Overview

Methinks CTA Stroke is an artificial intelligence (AI)-based software solution designed to accurately detect suspected large vessel occlusions (LVOs) using Computed Tomography Angiography (CTA) scans. This FDA 510(k) cleared device (K251590) is a radiological computer-aided triage and notification tool intended for use by hospital networks and trained clinicians. It analyzes CTA images to identify suspected LVOs, including both proximal (MCA-M1, ICA) and more distal occlusions (MCA-M2 segment), with high sensitivity (98.2%) and specificity (91.6%). The software integrates seamlessly into hospital systems like PACS and Microsoft Teams, enabling real-time collaboration, instant AI alerts, and secure communication among stroke teams. By providing rapid and reliable LVO prediction, Methinks CTA Stroke aims to optimize stroke triage, accelerate treatment decisions, and improve patient outcomes, particularly in time-sensitive emergencies. It complements Methinks’ NCCT Stroke software, offering a comprehensive stroke triage platform compatible with both non-contrast CT and CTA imaging, adaptable to various healthcare settings from advanced stroke centers to low-resource clinics.

What Physicians Need to Know

Stroke Detection Speed
Provides an average time to notification of one minute and 27 seconds. The solution aims to reduce door-to-decision times and avoid treatment delays, potentially saving up to 40 minutes in CTA acquisition by enabling direct transfer to the angiosuite for endovascular treatment.
Brain MRI/CT Analysis
Analyzes Non-Contrast Computed Tomography (NCCT) and Computed Tomography Angiography (CTA) images of the head. It detects Large Vessel Occlusions (LVO) and Intracranial Hemorrhages (ICH) on NCCT scans. For CTA, it detects LVOs, including distal occlusions up to the middle cerebral artery (MCA)-M2 segment. The tool also assesses ischemic core volume on NCCT.

Large Vessel Occlusion Detection
A core capability, detecting LVOs from both NCCT and CTA images. For NCCT, it has demonstrated 75% sensitivity and 83% specificity in one study, and 76.4% sensitivity and 91.1% specificity in another context. For CTA, it achieved 98.2% sensitivity and 91.6% specificity in validation testing, identifying proximal (ICA, MCA-M1) and distal (MCA-M2) LVOs. It can also detect posterior vessel occlusions.
Triage Prioritization Speed
Functions as a radiological computer-aided triage and notification system, designed to assist physicians by notifying them of suspected positive cases of ICH and LVO in emergency settings. It aims to optimize stroke triage, reduce time to treatment, and facilitate early transfers of high-probability LVO patients.
ASPECTS Score Automation
The Methinks Ischemia algorithm for NCCT can estimate ischemic core volume, which is strongly associated with clinical outcomes and can predict favorable outcomes even in patients with a favorable ASPECTS score. In late-window patients, the estimation of ischemic core volume on NCCT with Methinks Ischemia algorithm appears to be superior to CTP and ASPECTS.
Mobile Notification System
Provides instant AI alerts with results to clinicians when on call. It integrates seamlessly with Microsoft Teams, allowing for real-time collaboration, secure team messaging, and image sharing without requiring additional software.
Physician Tip

Leverage Methinks CTA Stroke's rapid LVO and ICH detection capabilities on both NCCT and CTA to significantly accelerate stroke triage and treatment decisions. Utilize the integrated mobile notification system for immediate alerts and streamlined team coordination, especially in time-sensitive stroke cases. Integrate AI findings with your clinical assessment to optimize patient pathways, particularly in settings with limited access to advanced imaging. The tool's ability to identify LVOs and hemorrhages is crucial for determining patient eligibility for thrombolysis or endovascular treatment, potentially improving patient outcomes.

Methinks CTA Stroke offers seamless integration with existing hospital Picture Archiving and Communication Systems (PACS) and hospital information systems. It is deeply integrated with Microsoft Teams, providing a platform for real-time alerts, secure communication, image review, and team collaboration. The solution is available through the Microsoft Azure Marketplace for secure installation and payment. Additionally, Methinks AI has a strategic partnership with Medtronic, aiming to integrate its AI solutions into Medtronic's stroke treatment ecosystem to enhance care coordination.
