![]() ![]() There is a definite need for a well-structured clinical network to seek for further technical progress, to offer a profound education and training program, to test the usefulness of ultrasound in new fields, to implement it in clinical trials and to foster the application of sonography in daily practice. Beside “traditional” vascular neurology, currently new fields of application such as muscle and nerve imaging, orbital ultrasound and online monitoring techniques in intensive care are booming. Neurosonology is an outstanding diagnostic instrument in the hand of clinical neurologists with unique selling points such as specific imaging technology, high spatial resolution, online observation, noninvasiveness as well as broad and easy availability in the clinical routine all over Europe. The Executive Committee of the ESNCH has decided during the annual meeting in Berlin 2017 to joiand to support this initiative. This network is designed as a reference network, which works in close cooperation with the European Society of Neurosonology and Cerebral Hemodynamics ). You can also use a tegaderm patch over the eye to make a barrier for scanning.During the meeting of the EAN Scientific Panel of Neurosonology in Copenhagen 2016, it was decided to establish a Network of European Reference Centers in Neurosonology (ERNSono). Use a small amount of sterile gel rubbing it onto the transducer face to make a thin film. ![]() In this window you will be able to scan the OA. These arteries join to form the posterior cerebral arteries. The flow will be below baseline for both. In the occipital or trans-forminal window you will encounter the bilateral Vertebral arteries and singular Basilar artery. In the temporal window angling down you will be able to insonate the terminal ICA MCA – Above baseline (typically highest in velocity) ACA – Below baseline PCA – Bi-directional (lowest in velocity of the 3 vessels) Occipital/Trans-Foraminal Using a zero degree angle and a moderate sized gate. In the temporal window you will scan the MCA, ACA and PCA advancing 2mm from distal to proximal in the MCA. The technique involves using several windows. It is made up of the ACA, PCA, Posterior communicating (PcomA) Artery and Anterior communicating Artery (AcomA). Named eponymously after Thomas Willis, the Circle of Willis is an anastomotic vascular ring at the base of the brain. ![]() Once the ICA enters the brain it gives off the Opthalmic artery, Posterior communicating artery and Terminates in the Anterior and Middle cerebral artery bifurcation.
