Emergency Medicine Neurology Radiology

Overview

Nico.Lab B.V.’s HALO is an AI-powered, cloud-based clinical support tool designed for rapid analysis of CT angiograms of the brain. It identifies imaging patterns suggestive of intracranial large vessel occlusion (LVO) and intracerebral hemorrhage (ICH) in patients suspected of stroke. HALO functions as a notification-only system, alerting medical specialists such as neurologists, radiologists, and emergency department physicians to suspected findings in parallel to the standard of care workflow. It is not a physician directory tool, but rather a diagnostic aid to facilitate timely evaluation and improve stroke care outcomes. HALO’s output is intended to support, not replace, primary diagnosis or clinical decisions by medical specialists. It is part of Nico.Lab’s broader StrokeViewer platform.

What Physicians Need to Know

Stroke Detection Speed
AI algorithms analyze CT and MRI scans to identify signs of ischemic or hemorrhagic stroke with remarkable speed and accuracy, crucial for time-sensitive treatments like thrombolysis and EVT. Nicolab's platform, StrokeViewer, detects and visualizes critical imaging findings within minutes.
Brain MRI/CT Analysis
AI algorithms enhance the interpretation of neuroimaging for stroke patients by analyzing CT and MRI scans to identify signs of ischemic or hemorrhagic stroke. StrokeViewer is an image processing application that analyzes CT and MR perfusion scans to indicate areas of the brain with suspected anterior circulation large vessel occlusion (LVO) or hemorrhagic stroke. It also performs calculations to quantify collateral circulation, brain perfusion, hemorrhagic stroke volume, and ASPECTS. Nicolab's platform offers perfusion analysis for both MR and CT images, providing insights into blood flow and brain tissue viability. The CT Perfusion module, integrated within StrokeViewer, provides advanced perfusion maps to help clinicians evaluate brain tissue viability and make informed treatment decisions.
EEG Interpretation AI
The provided information does not contain details about EEG Interpretation AI for Nicolab's HALO product. Other AI models like SCORE-AI have achieved human expert-level performance in fully automated interpretation of routine EEGs. These models can distinguish abnormal from normal recordings and classify abnormal EEGs into categories relevant for clinical decision-making. Such hybrid AI systems offer scalable and accurate solutions for EEG interpretation, assisting neurologists in improving diagnostic accuracy and reducing misdiagnosis rates.
Seizure Detection
The provided information does not contain details about Seizure Detection for Nicolab's HALO product.
Neurodegenerative Disease Screening
The provided information does not contain details about Neurodegenerative Disease Screening specifically for Nicolab's HALO product. However, other 'HALO' branded products are mentioned in the context of Alzheimer's therapeutics and early dementia detection.
Large Vessel Occlusion Detection
Nicolab's StrokeViewer LVO Triaging algorithm identifies image characteristics associated with a large vessel occlusion (LVO) and automatically alerts stroke teams. It has a sensitivity of 91.3% and specificity of 85.9% for occlusion detection. A retrospective study highlighted the potential of StrokeViewer in large vessel occlusion detection, showing promising results for integration into stroke care. In a study at NHS Lothian, StrokeViewer demonstrated high accuracy in detecting large vessel occlusions, with 93% sensitivity and 94% specificity.
Triage Prioritization Speed
AI-powered solutions enable swifter communication and collaboration among stroke care teams, facilitating rapid and informed decision-making. These tools expedite the evaluation and treatment process, minimizing the interval between patient arrival and treatment commencement. Nicolab's technology has been shown to reduce time from hospital arrival to treatment, resulting in 28% more Mechanical Thrombectomies performed in early window transfer patients in Australia and Europe. The platform aims to improve patient outcomes by optimizing the stroke workflow.
ASPECTS Score Automation
StrokeViewer performs calculations to quantify ASPECTS. The platform provides automated ASPECTS scoring. Automated scoring tools for non-contrast head CT can reduce inter-reader variability in thrombectomy and thrombolysis decisions. The ASPECTS Calculator is a decision-support tool that helps structure communication and provides a standardized 10-point stroke imaging score.
Mobile Notification System
The HALO app provides push notifications for consumer alerts and engagement. StrokeViewer, Nicolab's AI solution, enables rapid notification and image review from any device. Radiologists receive mobile notifications after AI analysis of patient scans. Physicians can review scans by logging into the system through a workstation or mobile phone. The StrokeViewer app is available via mobile or tablet. Critical patient information can be shared instantly with the stroke network to streamline patient transfers. Users can access results seamlessly through their mobile device, email, or PACS. The app is user-friendly and secure, ensuring consistent device experience.
Physician Tip

Nicolab's StrokeViewer, an AI-driven, cloud-based platform, significantly enhances stroke care by providing rapid and accurate analysis of CT and MRI scans for ischemic or hemorrhagic stroke. The platform's LVO Triaging algorithm and CT Perfusion module are FDA-cleared, offering high sensitivity and specificity for detecting large vessel occlusions and assessing brain tissue viability. The mobile notification system and DICOM viewer allow for quick access to critical information and AI-processed images on the go, facilitating faster decision-making and improved communication among stroke teams. This can lead to reduced time to treatment and better patient outcomes. While the platform excels in stroke diagnosis and workflow optimization, information regarding EEG interpretation, seizure detection, and neurodegenerative disease screening for this specific product is not available in the provided data.

Nicolab's StrokeViewer is designed for seamless integration into existing healthcare workflows, supporting both MR and CT perfusion imaging without requiring hospitals to change their current processes. It integrates with systems hospitals already use, providing longitudinal trends, alert history, and adaptive baselines. The platform offers HL7 v2 and FHIR R4 integration with EHRs, configurable per contract, and supports SSO via SAML or OIDC. It also allows for secure storage and aggregation of test results for telehealth solutions and outbreak monitoring. The system enables sharing of critical patient information and images across stroke networks, with HIPAA-compliant chat and screen-sharing features. Nicolab partners with various organizations, including Royal Philips, to solve critical bottlenecks in stroke treatment and optimize stroke workflows. The platform is cloud-based, allowing for remote configuration and updates.
