title: ESR position paper on ultrasound.
abstract: This paper re-emphasises the important role of diagnostic ultrasound. It underlines the importance of ultrasound as a non-invasive imaging procedure which does not use ionising radiation. The paper also illustrates how ultrasound is often the cornerstone of the work up of the patient and the need for radiology departments to be able to offer expert ultrasound on a 24/7 basis. Some aspects related to turf battles and education are discussed. Finally the way in which these issues will be addressed by the European Society of Radiology is outlined.
