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...

We evaluated brain iron content in a healthy pediatric population using quantitative susceptibility mapping (QSM). From June 2018 to December 2019, healthy subjects aged 2-18 years old (200 males, 200 females) with no anatomical abnormalities were assessed. All of the children underwent 3D T1 anatomical MRIs in addition to the sequence scans of enhanced T2 star-weighted angiography (ESWAN). The ES...

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-...

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...

The oxidation or electroless nickel plating of SiC particles are two modification processes to improve the wettability of SiCp/Al interface. Studying the effects of this interface layer on compressive deformation of SiC particle reinforced aluminum matrix composites is helpful to optimising this compression process. In this paper, Deform-3D software was used to simulate the compression deformation...

To evaluate the application of adaptive statistical iterative reconstruction (ASIR) for chest CT scans of preschool-age children. Sixty children, ages 0 to < 1, 1 to < 3, and 3 to < 6 years, who underwent CT non-contrast-enhanced and enhanced scans were included. The non-contrast-enhanced scan sequences were performed with noise indexes (NIs) of 11, 14, and 16 for the 0 to < 1, 1 to < 3, and 3 to ...

Background Currently, there are many studies on the application of the 3D pseudocontinuous arterial spin-labeled (3D-pcASL) perfusion MRI technique for adult brain examinations, but few studies exist on the application of the technique for child brain examinations. Purpose To explore the application of a 3D-pcASL perfusion MRI scan combined with postlabeling delay (PLD) for assessing neonatal hyp...

PurposeTo investigate the feasibility of three dimensional pseudocontinuous arterial spin labeling (3D pcASL) perfusion imaging in the brain of children with Attention deficit/hyperactivity disorder (ADHD). Method A total of 78 ADHD children aged 5–13 years were prospectively selected as the study group, and 89 healthy children matched in age and sex were selected as the control group. All childre...
