Ultrasound diagnostics is now a widely used tool in patient care. It allows the clinical user to identify causes of disease quickly and directly. This didactically homogeneous standard work provides a comprehensive overview of the current state of vascular diagnostics of the brain-supplying arteries, including the associated clinical aspects. Techniques not relevant in everyday life have been deliberately omitted. The modular structure enables rapid orientation and ensures excellent handling. Beginners can easily become familiar with the systematics of Doppler and duplex sonography with the help of the methodological section. Experienced users can place their sonographic findings together with other imaging examinations in the clinical context of cerebrovascular diseases. Numerous case examples serve as practical learning aids. This book is a translation of an original German edition. The translation was done with the help of artificial intelligence(machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation.
