Non-radiologist-performed point-of-care ultrasonography in paediatrics — European Society of Paediatric Radiology position paper
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-19)Non-radiologist point-of-care ultrasonography (US) is increasingly implemented in paediatric care because it is believed to facilitate a timely diagnosis, such as in ascites or dilated renal pelvicalyceal systems, and can be used to guide interventional procedures. To date, all policy statements have been published by non-radiologic societies. The European Society of Paediatric Radiology hereby ... -

A novel magnetic resonance imaging scoring system for active and chronic changes in children and adolescents with juvenile idiopathic arthritis of the hip
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-23)Abstract Background Hip involvement predicts severe disease in juvenile idiopathic arthritis (JIA) and is accurately assessed by MRI. However, a child-specifc hip MRI scoring system has not been validated.<p> <p>Objective To test the intra- and interobserver agreement of several MRI markers for active and chronic hip changes in children and young adults with JIA and to examine the precision of ... -

Secondly, to compare cone-beam computed tomography (CBCT) and magnetic resonance imaging (MRI) in the measurement of condylar height.<p> <p>Methods: Those included were children diagnosed with JIA during 2015–18 who had had ... -
Oral health-related quality of life in 4-16-year-olds with and without juvenile idiopathic arthritis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-06)Background: Few studies have investigated oral health-related quality of life (OHRQoL) in young individuals with juvenile idiopathic arthritis (JIA). Aims were to investigate whether OHRQoL difers between children and adolescents with JIA compared to controls without JIA, while adjusting for socio-demographic-, behavioral- and oral healthrelated covariates. Furthermore, to explore whether socio-behavioral ... -
Pediatric whole-body magnetic resonance imaging: comparison of STIR and T2 Dixon sequences in the detection and grading of high signal bone marrow changes
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-26)Objectives To compare short time inversion recovery (STIR) and T2 Dixon in the detection and grading of high signal intensity areas in bone marrow on whole-body MRI in healthy children. <p><p>Methods Prospective study, including whole-body 1.5-T MRIs from 77 healthy children. Two experienced radiologists in consensus identifed and graded areas of high bone marrow signal on STIR and T2-weighted (T2W) ... -
Prevalence of temporomandibular disorder in children and adolescents with juvenile idiopathic arthritis – a Norwegian cross- sectional multicentre study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-13)<i>Background</i> - Children and adolescents with juvenile idiopathic arthritis (JIA) may suffer pain from temporomandibular disorder (TMD). Still, routines for the assessment of temporomandibular joint (TMJ) pain in health and dental care are lacking. The aims of this study were to examine the prevalence of TMD in children and adolescents with JIA compared to their healthy peers and to investigate ... -
Radiographic markers of hip dysplasia in young adults: predictive effect of factors in early life
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-11)Background and objectives Acetabular dysplasia in young adults occurs, despite screening for developmental hip dysplasia (DDH) in the neonatal period. We aimed to examine how early life factors predict radiographic measurements of acetabular dysplasia at 18–19 years of age.<p> <p>Methods From a previous randomized trial (n=12,014; 1988–90) evaluating the role of hip ultrasound in newborn screening ... -
References for ultrasound staging of breast maturation, tanner breast staging, pubic hair, and menarche in Norwegian girls
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-06)<i>Context</i> - Discriminating adipose and glandular tissue is challenging when clinically assessing breast development. Ultrasound facilitates staging of pubertal breast maturation (US B), but has not been systematically compared to Tanner breast (Tanner B) staging, and no normative data have been reported.<p> <p><i>Objective</i> - To present normative references for US B along with references ... -
Revisiting the radiographic assessment of osteoporosis-Osteopenia in children 0-2 years of age. A systematic review
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-02)<i>Background</i> - Imaging for osteoporosis has two major aims, first, to identify the presence of low bone mass (osteopenia), and second, to quantify bone mass using semiquantitative (conventional radiography) or quantitative (densitometry) methods. In young children, densitometry is hampered by the lack of reference values, and high-quality radiographs still play a role although the evaluation ... -
