Ultrasound is rapidly gaining ground in clinical medicine. This offers distinct advantages for diagnosis and treatment. This is notably the case when moving images are created by the treating physician, who can integrate them immediately with all other clinical information. The downside of a broad application of ultrasound is an increase in the number of incidental findings and missed diagnoses. This is amplified by the frequent lack of formal requirements for training and skills. Storage of ultrasound images may furthermore lead to verifiable misinterpretations. We are of the opinion that responsible integration of ultrasound in clinical practice requires clear peer agreements without sectarian thinking. To illustrate this, we discuss the dilemmas surrounding increased use of ultrasound from a medicolegal perspective.
