[Inflammatory gastrointestinal diseases in children : Radiological diagnosis].

Background/clinical Issue: Inflammatory bowel diseases are frequently seen in the clinical routine of a pediatric radiologist. The timely diagnosis of inflammatory bowel diseases in children is particularly important in acute cases.

Standard Radiological Methods/methodological Innovations: This nonsystematic article intends to give an overview of the radiologic imaging methods for the diagnosis and work-up of pediatric patients with inflammatory bowel diseases.

Performance: Ultrasound imaging is an important basis tool in pediatric clinical practice. However, sensitivity and specificity depends on the experience of the operator. Cross-sectional imaging modalities in pediatric patients with inflammatory bowel disease are performed only in exceptional cases when clinically justified. Dedicated computed tomography (CT) protocols for children are indispensable to lower radiation dose.

Achievements: Knowledge about particularities in inflammatory bowel diseases in pediatric patients and a rational approach to the use of radiological investigations in order to prevent the harmful effects of ionizing radiation are indispensable in dedicated pediatric imaging departments.

Practical Recommendations: From a radiation-hygiene point of view, the clinical application of ultrasound imaging should be favored in the work-up of pediatric patients with inflammatory bowel diseases. Knowledge about advanced imaging procedures is essential particularly in imaging departments specialized in pediatric radiology.
