Cognita

What Cognita does

Cognita is a healthcare AI company building generative vision-language models that interpret medical imaging studies in clinical context and produce preliminary reports for radiologist review. Founded in October 2024 by a Stanford-rooted team led by CEO Louis Blankemeier alongside CTO Zhihong Chen and co-founder Akshay Chaudhari, the company focuses initially on radiology because the specialty is already deeply digitized and faces a documented global workforce shortage. Its flagship product, Cognita Chest X-ray (Cognita CXR), is a generative vision-language model that processes chest X-ray images and outputs structured preliminary reports covering demographics, clinical history, prior studies, positive findings, comparisons, and measurements. Internal clinical validation cited by the company showed enhanced detection rates of 16% to 65% for certain significant findings and a potential 18% improvement in interpretation efficiency among participating radiologists. In 2026, Cognita CXR became the first generative vision-language model for radiography to receive FDA Breakthrough Device designation, a development-stage regulatory status that enables prioritized FDA interactions but is not yet a clearance.

The company's business model centers on enterprise B2B deployment of its AI tools directly into radiology workflows within health systems and large radiology practices. Less than a year after founding, Cognita was acquired by Radiology Partners, the world's largest radiology practice, and now operates as the AI business unit of Mosaic Clinical Technologies, a wholly-owned subsidiary of Radiology Partners. This embedded structure gives Cognita access to one of the world's largest real-world radiology datasets for training and validation, continuous human feedback loops from practicing radiologists, clinical infrastructure, and a built-in distribution channel across Radiology Partners' health system footprint. The company is concurrently building an enterprise field sales capability to pursue direct relationships with health systems and hospitals beyond the parent network. Cognita is headquartered in the San Francisco Bay Area, operates as an in-person team of 1-10 employees, and has not disclosed external pricing or external venture funding.

Core offering

Cognita develops generative vision-language AI models that interpret radiology imaging studies in clinical context and generate draft preliminary reports for radiologist review. Its flagship product, Cognita Chest X-ray (Cognita CXR), reads chest X-rays the way a radiologist would, producing comprehensive findings for clinician sign-off. The company operates as the AI business unit of Radiology Partners, the world's largest radiology practice.

Product overview

Cognita is building healthcare AI, starting with radiology. The company operates as the AI business unit of Mosaic Clinical Technologies (a wholly-owned subsidiary of Radiology Partners). Cognita's primary product is Cognita Chest X-ray (Cognita CXR), a generative vision-language model for chest X-ray interpretation. This model processes X-ray images and generates comprehensive preliminary text reports to support radiologists in clinical decision-making. The company is currently focused on expanding radiology access through AI-assisted diagnosis.

Direct peers

• Qure.ai: Qure.ai develops deep-learning models for radiology interpretation across X-ray, CT, and head CT, with strong global deployment including LMICs. It directly competes in AI-generated radiology findings and reporting.
• DeepHealth: DeepHealth is RadNet's AI subsidiary focused on breast and prostate cancer imaging, with broader radiology AI ambitions. As a competitor also backed by a large imaging-services parent, it parallels Cognita's Radiology Partners ownership structure.
• Aidoc: Aidoc develops AI-powered clinical decision support for radiology, including triage and detection of acute findings in CT, with broad enterprise deployments. It directly competes with Cognita in AI-driven radiology workflow augmentation.
• Annalise.ai: Annalise.ai builds comprehensive AI for radiology reporting across multiple modalities and findings, similar to Cognita's vision-language approach to generating preliminary reports from imaging studies.
• Viz.ai: Viz.ai builds AI for radiology workflows, most notably for stroke detection and care coordination. It directly competes with Cognita on AI-assisted radiology interpretation and integrated clinical workflows.
• RapidAI: RapidAI offers AI for neuroimaging and stroke care coordination, focusing on CT and MRI interpretation. It competes with Cognita in AI-driven radiology workflow enhancement for acute care.

Emerging players

• HeartFlow: HeartFlow applies AI to cardiac CT to non-invasively assess coronary artery disease. It is comparable to Cognita as a modality-specialized AI for radiology reporting, but focused specifically on cardiology.

Broad incumbents

• RadNet: RadNet is one of the largest outpatient imaging center operators in the US and has built its own AI capability through DeepHealth. It overlaps with Cognita on AI for radiology workflows at scale, though from a services-platform perspective.
• Tempus AI: Tempus AI (which acquired Arterys) combines imaging AI with broader clinical data. It is comparable to Cognita in applying AI to medical imaging interpretation but operates as a broad data-driven precision medicine platform.
• Zebra Medical Vision: Zebra Medical Vision (now part of Nanox) provides broad radiology AI algorithms across multiple modalities and findings. It is comparable to Cognita as an enterprise radiology AI platform with multiple indications.
