headline: Microsoft AI Beats Doctors In Diagnosing Complex Medical Cases: Study
dek: Existing medical AI models typically take an all-at-once approach that examines all of a patient's symptoms, lab results and imaging studies to generate a diagnosis.

Microsoft researchers say an AI tool that diagnoses patients step by step, as doctors do, was more than twice as accurate as general physicians at solving complex medical cases, according to a study published on Thursday in Science.

quick_read: Microsoft researchers built a diagnostic AI that works through a case in stages instead of reviewing all symptoms, lab results and imaging at once. A study published in Science reports that it outperformed general physicians on complex cases.

If the result holds up, step-by-step reasoning could be a better design for medical AI than the all-at-once approach used by existing models. The supplied excerpt is cut off, so details of the test cases, the physician comparison and real-world use are not available.

key_points: Existing medical AI models typically examine a patient's symptoms, lab results and imaging studies all at once to generate a diagnosis. | The Microsoft tool instead diagnoses patients step by step, mirroring how doctors work. | The researchers say it was more than twice as accurate as general physicians on complex cases. | The findings were published on a Thursday in the journal Science.
rundown: The article contrasts two designs for medical AI. Current models take an all-at-once approach, while the Microsoft system works through a patient's case sequentially.

Microsoft researchers report that this sequential approach made the tool more than twice as accurate as general physicians on complex medical cases. The comparison is reported through the Science study.

The excerpt ends mid-sentence as it begins describing what the model identified, so specific results, case numbers and any clinical deployment plans are not in the supplied text.
