[Congenital diaphragmatic hernia : Imaging-from diagnosis to aftercare]. / Kongenitale Zwerchfellhernie : Bildgebung von der Diagnose bis zur Nachsorge.

STANDARD RADIOLOGICAL METHODS: Fetal: Ultrasound and magnetic resonance imaging (MRI); postnatal: conventional X­ray diagnostics, computed tomography (CT) and MRI. METHODICAL INNOVATIONS: MRI-based lung ventilation and perfusion measurement. PRACTICAL RECOMMENDATIONS: Lifelong follow-up care should be provided, in which radiology is part of the treatment team.

[Septic arthritis and transient synovitis of the hip]. / Septische Arthritis und Coxitis fugax.

CLINICAL/METHODICAL ISSUE: Differentiating between septic arthritis and transient synovitis can be challenging but is very important as a late diagnosis of septic arthritis can lead to sepsis and joint damage. For correct diagnosis and prediction of complications, the right combination of physical examination, laboratory and radiological studies is needed. STANDARD RADIOLOGICAL METHODS: Hip ultrasound is easy to learn and has a high sensitivity for joint effusion. Faster diagnosis and therapy are possible due to increasing use of ultrasound. Magnetic resonance imaging (MRI) is primarily used to rule out co-infections (osteomyelitis, pyomyositis) and differential diagnoses. X­ray is typically nonremarkable in septic arthritis. PRACTICAL RECOMMENDATIONS: Routine use of ultrasound in nontraumatic pediatric hip pain. Generous use of MRI in case of elevated inflammatory markers or inconclusive clinical findings. Using only few sequences may be appropriate to avoid sedation, primarily fluid sensitive sequences (fat-saturated T2, TIRM, STIR), in case of positive findings, accompanied by T1-weighted images.

[Sports injuries in children and adolescents]. / Sportverletzungen im Kindesalter.

CLINICAL/METHODOLOGICAL ISSUE: Due to active participation of children and adolescents in school sports as well as in club sports, sporting injuries in childhood are common. Because skeletal maturity is not yet complete, injury patterns in children differ from sporting injuries in adults. Knowledge of the pathophysiologic characteristics, as well as knowledge of typical injury sequelae, is of great relevance to radiologists. This review article therefore deals with common acute and chronic sporting injuries in children. STANDARD RADIOLOGICAL METHODS: Basic diagnostic imaging comprises conventional X­ray imaging in two planes. In addition, sonography, magnetic resonance imaging (MRI) and computed tomography (CT) are used. PRACTICAL RECOMMENDATIONS: Close consultation with clinical colleagues and knowledge of childhood-specific injuries help identify sports-associated trauma sequelae.
