[Value of ultrasound diagnosis in pediatrics].
Due to its easy applicability, lack of invasiveness, and high yield of information, ultrasound performed by the experienced examiner has become an indispensable diagnostic tool in many areas of clinical pediatrics. This is reflected by the large numbers of ultrasound studies both in pediatric private practice and in children's hospitals. Therefore, quality standards and quality control are of paramount importance. For many clinical problems, ultrasound has led to new diagnostic and even therapeutic concepts. In the German-speaking countries, ultrasound has officially been established as a screening method for the hip, but in clinical practice also for other organ systems. Due to technological developments of the last few years, the diagnostic yield has significantly been improved, and new areas of application have been established.
