Find lesions, aid Dx — imaging you can trust

Lesion detect, Dx aid & report gen for imaging

U2-RadiMed: Find lesions, aid Dx, write reports — imaging you can trust

U2-RadiMed is Unisound’s medical imaging LLM for image+text input. It helps doctors read scans, locate lesions, aid Dx, and auto-generate structured reports — an end-to-end AI assistant from image analysis to clinical decision support.

Comprehensive Capability Evaluation

This evaluation covers the full capability stack from low-level perception (lesion detection and localization) to high-level reasoning (clinical decision-making and advanced medical reasoning). Eighteen sub-tasks span multimodal imaging modalities including CXR, CT, and MRI, providing a comprehensive view of model performance in real-world medical imaging scenarios.

Key strengths

Full imaging workflow

From scan reading, lesion locate, Dx aid to structured report gen — one-stop coverage of key radiology steps.

Multimodal & multi-image understanding

Supports single/multi-image + text input. Strong at multi-sequence and temporal comparison for follow-up and complex cases.

Lesion-level visual locate

Not just a conclusion — it locates abnormalities so doctors can lock on lesions faster and reduce misses.

Clinical reasoning & decision support

Combines imaging with medical knowledge for differential Dx, treatment eval, and medical Q&A.

Medical-grade safety

AI suggestion + doctor confirm, plus result checks, keep outputs trustworthy with clear responsibility.

Tech highlights

Multimodal input

Image (base64 / URL) + text instruction; single and multi-image input.

Long-context understanding

40,960-token context window for multi-image inputs and long instructions.

Structured output

Text output with bbox, Dx notes, and structured reports; supports locate results for visualization.

Use cases

Imaging report assist

Auto-draft structured reports with findings and impressions; doctors review and edit to cut paperwork.

Screening & lesion locate

Auto-marks suspected regions to help doctors lock on faster, cut misses, and shorten read time.

Follow-up & disease tracking

Compares pre/post-treatment and multi-sequence/temporal scans to track lesion change and treatment effect.

Difficult-case differential Dx

Combines imaging features with medical knowledge to list support/exclude evidence and probability for complex cases.

Capabilities

Lesion detect & locate

Detect abnormal lesions and output location (bbox); supports single-image and multi-image sequences.

Clinical reasoning

Reason over imaging + medical knowledge for disease tracking, multimodal differential Dx, and multimodal reports.

Clinical decision

Decision support on top of image understanding: sequence reading, multimodal treatment suggestions, and visual Q&A.

Report gen

Auto-generate diagnostic report text from images, including structured CXR and other imaging reports.

Flexible pricing, custom solutions, private deployment
