- Abstract summary: This study investigates the impact of improvements in radiology report labeling on the performance of chest X-ray classification models.
We compare the CheXpert, CheXbert, and VisualCheXbert labelers on the task of extracting accurate chest X-ray image labels from radiology reports.
We show that an image classification model trained on labels from the VisualCheXbert labeler outperforms image classification models trained on labels from the CheXpert and CheXbert labelers.

- Abstract: Although deep learning models for chest X-ray interpretation are commonly
trained on labels generated by automatic radiology report labelers, the impact
of improvements in report labeling on the performance of chest X-ray
classification models has not been systematically investigated. We first
compare the CheXpert, CheXbert, and VisualCheXbert labelers on the task of
extracting accurate chest X-ray image labels from radiology reports, reporting
that the VisualCheXbert labeler outperforms the CheXpert and CheXbert labelers.
Next, after training image classification models using labels generated from
the different radiology report labelers on one of the largest datasets of chest
X-rays, we show that an image classification model trained on labels from the
VisualCheXbert labeler outperforms image classification models trained on
labels from the CheXpert and CheXbert labelers. Our work suggests that recent
improvements in radiology report labeling can translate to the development of
higher performing chest X-ray classification models.

We present a benchmark study of the long-tailed learning problem in the specific domain of thorax diseases on chest X-rays.
We focus on learning from naturally distributed chest X-ray data, optimizing classification accuracy over not only the common "head" classes, but also the rare yet critical "tail" classes.
The benchmark consists of two chest X-ray datasets for 19- and 20-way thorax disease classification, containing classes with as many as 53,000 and as few as 7 labeled training images.

Classification [25.76256302330625]
New medical imaging classification problems may need to rely on machine-generated noisy labels extracted from radiology reports.
Current noisy-label learning methods designed for multi-class problems cannot be easily adapted.
We propose a new method designed for the noisy multi-label CXR learning, which detects and smoothly re-labels samples from the dataset.

We propose an end-to-end semi-supervised cross-modal contrastive learning framework for medical images.
We first apply an image encoder to classify the chest X-rays and to generate the image features.
The radiomic features are then passed through another dedicated encoder to act as the positive sample for the image features generated from the same chest X-ray.
