Emerging evidence suggests a possible link between brown adipose tissue (BAT) and bone metabolism.The objective of this study was to examine the relationships BAT cross-sectional dimensions in children adolescents.This study.The conducted at pediatric referral center.Patients included 40 teenagers (21 males 19 females) successfully treated for malignancies.There were no interventions.The volume determined by fluorodeoxyglucose-positron emission tomography/computed tomography. Measures area...
Abstract Fetal magnetic resonance imaging (MRI) is an important adjunct modality for the evaluation of fetal abnormalities. Recently, low-field MRI systems at 0.55 Tesla have become available which can produce images on par with 1.5 but lower power deposition, acoustic noise, and artifact. In this article, we describe a technical innovation using to perform diagnostic quality MRI.
Abstract Objectives Exocrine pancreatic insufficiency (EPI) reflects inadequate enzyme(s) and/or bicarbonate secretion, leading to malabsorption. We aim compare different assessment tools for exocrine function and correlate them with the endoscopic test (ePFT) as a reference standard. Methods Combined retrospective prospective analysis of clinical data children who underwent clinically indicated ePFTs. compared ePFT against patient symptoms, laboratory results, magnetic resonance...
To determine the accuracy of plain abdominal radiographs in detection retained surgical needles varying size peritoneal cavity.Accidental retention foreign bodies cavity is estimated to occur once every 1000 1500 operations and early prevention identification increasingly important because mounting public awareness. Most existing literature on imaging has focused sponges, even though may account for up 50% such objects true not well established.Eight were obtained a 41 kg pig cadaver after...
Study Design. A cross-sectional comparison of vertebral morphology and lumbar lordosis (LL) in adolescents with without spondylolysis. Objective. To test the hypothesis that addition to LL, area (CSA) is also associated Summary Background Data. Recent data indicate CSA body a determinant which has been shown be Methods. Using magnetic resonance imaging, we compared degree LL from L1 L5 vertebrae 35 (16 females 19 males) spondylolysis 86 healthy controls (36 50 similar sex, age, height,...
Disruptions in perinatal care and support due to the COVID-19 pandemic was an unprecedented but significant stressor among pregnant women. Various neurostructural differences have been re-ported fetuses infants born during compared pre-pandemic counterparts. The relationship between maternal stress related disruptions fetal brain is yet unexamined.Pregnant participants with healthy pregnancies were prospectively recruited 2020-2022 greater Los Angeles Area. Participants completed multiple...
Various C1-2 instrumentation techniques have been developed to treat atlantoaxial instability. Screw fixation of poses a risk injury the vertebral artery and internal carotid (ICA). Injury ICA caused by C-1 screws is extremely rare, but has described. To characterize this risk, authors studied anatomical relationship lateral mass C-1.The 100 patients who had undergone computed tomography scanning magnetic resonance imaging neck assess position in association with mass. Each was classified...
The purpose of this study was to assess the repeatability water-fat MRI and diffusion-tensor imaging (DTI) as quantitative biomarkers pediatric lower extremity skeletal muscle.MRI at 3 T a randomly selected thigh leg seven healthy children studied using separation DTI techniques. Muscle-fat fraction, apparent diffusion coefficient (ADC), fractional anisotropy (FA) values were calculated. Test-retest interrater assessed by calculating Pearson correlation coefficient, intraclass Bland-Altman...
The buccal fat pad (BFP) is an encapsulated mass of adipose tissue thought to enhance the sucking capabilities masticatory muscles during infancy. To date, no conclusive evidence has been provided as composition BFP in early postnatal life.
Lumbar lordosis (LL) is more prominent in women than men, but the mechanisms responsible for this discrepancy are poorly defined. A recent study indicates that newborn girls have smaller vertebral cross-sectional area (CSA) when compared to boys—a difference persists throughout life and independent of body size. We determined relations between LL angle whether sex differences lumbar related CSA. Using multi-planar magnetic resonance imaging (MRI), we measured height spine 40 healthy boys...
ABSTRACT A small vertebral cross-sectional area (CSA) imparts a mechanical disadvantage that escalates the risk for fractures in elderly populations. We examined whether CSA is also associated with greater degree of wedging children. Measurements CSA, lumbar lordosis (LL) or thoracic scoliosis angle, and were obtained 100 healthy adolescents (50 boys 50 girls) 25 girls adolescent idiopathic (AIS) using magnetic resonance imaging. Vertebral vertebrae negatively correlated to posteroanterior...
