Joint Learning of Localized Representations from Medical Images and Reports

Müller, Philip, Kaissis, Georgios, Zou, Congyu et al.

Understand

Contrastive learning has proven effective for pre-training image models on unlabeled data with promising results for tasks such as medical image classification.

  • Using paired text (like radiological reports) during pre-training improves the results even further.
  • Still, most existing methods target image classification downstream tasks and may not be optimal for localized tasks like semantic segmentation or object detection.
  • We therefore propose Localized representation learning from Vision and Text (LoVT), to our best knowledge, the first text-supervised pre-training method that targets localized medical imaging tasks.
