ROCOv2: Radiology Objects in COntext Version 2, an Updated Multimodal Image Dataset

Understand

Automated medical image analysis systems often require large amounts of training data with high quality labels, which are difficult and time consuming to generate.

• This paper introduces Radiology Object in COntext version 2 (ROCOv2), a multimodal dataset consisting of radiological images and associated medical concepts and captions extracted from the PMC Open Access subset.
• It is an updated version of the ROCO dataset published in 2018, and adds 35,705 new images added to PMC since 2018.
• It further provides manually curated concepts for imaging modalities with additional anatomical and directional concepts for X-rays.
