Nodule analyser

Analyse a lung nodule

AI research tool: not a diagnosis. The result is an automated estimate of how suspicious a nodule looks, learned from radiologists' ratings. It can be wrong, and it cannot tell whether you have cancer. Please consult a doctor (such as a pulmonologist or oncologist) about any scan or symptom.

What to do next: whatever this estimate says, please discuss your scan with a doctor. They will compare it with earlier scans, your history and other tests. Many suspicious-looking nodules turn out to be harmless, and a low score does not rule out cancer.
