Stroke Under the Probe: Advancing Diagnosis and Management with Ultrasound
Despite comprehensive workup, stroke etiology remains unknown in up to 30% of cases. A significant portion of these are classified as cryptogenic strokes, including the subset known as embolic stroke of undetermined source (ESUS), which might be even more prevalent in younger patients.
Made possible by the Canon Medical Academy, “Stroke Under the Probe: Advancing Diagnosis and Management with Ultrasound,” is an upcoming webinar taking place on September 4 at 7 pm (CEST), showcasing how neurosonology equips clinicians with real-time diagnostic insights – whether used independently, to define clinical thresholds, or to complement other imaging techniques.
Thanks to the portability and affordability of ultrasound systems, neurosonology can be readily integrated across a wide range of clinical environments (ER, stroke units, ICUs) and applied throughout all phases of stroke care, from acute assessment to long-term prevention.
This webinar is organized in collaboration with World Organization of Neurosonology (WON).

Presentation: Unmasking Undetermined Etiology in Stroke Using Advanced Ultrasound Techniques
In cryptogenic stroke, which accounts for at least 30% of ischemic strokes, especially in younger patients, the cause is not identified despite standard diagnostic testing. This can be due to incomplete diagnostic workup, multiple potential causes, or an underlying subtle/intermittent condition.
In Embolic Stroke of Undetermined Source (ESUS), a specific type of cryptogenic stroke, possible sources of emboli include paradoxical embolism, non-stenotic atherosclerotic plaques, and non-atherosclerotic cerebrovascular disease.
The identification of stroke etiology is vital in these patients because of the higher risk of recurrent stroke and treatment implications. Therefore, unmasking the undetermined etiology of stroke is pivotal for long-term prognosis and can be achieved with advanced cervical and intracranial vessel ultrasound imaging, transcranial ultrasound for accurate and noninvasive right-to-left shunt detection, and prolonged transcranial Doppler monitoring for microembolic signal interception.

Presentation: Acute Stroke Hemodynamic Assessment of Intracranial Vessels
Acute stroke requires rapid, accurate assessment of cerebral hemodynamics to guide timely intervention. Neurosonology, particularly transcranial ultrasound, offers a non-invasive, bedside method to evaluate intracranial vessel flow dynamics in real time. Bedside neurosonology enables the detection of arterial occlusions, stenosis, collateral flow patterns, and microembolic signals, contributing to diagnosis, monitoring, and direct therapeutic decision-making.
In the acute setting, dynamic cerebral blood flow assessment aids in modulating individualized patient management after reperfusion therapies, optimizing outcomes. Advancements in neurosonology enhance our understanding of cerebral hemodynamics in stroke pathophysiology, supporting its integration into comprehensive acute stroke protocols and neurovascular imaging strategies.
