• Authors: Robin Y. Park, Rhydian Windsor, Amir Jamaludin, Andrew Zisserman,
• Abstract summary: We propose a pipeline to automate the extraction of labels from radiology reports using large language models. Our method equals or surpasses GPT-4 on a held-out set of reports. We show that the extracted labels can be used to train imaging models to classify the identified conditions in the accompanying MR scans.

• Abstract: We propose a general pipeline to automate the extraction of labels from radiology reports using large language models, which we validate on spinal MRI reports. The efficacy of our labelling method is measured on five distinct conditions: spinal cancer, stenosis, spondylolisthesis, cauda equina compression and herniation. Using open-source models, our method equals or surpasses GPT-4 on a held-out set of reports. Furthermore, we show that the extracted labels can be used to train imaging models to classify the identified conditions in the accompanying MR scans. All classifiers trained using automated labels achieve comparable performance to models trained using scans manually annotated by clinicians.
