintenance of insomnia are proposed to be associated with increased cognitive physiological arousal caused by acute stressors rumination. A core feature such hyperarousal theory involves sensory processing that interferes the onset sleep. In this work, we collected structural magnetic resonance imaging data from 35 patients primary normal sleepers applied covariance analysis investigate whether is disruptions in brain networks centered at regions (primary visual, auditory,...
Summary Substantial individual differences characterize the changes induced by total sleep deprivation on cognitive functions. Despite some progress having been achieved, mechanisms of in response to have not clearly elucidated. Cerebral metabolism resting state is among key physiological processes supporting daily function brain, and may play an important role these differences. Twenty‐two right‐handed participants (nine females 13 males) between 20 26 years old completed a mathematical...
Background Susceptibility weighted imaging (SWI) is a new MRI technique which has been proved very useful in the diagnosis of brain diseases, but few study was performed on its value prostatic diseases. The aim present to investigate SWI distinguishing prostate cancer from benign hyperplasia and detecting calcification. Methodology/Principal Findings 23 patients with 53 by biopsy were scanned 3.0T MR 16-row CT scanner. High-resolution SWI, conventional all patients. findings, especially...
We present Step-Video-T2V, a state-of-the-art text-to-video pre-trained model with 30B parameters and the ability to generate videos up 204 frames in length. A deep compression Variational Autoencoder, Video-VAE, is designed for video generation tasks, achieving 16x16 spatial 8x temporal ratios, while maintaining exceptional reconstruction quality. User prompts are encoded using two bilingual text encoders handle both English Chinese. DiT 3D full attention trained Flow Matching employed...
BACKGROUND Bile duct leaks (BDLs) are serious postsurgical adverse events. Typically, conservative management with abdominal drainage is the initial treatment option. However, prolonged without improvement can lead to biliary stricture and delay optimal timing of endoscopic retrograde cholangiopancreatography (ERCP). AIM To identify for ERCP period during which clinical observation acceptable, balancing success risk strictures. METHODS We conducted a multicenter retrospective study involving...
The purpose of this study was to investigate the effect attention control under influence auditory stimuli (music type: excited, depressing, soothing, cheerful) and tactile (vibration low frequency, high frequency) in different subjects, so as provide guidance adjust design their combinations students' learning space.We selected 24 college students (12 males 12 females) who were physically mentally healthy. Subjects asked concentrate on game test activities before after task switching...
Abstract Purpose: To prospectively evaluate noncontrast‐enhanced (NCE), time resolved, four‐dimensional (4D) magnetic resonance angiography (MRA) for assessment of cerebral arteriovenous malformation (AVM), with intraarterial digital subtraction (DSA) performed as the reference standard. Materials and Methods: Fifteen patients (ten men, five women; age range 2–59 years, mean 29.4 years) 15 untreated AVMs comprised study population. NCE 4D MRA was on a 3.0 T MR scanner. images were reviewed...
The aim of the present study was to investigate whether quantitative dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) can predict an early response in primary esophageal carcinoma patients undergoing concurrent chemoradiotherapy. A total 25 with who were pathologically confirmed stage II-III underwent DCE-MRI prior chemoradiotherapy, and at 3 weeks post-treatment, parameters [Ktrans (volume transfer constant; rate which contrast agent distributes from plasma EES), Kep (rate...
Abstract Functional neuroimaging studies have revealed abnormal brain dynamics of male sexual arousal (SA) in psychogenic erectile dysfunction (pED). However, the neuroanatomical correlates pED are still unclear. In this work, we obtained cortical thickness (CTh) measurements from structural magnetic resonance images 40 patients and 39 healthy control subjects. Abnormalities CTh related to were explored using a scale space search based morphometric analysis. Organizations covariance networks...
The present study investigated changes in the regional cerebral metabolic rates of glucose uptake (rCMRglc) using 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) and homogeneity (ReHo), together with resting-state blood oxygen level-dependent (BOLD) functional magnetic resonance imaging (fMRI), patients major depressive disorder (MDD). In total, 18 untreated MDD 17 healthy control subjects underwent 18F-FDG PET BOLD-fMRI scanning. patients' changes, measured as rCMRglc...
The aim of this study was to explore the functions cerebral blood perfusion and glucose metabolism in prefrontal lobe patients with major depression disorder (MDD), analyze correlations between these functional changes depressive symptoms. 3D‑arterial spin labeling (ASL) 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) were successfully performed 17 MDD 16 healthy controls a resting state. symptoms classified into seven factors scored Hamilton Depression...
