Automatic recognition of abdominal lymph nodes from clinical text

1 code implementation EMNLP (ClinicalNLP) 2020 Yifan Peng, SungWon Lee, Daniel C. Elton, Thomas Shen, Yu-Xing Tang, Qingyu Chen, Shuai Wang, Yingying Zhu, Ronald Summers, Zhiyong Lu

We then introduce an end-to-end approach based on the combination of rules and transformer-based methods to detect these abdominal lymph node mentions and classify their types from the MRI radiology reports.

Graph-Based Small Bowel Path Tracking with Cylindrical Constraints

no code implementations29 Jul 2022 Seung Yeon Shin, SungWon Lee, Ronald M. Summers

To circumvent this, a series of cylinders that are fitted along the course of the small bowel are used to guide the tracking to more reliable directions.

Universal Lymph Node Detection in T2 MRI using Neural Networks

no code implementations31 Mar 2022 Tejas Sudharshan Mathai, SungWon Lee, Thomas C. Shen, Zhiyong Lu, Ronald M. Summers

Results: Experiments on 122 test T2 MRI volumes revealed that VFNet achieved a 51. 1% mAP and 78. 7% recall at 4 false positives (FP) per volume, while the one-stage model ensemble achieved a mAP of 52. 3% and sensitivity of 78. 7% at 4FP.

Lymph Node Detection in T2 MRI with Transformers

no code implementations9 Nov 2021 Tejas Sudharshan Mathai, SungWon Lee, Daniel C. Elton, Thomas C. Shen, Yifan Peng, Zhiyong Lu, Ronald M. Summers

Identification of lymph nodes (LN) in T2 Magnetic Resonance Imaging (MRI) is an important step performed by radiologists during the assessment of lymphoproliferative diseases.

A Graph-theoretic Algorithm for Small Bowel Path Tracking in CT Scans

no code implementations1 Oct 2021 Seung Yeon Shin, SungWon Lee, Ronald M. Summers

It is formulated as finding the minimum cost path between given start and end nodes on a graph that is constructed based on the bowel wall detection.

Partial Identification and Inference for Conditional Distributions of Treatment Effects

no code implementations2 Aug 2021 SungWon Lee

This paper considers identification and inference for the distribution of treatment effects conditional on observable covariates.

Unsupervised Domain Adaptation for Small Bowel Segmentation using Disentangled Representation

no code implementations6 Jul 2021 Seung Yeon Shin, SungWon Lee, Ronald M. Summers

We present a novel unsupervised domain adaptation method for small bowel segmentation based on feature disentanglement.

Image Translation by Latent Union of Subspaces for Cross-Domain Plaque Detection

no code implementations22 May 2020 Yingying Zhu, Daniel C. Elton, SungWon Lee, Perry J. Pickhardt, Ronald M. Summers

In medical imaging applications, preserving small structures is important since these structures can carry information which is highly relevant for disease diagnosis.
