Radiology-Aware Model-Based Evaluation Metric for Report Generation

no code implementations28 Nov 2023 Amos Calamida, Farhad Nooralahzadeh, Morteza Rohanian, Koji Fujimoto, Mizuho Nishio, Michael Krauthammer

Furthermore, we demonstrate that one of our checkpoints exhibits a high correlation with human judgment, as assessed using the publicly available annotations of six board-certified radiologists, using a set of 200 reports.

Boosting Radiology Report Generation by Infusing Comparison Prior

no code implementations8 May 2023 Sanghwan Kim, Farhad Nooralahzadeh, Morteza Rohanian, Koji Fujimoto, Mizuho Nishio, Ryo Sakamoto, Fabio Rinaldi, Michael Krauthammer

To tackle this issue, we propose a novel approach that leverages a rule-based labeler to extract comparison prior information from radiology reports.

Unsupervised-learning-based method for chest MRI-CT transformation using structure constrained unsupervised generative attention networks

no code implementations16 Jun 2021 Hidetoshi Matsuo, Mizuho Nishio, Munenobu Nogami, Feibi Zeng, Takako Kurimoto, Sandeep Kaushik, Florian Wiesinger, Atsushi K Kono, Takamichi Murakami

The integrated positron emission tomography/magnetic resonance imaging (PET/MRI) scanner facilitates the simultaneous acquisition of metabolic information via PET and morphological information with high soft-tissue contrast using MRI.

Automatic classification between COVID-19 pneumonia, non-COVID-19 pneumonia, and the healthy on chest X-ray image: combination of data augmentation methods

1 code implementation1 Jun 2020 Mizuho Nishio, Shunjiro Noguchi, Hidetoshi Matsuo, Takamichi Murakami

Purpose: This study aimed to develop and validate computer-aided diagnosis (CXDx) system for classification between COVID-19 pneumonia, non-COVID-19 pneumonia, and the healthy on chest X-ray (CXR) images.

Automatic detection of acute ischemic stroke using non-contrast computed tomography and two-stage deep learning model

no code implementations9 Apr 2020 Mizuho Nishio, Sho Koyasu, Shunjiro Noguchi, Takao Kiguchi, Kanako Nakatsu, Thai Akasaka, Hiroki Yamada, Kyo Itoh

To assess the detection model's results, a board-certified radiologist also evaluated the test set head CT images with and without the aid of the detection model.

Lung segmentation on chest x-ray images in patients with severe abnormal findings using deep learning

no code implementations21 Aug 2019 Mizuho Nishio, Koji Fujimoto, Kaori Togashi

Results: Our results demonstrated that using baseline U-net yielded poorer lung segmentation results in our database than those in the JSRT and Montgomery databases, implying that robust segmentation of lungs may be difficult because of severe abnormalities.
