BoneBert: A BERT-based Automated Information Extraction System of Radiology Reports for Bone Fracture Detection and Diagnosis

Abstract: Radiologists make the diagnoses of bone fractures through examining X-ray radiographs and document them in radiology reports. Applying information extraction techniques on such radiology reports to retrieve the information of bone fracture diagnosis could yield a source of structured data for medical cohort studies, image labelling and decision support concerning bone fractures. In this study, we proposed an information extraction system of Bone X-ray radiology reports to retrieve the details of bone fracture … Show more

“…Biomedical ALBERT (BioALBERT) [ 52 ] is a context-dependent, rapid, and effective language model trained on huge biomedical corpora to overcome the problem of limited training data. BoneBert [ 53 ] is a BERT-based labeling system that was trained on a dataset of 6048 X-ray radiology reports and then fine-tuned using a small collection of 4890 expert annotations. Thus, by employing the pre-trained BERT model, features can be mapped into an embedding matrix that serves as input to other classifiers.…”

“…A review of data programming literature suggests that semi-supervised techniques might be a good fit for our problem space. Several existing pipelines combine a limited amount of training data, rulebased systems and neural models to achieve strong results on benchmark datasets (Maheshwari et al, 2020) and in various medical fields (Ling et al, 2019;Smit et al, 2020;Dai et al, 2021). By comparison, weak supervision-based data programming methods tend to focus on bootstrapping in the absence of data (Ratner et al, 2017(Ratner et al, , 2018, which is a nontrivial performance constraint.…”

“…A clinical version, ClinicalBERT, was later developed by pretraining the BERT model on EHR notes to achieve improved performance on clinical data [ 13 ]. Furthermore, the ClinicalBERT model has also been trained and validated for the extraction of radiological features from chest and bone x-ray notes [ 14 , 15 ].…”

“…The final NLP model, CheXbert, achieved state-of-the-art performance on one of the largest chest x-ray data sets, MIMIC-CXR, with an F 1 -score of 0.798, which is close to radiologists’ performances ( F 1 =0.805). Dai et al [ 15 ] took a similar approach using x-ray radiology reports for bone fracture. The authors developed a rule-based automatic labeling algorithm to label 6048 reports for model pretraining.…”
