A single mission unites every radiologist attending RSNA this year: advancing patient care through improved imaging technology. But as models grow more powerful and multimodal, their performance is only as strong as the data they learn from. The quality of annotation—not the quantity of images—has become the decisive factor in whether radiology AI succeeds or fails in real-world use.
Training and evaluating large language models (LLMs) for radiology isn’t just about labeling images; it’s about capturing nuanced patterns that mirror clinical reasoning. A model trained on inconsistent or poorly verified annotations can misclassify findings, miss subtle pathologies, or fail to generalize across patient populations. In radiology, where outcomes directly impact lives, there is no margin for approximation.
That’s why leading institutions and enterprises turn to Centaur.ai. Our platform combines collective intelligence with rigorous performance benchmarking to ensure every label reflects expert consensus. By comparing multiple annotator reads and rewarding accuracy through gamified quality control, Centaur delivers an unprecedented signal-to-noise ratio in radiology data.
Our results at Centaur.ai aren’t theoretical: they are proven. Our radiology labeling networks achieve results that rival top experts:
Centaur’s system is designed specifically for medical data. The platform supports DICOM radiology viewers, HIPAA and SOC 2 Type 2 compliance, and complex modalities including MRI, CT, ultrasound, and radiology text reports. With over 58,000 vetted medical professionals contributing millions of annotations weekly, Centaur empowers model developers to move from uncertainty to reproducible, evidence-backed performance.
Our research collaborations with major institutions have demonstrated that expert crowds can outperform individual experts in diagnostic accuracy. The result: data that reflects the collective intelligence of the field rather than the variability of a single reader.
At this year’s RSNA, Centaur.ai will be in Booth #5748, showcasing how collective intelligence transforms radiology model development. From fine-tuning LLMs for report summarization to generating benchmark datasets for multi-modal AI, attendees can see firsthand how Centaur’s annotation system elevates both model training and evaluation.
If your radiology AI pipeline depends on accurate ground truth, Centaur.ai is where quality becomes inevitable—not aspirational.
The Complete Guide to Medical AI Data Labeling in 2026 explains how high-quality annotation drives model accuracy, reliability, and deployment success in healthcare AI. Learn practical strategies for expert consensus, workflow design, and scalable data pipelines that reduce risk, control costs, and improve real-world performance in clinical and regulated environments.
