Intracranial Hemorrhage


Intracranial Hemorrhage can occur as a result of traumatic injury (falls, crashes etc…), ruptured arteries (aneurysms), stroke or cancer. It can result from injury within a vein or artery, or a combination of the two. Regardless of the cause, the timely and accurate diagnosis of active bleeding is essential to the successful care of these patients.

The Solution*

Zebra’s Intracranial Hemorrhage algorithm automatically detects suspected internal brain bleeds based on standard, non-contrast head CTs. This tool can provide early detection of people at high risk of severe brain bleeding events. The algorithm is comprised of a unique tailor-made neural network architecture designed to detect intracranial hemorrhage while tackling several challenges such as relatively small bleed size and high variance within the brain.

Customers with busy ED/ER environments, teleradiology, large academic centers and others use the Zebra Intracranial Hemorrhage triage solution as an alert for acute positive Intracranial Hemorrhage cases and attend those in a timely manner.

The Value

Intracranial hemorrhage has a high mortality rate – 40% at one month and 54% at one year. It is estimated that about 50% of this mortality occurs within the first 24 hours, emphasizing the importance of early detection.

Intracranial hemorrhage accounts for between 10% to 20% of all strokes. The financial impact of early detection would be enormous given the fact that stroke cost the U.S. alone $34 billion annually.

Zebra Triage solution allows robust integration into existing alert systems within the hospital, aiding ER physicians to be alerted promptly on acute cases such as Intracranial Hemorrhage. Our customers provide the highest quality standard of care, enhancing patient safety through prompt communication.

Using Zebra-Med’s solution, can save physicians more than 80% of the time to reach the acute condition.

“Over the past year UVA has been pleased to evaluate Zebra Medical Vision’s intracranial hemorrhage algorithm. The results were encouraging as the testing neuroradiologists saw value in accuracy and accessibility. Dr. Gaskin states, “Our early experience with AI insights on head CTs from Zebra is encouraging. We think the technology has the potential to both help identify and speed time to diagnosis.”
