- Abstract summary: Medical imaging reports distill the findings and observations of radiologists.
Large-scale use of this text-encoded information requires converting the unstructured text to a structured, semantic representation.
We explore the extraction and normalization of anatomical information in radiology reports that is associated with radiological findings.

- Abstract: Medical imaging is critical to the diagnosis and treatment of numerous
medical problems, including many forms of cancer. Medical imaging reports
distill the findings and observations of radiologists, creating an unstructured
textual representation of unstructured medical images. Large-scale use of this
text-encoded information requires converting the unstructured text to a
structured, semantic representation. We explore the extraction and
normalization of anatomical information in radiology reports that is associated
with radiological findings. We investigate this extraction and normalization
task using a span-based relation extraction model that jointly extracts
entities and relations using BERT. This work examines the factors that
influence extraction and normalization performance, including the body
part/organ system, frequency of occurrence, span length, and span diversity. It
discusses approaches for improving performance and creating high-quality
semantic representations of radiological phenomena.

Generation [47.250147322130545]
Image-to-text radiology report generation aims to automatically produce radiology reports that describe the findings in medical images.
Most existing methods focus solely on the image data, disregarding the other patient information accessible to radiologists.
We present a novel multi-modal deep neural network framework for generating chest X-rays reports by integrating structured patient data, such as vital signs and symptoms, alongside unstructured clinical notes.

Collaborative Knowledge [6.792487817626456]
The cognitive task of interpreting medical images remains the most critical and often time-consuming step in the radiology workflow.
This work focuses on reducing the workload of radiologists who spend most of their time either writing or narrating the Findings.
Unlike past research, which addresses radiology report generation as a single-step image captioning task, we have further taken into consideration the complexity of interpreting CXR images.

We propose a novel anatomy-enhanced multimodal model to promote impression generation.
In detail, we first construct a set of rules to extract anatomies and put these prompts into each sentence to highlight anatomy characteristics.
We utilize a contrastive learning module to align these two representations at the overall level and use a co-attention to fuse them at the sentence level.
