BACKGROUND Osteomyelitis can be difficult to diagnose and there has previously not been a prospective approach to identify all children in a defined geographic area. The aim of this study was to assess the annual incidence of osteomyelitis in children, describe the patient and disease characteristics in those with acute (< 14 days disease duration) and(More)
Lipoblastoma is a rare, benign soft-tissue tumour derived from embryonic fat. Four patients with tumours located in the upper limb are reported, with special reference to imaging techniques and histology. Radical surgical excision is essential to prevent local recurrence and exact imaging techniques are thus crucial. MRI appears to be a reliable(More)
The normal anatomy and many pathologies of the pediatric genitourinary system can be assessed with different imaging modalities. Most of them are based on the use of ionizing radiation and/or invasive techniques. The contribution of magnetic resonance imaging in this regard has opened new ways of approaching pathological conditions in this patient group.(More)
The purpose of this study was to assess the sensitivity, specificity, and diagnostic accuracy of magnetic resonance imaging (MRI) in pediatric patients with clinical suspicion of inflammatory bowel disease (IBD) by comparing MRI and ultrasound (US) to endoscopy, the gold standard. A median volume of 300 ml of mannitol in a 15% [corrected] watery solution(More)
BACKGROUND MRI is sensitive for joint inflammation, but its ability to separate subgroups of arthritis in children has been questioned. Infectious arthritis (IA), postinfectious arthritis (PA), transient arthritis (TA) and juvenile idiopathic arthritis (JIA) are subgroups that may need early, different treatment. OBJECTIVE To determine whether MRI(More)
BACKGROUND Examination of the paediatric urogenital tract is traditionally performed using methods that utilise ionising radiation, such as intravenous urography (IVU), computerised tomography (CT), voiding cystourethrography (VCU), and scintigraphy, in addition to ultrasound (US). OBJECTIVE To determine the potential and effectiveness of MR urography(More)
BACKGROUND The Norwegian Radiation Protection Authority recommends bismuth to protect radiosensitive surface organs during CT imaging. A study based on the use of phantoms was therefore initiated to investigate the usefulness of this protection on the breasts of young girls undergoing high-resolution computed tomography (HRCT) of the chest. MATERIAL AND(More)
Lipoblastoma is a rare, benign tumour of embryonal fat seen almost exclusively in infancy and early childhood. It occurs mostly in the extremities, but it is also seen in other parts of the body. The tumour may grow rapidly, and the fact that lipoblastomas show immature fat cells could lead to the wrong diagnosis of liposarcoma. Complete surgical excision(More)
