Advancing Radiograph Representation Learning with Masked Record Modeling

Zhou, Hong-Yu, Lian, Chenyu, Wang, Liansheng et al.

Understand

Modern studies in radiograph representation learning rely on either self-supervision to encode invariant semantics or associated radiology reports to incorporate medical expertise, while the complementarity between them is barely noticed.

  • To explore this, we formulate the self- and report-completion as two complementary objectives and present a unified framework based on masked record modeling (MRM).
  • In practice, MRM reconstructs masked image patches and masked report tokens following a multi-task scheme to learn knowledge-enhanced semantic representations.
  • With MRM pre-training, we obtain pre-trained models that can be well transferred to various radiography tasks.
