1.5-T MR imaging of organic laryngotracheal stenosis in a pediatric cohort predominantly younger than 7 years: protocol optimization and diagnostic performance.

Objective: To develop a 1.5-T MR imaging protocol tailored for organic laryngotracheal stenosis (LTS) and to assess its performance in visualizing anatomy and pathologies.

Materials And Methods: Presurgical laryngotracheal 1.

Research on the anti-oxidant and anti-aging effects of saponins in .

Oxidative stress and its impact on aging are critical areas of research. Natural anti-oxidants, such as saponins found in , hold promise as potential clinical interventions against aging. In this study, we utilized the nematode model organism, , to investigate the pharmacological effects of saponins (PKS) on antioxidation and anti-aging.

Prediction of the Labrum Shape in Patients With Developmental Dysplasia of the Hip Based on Pelvic Radiography.

Background: The shape of the labrum is strongly correlated with outcomes of developmental dysplasia of the hip (DDH). Magnetic resonance imaging (MRI) is the generally preferred imaging technique for observing the labrum.

Purpose: We aimed to find a correlation between the labrum shape and anterior-posterior (AP) pelvic measurements in children with DDH.

Observer- and radiomics model-based computed tomography classification of suppurative versus tuberculous lymphadenitis complicated with nodal necrosis of the neck in children.

Background: Computed tomography (CT) can be used for the early detection of lymphadenitis. Radiomics is able to identify a large amount of hidden information from images. However, few CT-based radiomics studies on cervical lymphadenitis in children have been published.

Brain MRI imaging markers associated with death in children with central nervous system involvement of hemophagocytic lymphohistiocytosis.

Objectives: To investigate the association of brain MRI and clinical variables with death in children with central nervous system involvement of hemophagocytic lymphohistiocytosis (CNS-HLH).

Methods: Clinical and brain MRI data of children with CNS-HLH from January 2012 to March 2022 were reviewed retrospectively. Patients were divided into the deceased group and the surviving group.

Magnetic resonance-enhanced high-resolution three-dimensional water-selective cartilage sequence visualization of hip vessels in children.

Purpose: Hip vessel examination provides key information on many hip-related pediatric diseases, and it has an important role in the evaluation of femoral head (FH) blood supply and diagnosis of avascular necrosis (AVN). The aim of this study was to investigate the feasibility of MR-enhanced high-resolution three-dimensional water-selective cartilage (3D-WATSc) sequence in visualizing the vessels of the hip joint in children.

Patients And Methods: Children with hip disease were randomly enrolled prospectively at our hospital from January 2021 to August 2022.

The diagnostic value of intravoxel incoherent motion imaging in differentiating high-grade from low-grade gliomas: a systematic review and meta-analysis.

Objective: This meta-analysis was carried out for assessing the accuracy of intravoxel incoherent motion (IVIM) parameters true diffusion coefficient (D), pseudo-diffusion coefficient (D*), and perfusion fraction (f) in differentiating low-grade gliomas (LGGs) from high-grade gliomas (HGGs).

Methods: Literatures concerning IVIM in the grading of brain gliomas published prior to October 20, 2020, searched in the Embase, PubMed, and Cochrane library. Use the quality assessment of diagnostic accuracy studies 2 (QUADAS 2) to evaluate the quality of studies.

Soft tissue calcifications secondary to Hymenoptera stings: a potential prognostic CT imaging sign in pediatric patients.

Context: Soft tissue calcifications (STCs) were incidentally found in some of the Hymenoptera-stung (HS) children when they underwent computed tomography (CT) scans for evaluating complications of vital organs. Afterwards, a predilection of STCs to the children with severe complications was clinically noticed. A hypothesis was then developed that STCs secondary to HS may correlate with poor outcomes.
