To explore the feasibility of applying quantitative magnetic resonance imaging techniques for the diagnosis of children with attention-deficit/hyperactivity disorder (ADHD) comorbid autistic traits (ATs). A prospective study was performed by selecting 56 children aged 4-5 years with ADHD-ATs as the study group and 53 sex- and age-matched children with ADHD without ATs as the control group. All chi...

Background To standardize renal functional magnetic resonance imaging (MRI), it is important to understand the influence of side to side variation, regional variation within the organ, and hydration states in MRI and to search for variables that are not affected by those variations. Purpose To assess MRI based biomarkers for characterizing the kidney in healthy volunteers while considering variat...

To explore the application of quantitative magnetic resonance imaging in the diagnosis of autism in children. Sixty autistic children aged 2-3 years and 60 age- and sex-matched healthy children participated in the study. All the children were scanned using head MRI conventional sequences, 3D-T1, diffusion kurtosis imaging (DKI), enhanced T2*- weighted magnetic resonance angiography (ESWAN) and 3D-...

Inserting diffusion weighted imaging (DWI) into the time interval between post contrast and hepatobiliary phase (HBP) is time saving and health economic friendly. However, whether DWI would be affected before and after Gd-EOB-DTPA is still unknown. This study aims to validate whether the DWI at both low and high b-values is affected before and after Gd-EOB-DTPA enhancement. From July 2019 to Novem...

This study aimed to explore the ability of radiomics derived from both MRI and 18F-fluorodeoxyglucose positron emission tomography (18F-FDG-PET) images to differentiate glioblastoma (GBM) from solitary brain metastases (SBM) and to investigate the combined application of multiple models. The imaging data of 100 patients with brain tumours (50 GBMs and 50 SBMs) were retrospectively analysed. Three ...

Early detection and diagnosis of hepatocellular carcinoma (HCC) is essential for prognosis; however, the imaging hallmarks for tumor detection and diagnosis has remained the same for years despite the use of many new immerging imaging methods. This study aimed to evaluate the detection performance of hepatic nodules in high risk patients using either hepatobiliary specific contrast (HBSC) agent or...

To explore the application of three-dimensional pseudocontinuous arterial spin labeling (3D-PCASL) perfusion imaging in the brains of children with autism and to understand the characteristics of cerebral blood perfusion in children with autism. A total of 320 children with autism (160 men and 160 women) aged between 2 and 18 years and 320 age- and sex-matched healthy children participated in the ...

This study found that the decreased iron content in some brain regions of children with ADHD. This study found that the globus pallidus, caudate nucleus, hippocampus, and putamen could distinguish children with ADHD (AUC > 0.5, p .05). The volume of frontal lobe and hippocampus of children with ADHD was lower than that of healthy children (p 0.5, p < .05). Quantitative susceptibility mapping showe...

Internal carotid artery dissection (ICAD) is the major cause of ischemic stroke in young to middle-aged people. Recognition of predisposing factors may facilitate in early individual risk prediction and expand treatment. To evaluate the association between a carotid web and dissection in patients with ICAD using vessel wall magnetic resonance imaging (VW-MRI). A retrospective study was conducted o...

Objective To evaluate the value of synthetic magnetic resonance imaging (syMRI), diffusion weighted imaging (DWI), DCE MRI, and clinical features in breast imaging–reporting and data system (BI RADS) 4 lesions, and develop an efficient method to help patients avoid unnecessary biopsy. Method A total of 75 patients with breast diseases classified as BI RADS 4 (45 with malignant lesions and 30 with...
