Rapid ICH

Identifies Suspected Intracranial Hemorrhage in Minutes

Rapid ICH uses the latest artificial intelligence technology to quickly triage non-contrast CT (NCCT) cases and notify clinicians of possible intracranial hemorrhage (ICH). It helps stroke team members on the front lines of patient assessment streamline decision-making and expedite patient care.

Rapid ICH
Fast. Accurate. Efficient.

Clear Results to Help Save Lives

Rapid ICH automatically processes images and assesses them for hemorrhage—presenting clear, easy-to-read results that make it easier for physicians to make critical decisions faster.

Sensitivity of 95% and Specificity of 94%

Rapid ICH uses the latest in artificial intelligence to automatically identify all types of suspected hemorrhage with a sensitivity of 95% and specificity of 94%, excluding hemorrhagic transformations (HTs).

Results in a Fraction of the Time

Rapid ICH processes Rapid results in as few as 3 minutes from receipt of scan.

Identifies Suspected Hemorrhage Subtypes

Rapid ICH identifies suspected hemorrhage subtypes including intraparenchymal, intraventricular, subdural, and subarachnoid.

Faster Treatment and Triage Decisions

Rapid ICH can be used by hospitals and Mobile Stroke Units for quick patient triage and treatment decision-making.

Identifies Suspected Hemorrhages in All Regions

Rapid ICH notifies clinicians of suspected intracranial hemorrhages in all brain regions.

Fast, Automatic Results

Rapid ICH automatically sends results through PACS, email and the Rapid Mobile App. 


Optimized for Frontline Assessment, Rapid ICH is:

  • Fast. Rapid ICH identifies the presence (or absence) of suspected intracranial hemorrhage and sends results to stroke team members in 3 minutes or less.
  • Accurate. Leveraging intelligence gained from more than a thousand scans analyzed from hospitals and clinics around the world, Rapid ICH identifies all types of suspected hemorrhage with a sensitivity of 95% and specificity of 94%, excluding hemorrhagic transformations (HTs).
  • Efficient. Rapid ICH automatically sends notifications through PACS, email, and the Rapid Mobile App. Clinicians have the flexibility to specify the type of alerts they receive—positive only or all.

Suspected ICH Identification:
A Technical Overview of Rapid ICH and the Role of Machine Learning

RapidAI has developed a computerized system based on machine learning that automatically screens CT scans for the presence of intracranial hemorrhage (ICH) immediately after the scan acquisition. This technical paper highlights the importance of this development and the role of state-of-the-art AI systems— from methods and data to suspected ICH identification accuracy and performance.
