Report Supervision

Read the original on arXiv Computer Vision →

The paper introduces Report Supervision (R‑Super), a framework that uses radiology reports to supervise tumor segmentation models. By incorporating loss functions that align segmentation outputs with report‑derived tumor counts, sizes, and locations, R‑Super improves detection and segmentation performance. Experiments on kidney and pancreatic tumors show up to a 15% increase in F1‑Score and DSC compared to mask‑only training, outperforming methods like CLIP and multi‑task learning.

Merlin Plus: A Large-Scale, Multi-Cancer, Image-Mask-Report Dataset

Merlin Plus is a new, large-scale CT dataset that provides radiologist‑created tumor masks for nine different organs, adding 1,153 per‑voxel masks and longitudinal metadata to the existing Merlin collection. The dataset was built using a report‑based active‑learning framework, where radiology reports flag tumor cases, a segmentation model generates initial masks, and radiologists review and correct them, thereby reducing annotation effort while preserving high quality. The added longitudinal data enables temporal modeling of cancer progression, supporting scalable multi‑organ cancer detection, segmentation, and longitudinal analysis in CT.

Colorectal Cancer Segmentation with Adaptive Augmentation and Multi-Resolution Ensemble Models

The paper presents an automated segmentation pipeline for whole‑slide histopathology images of colorectal cancer, labeling tumor grades 1‑3 and normal mucosa. It employs dense prediction transformers with multiple encoder backbones, overlapping patches, test‑time augmentation, and an adaptive augmentation policy guided by large language models. The approach, combined with soft‑voting ensembles and post‑processing refinements, raises the F1 score from 62.92 to 69.84 on a colorectal cancer grade dataset.
