How It Compares

Viz.ai vs Traditional Stroke Protocols

Traditional stroke protocols rely on radiologists manually reviewing CT scans and communicating findings to neurologists, who then contact interventionalists if thrombectomy is indicated. This sequential process takes 30-60 minutes or more, during which 1.9 million neurons die every minute in stroke patients. Viz.ai automates detection and parallelizes communication - the AI identifies the LVO within minutes of scan completion and simultaneously alerts the entire team, who can review imaging and prepare for intervention while the patient is still being evaluated. Studies show Viz.ai reduces door-to-treatment time by an average of 52 minutes compared to traditional protocols, translating to significantly improved patient outcomes. For every 15 minutes saved in stroke treatment, one additional patient per hundred achieves independent functional recovery. Viz.ai's automation also ensures consistent 24/7 performance regardless of radiologist availability or fatigue.

Viz.ai vs Other AI Stroke Detection

Several companies offer AI stroke detection, but Viz.ai distinguishes itself through comprehensive care coordination beyond just image analysis. Competitors may detect LVO but lack integrated communication workflows, leaving hospitals to manually notify teams. Viz.ai combines detection with intelligent alerting, mobile care coordination, treatment planning support, and analytics - a complete platform for time-critical emergency response. The 1,400+ hospital deployment demonstrates real-world adoption and trust from healthcare systems. FDA breakthrough device designation and extensive clinical validation provide regulatory and evidence advantages. Viz.ai's continuous expansion to multiple conditions (stroke, PE, aortic dissection) creates a unified platform for time-critical emergencies, while single-condition tools require separate systems. The mobile app's one-touch communication and comprehensive case presentation are particularly valued by clinicians managing emergencies.

Preguntas frecuentes

How does Viz.ai detect strokes?+

Viz.ai uses FDA-cleared deep learning algorithms to automatically analyze CT angiography (CTA) scans of the brain, identifying large vessel occlusions (LVO) - blockages in major brain arteries causing severe strokes. The AI was trained on hundreds of thousands of brain scans to recognize patterns of vessel occlusion invisible or time-consuming for humans to detect. When a CTA is performed in the emergency department, images are automatically sent to Viz.ai's cloud servers where algorithms analyze them within minutes. If an LVO is detected with high confidence, the system immediately alerts the stroke team through the mobile app. The algorithms specifically detect occlusions in the internal carotid artery, M1/M2 segments of the middle cerebral artery, and other large vessels - the locations where thrombectomy intervention provides maximum benefit.

How much does Viz.ai cost?+

Viz.ai uses enterprise pricing customized based on hospital size, patient volume, specific products deployed, and contract terms. Pricing typically involves annual subscription fees scaled to the number of CT scanners, emergency department volume, or patient encounters. Comprehensive stroke centers might pay $50,000-150,000+ annually depending on configuration and volume, though exact pricing varies significantly. The investment includes software licensing, mobile app access, cloud computing infrastructure, integration services, training, and ongoing support. Healthcare systems deploying multiple Viz products (stroke, PE, aortic dissection) receive bundled pricing. While substantial, hospitals justify the investment through improved patient outcomes, reduced morbidity/mortality, shorter lengths of stay, and enhanced competitive positioning for stroke care. Many contracts include value-based components tied to time-to-treatment improvements or outcome metrics. Contact Viz.ai directly for detailed pricing appropriate to your specific situation.

Does Viz.ai replace radiologists or neurologists?+

No, Viz.ai augments rather than replaces physicians. The platform accelerates detection and communication but requires physician confirmation and clinical decision-making. When Viz.ai detects a suspected LVO, it alerts the care team, but neurologists review the imaging and clinical presentation before making treatment decisions. Radiologists still provide official interpretations of imaging studies. What Viz.ai eliminates is the time lag between scan completion and specialist notification - instead of waiting for radiologist review, dictation, and communication to neurology, the AI provides immediate flagging allowing parallel workflows. This is particularly valuable after-hours when radiologist or neurologist immediately available. The platform also reduces false negatives - cases where subtle LVOs might be missed by radiologists scanning hundreds of studies. Viz.ai serves as a safety net and acceleration tool, ensuring time-critical cases receive immediate specialist attention while physicians maintain diagnostic authority and treatment decisions.

What are Viz.ai's false positive and false negative rates?+

Viz.ai's FDA clearance studies demonstrated over 90% sensitivity (correctly identifying true LVOs) with specificity around 70-80% (correctly identifying negatives). This means the algorithm catches the vast majority of actual LVOs but generates some false positives - cases flagged as suspicious that turn out not to be true occlusions upon physician review. The balance is intentionally weighted toward high sensitivity because missing a real stroke (false negative) has catastrophic consequences, while false positives only result in brief physician review time. In practice, stroke specialists quickly review flagged cases through the mobile app and dismiss false positives within minutes. The high sensitivity ensures very few true LVOs are missed, providing the safety net hospitals need for time-critical emergencies. False positive rates are acceptable given the alternative - manual review that's slower and subject to human error and fatigue. Continuous algorithm improvements are reducing false positives while maintaining excellent sensitivity.

How quickly does Viz.ai alert the stroke team?+

Viz.ai typically alerts the stroke team within 5-10 minutes of CT scan completion. The process includes: (1) automatic transmission of imaging from CT scanner to Viz.ai cloud, (2) AI analysis of the scan (1-2 minutes), (3) immediate mobile app notifications to all stroke team members simultaneously if LVO detected. This is dramatically faster than traditional workflows where radiologists manually review scans, dictate reports, and communicate findings to neurologists, which can take 30-60+ minutes. The parallel notification means interventionalists, neurologists, and emergency physicians all receive alerts simultaneously rather than sequentially, enabling team preparation while the patient is still undergoing initial assessment. The mobile app provides complete imaging access so specialists can review cases immediately from anywhere. This speed is critical given that stroke patients lose 1.9 million neurons per minute - every minute of delay worsens outcomes.

What conditions beyond stroke can Viz.ai detect?+

Beyond LVO stroke detection, Viz.ai has expanded to identify pulmonary embolism (blood clots in lung arteries) on chest CT scans and aortic dissection (tears in the aorta wall) on CT imaging. The pulmonary embolism module alerts appropriate specialists when high-risk PE is detected, enabling rapid anticoagulation or intervention. The aortic dissection detection flags this life-threatening emergency requiring immediate surgical consultation. Viz.ai continues expanding its portfolio to address additional time-critical conditions where rapid diagnosis and care coordination improve outcomes. The unified platform approach means hospitals can deploy multiple Viz modules through a single integrated system rather than separate point solutions. Future development focuses on other emergency conditions where AI detection and intelligent care coordination can reduce time-to-treatment for life-threatening diagnoses.
