Evaluating diagnostic content of AI-generated radiology reports of chest X-rays

作者:

Highlights:

• Conventional quality metrics for natural language processing methods like the popular BLEU score, provide little information about the quality of the diagnostic content of AI-generated radiology reports.

• BLEU scores of generated reports can be high while they lack diagnostically important information.

• We investigate this problem and propose a new measure that quantifies the diagnostic content of AI-generated radiology reports.

• In addition, we exploit the standardization of reports by generating a sequence of sentences because in practice most of the radiologist use a well focused vocabulary of ‘standard’ sentences.
