Performance of externally validated machine learning models based on histopathology images for the diagnosis, classification, prognosis, or treatment outcome prediction in female breast cancer: A systematic review

no code implementations9 Dec 2023 Ricardo Gonzalez, Peyman Nejat, Ashirbani Saha, Clinton J. V. Campbell, Andrew P. Norgan, Cynthia Lokker

The aim of this systematic review was to assess the performance of externally validated ML models based on histopathology images for diagnosis, classification, prognosis, or treatment outcome prediction in female breast cancer.

Seeing the random forest through the decision trees. Supporting learning health systems from histopathology with machine learning models: Challenges and opportunities

no code implementations6 Dec 2023 Ricardo Gonzalez, Ashirbani Saha, Clinton J. V. Campbell, Peyman Nejat, Cynthia Lokker, Andrew P. Norgan

This paper discusses some overlooked challenges faced when working with machine learning models for histopathology and presents a novel opportunity to support "Learning Health Systems" with them.

Machine learning applications using diffusion tensor imaging of human brain: A PubMed literature review

no code implementations18 Dec 2020 Ashirbani Saha, Pantea Fadaiefard, Jessica E. Rabski, Alireza Sadeghian, Michael D. Cusimano

We performed a PubMed search to find 148 papers published between January 2010 and December 2019 related to human brain, Diffusion Tensor Imaging (DTI), and Machine Learning (ML).

Detection of masses and architectural distortions in digital breast tomosynthesis: a publicly available dataset of 5,060 patients and a deep learning model

1 code implementation13 Nov 2020 Mateusz Buda, Ashirbani Saha, Ruth Walsh, Sujata Ghate, Nianyi Li, Albert Święcicki, Joseph Y. Lo, Maciej A. Mazurowski

While breast cancer screening has been one of the most studied medical imaging applications of artificial intelligence, the development and evaluation of the algorithms are hindered due to the lack of well-annotated large-scale publicly available datasets.

Automatic deep learning-based normalization of breast dynamic contrast-enhanced magnetic resonance images

no code implementations5 Jul 2018 Jun Zhang, Ashirbani Saha, Brian J. Soher, Maciej A. Mazurowski

Then, based on the segmentation results, a subject-specific piecewise linear mapping function was applied between the anchor points to normalize the same type of tissue in different patients into the same intensity ranges.

Deep learning in radiology: an overview of the concepts and a survey of the state of the art

no code implementations10 Feb 2018 Maciej A. Mazurowski, Mateusz Buda, Ashirbani Saha, Mustafa R. Bashir

In this article, we review the clinical reality of radiology and discuss the opportunities for application of deep learning algorithms.

Deep Learning for identifying radiogenomic associations in breast cancer

no code implementations29 Nov 2017 Zhe Zhu, Ehab AlBadawy, Ashirbani Saha, Jun Zhang, Michael R. Harowicz, Maciej A. Mazurowski

Results: The best AUC performance for distinguishing molecular subtypes was 0. 65 (95% CI:[0. 57, 0. 71]) and was achieved by the off-the-shelf deep features approach.

Deep learning analysis of breast MRIs for prediction of occult invasive disease in ductal carcinoma in situ

no code implementations28 Nov 2017 Zhe Zhu, Michael Harowicz, Jun Zhang, Ashirbani Saha, Lars J. Grimm, E. Shelley Hwang, Maciej A. Mazurowski

In the first approach, we adopted the transfer learning strategy, in which a network pre-trained on a large dataset of natural images is fine-tuned with our DCIS images.

Full-reference image quality assessment by combining global and local distortion measures

no code implementations17 Dec 2014 Ashirbani Saha, Q. M. Jonathan Wu

Therefore, we hypothesize that the resulting objective score for an image can be derived from the combination of local and global distortion measures calculated from the reference and test images.
