[Radiological evaluation of acute abdomen in children].

CLINICAL/METHODICAL ISSUE: Acute, non-traumatic abdominal pain is one of the main reasons for medical consultation in pediatric patients. Knowledge of different diseases and their age dependence is essential for correct diagnosis and treatment.

STANDARD RADIOLOGICAL METHODS: Ultrasonography is the imaging method of choice. X‑ray is only used in case of emergency, e. g., suspected perforation.

METHODICAL INNOVATIONS: Contrast-enhanced ultrasonography (CEUS) and elastography complement ultrasonography.

PERFORMANCE: Magnetic resonance imaging is of increasing relevance for differential diagnosis of unclear sonographic results.

PRACTICAL RECOMMENDATIONS: The primary imaging modality in pediatric patients is ultrasonography. Cross-sectional imaging should only be used in cases of unclear sonographic findings.
