LLM Explanations: Steps Matter in Radiology

Radiologists assigned to receive step-by-step explanations from a large language model achieved higher diagnostic accuracy in a randomized vignette study, while differential-diagnosis outputs may have increased inappropriate reliance on incorrect model suggestions.

A study published in npj Digital Medicine analyzed the diagnostic accuracy of 101 US radiologists across 20 radiology cases. Radiologists were divided into groups receiving varying levels of large language model (LLM) support, including chain-of-thought prompts that improved their accuracy by 12 percentage points over controls. The study found that while the chain-of-thought method increased the accuracy of diagnostic assessments significantly compared to standard and differential-diagnosis support, it raised concerns regarding reliance on incorrect model recommendations.
