Modeling Vascular Branching Alterations in Polycystic Kidney Disease

no code implementations20 Dec 2022 Timothy L. Kline

For instance, in polycystic kidney disease (PKD), drastic cyst development may lead to a significant alteration of the vascular geometry (or vascular changes may be a preceding event).

Quantifying and Visualizing Vascular Branching Geometry with Micro-CT: Normalization of Intra- and Inter-Specimen Variations

no code implementations20 Dec 2022 Timothy L. Kline

Micro-CT images of the renal arteries of intact rat kidneys, which had their vasculature injected with the contrast agent polymer Microfil, were characterized.

Shape Aware Automatic Region-of-Interest Subdivisions

no code implementations17 Dec 2022 Timothy L. Kline

The resulting subdivisions can therefore either not relate well to the actual shape or property of the region being studied (i. e., gridding methods), or be time consuming and based on user subjectivity (i. e., manual methods).

Reproducibility in medical image radiomic studies: contribution of dynamic histogram binning

no code implementations9 Nov 2022 Darryl E. Wright, Cole Cook, Jason Klug, Panagiotis Korfiatis, Timothy L. Kline

The de facto standard of dynamic histogram binning for radiomic feature extraction leads to an elevated sensitivity to fluctuations in annotated regions.

Best Practices and Scoring System on Reviewing A.I. based Medical Imaging Papers: Part 1 Classification

no code implementations3 Feb 2022 Timothy L. Kline, Felipe Kitamura, Ian Pan, Amine M. Korchi, Neil Tenenholtz, Linda Moy, Judy Wawira Gichoya, Igor Santos, Steven Blumer, Misha Ysabel Hwang, Kim-Ann Git, Abishek Shroff, Elad Walach, George Shih, Steve Langer

The goal of this series is to provide resources to not only help improve the review process for A. I.-based medical imaging papers, but to facilitate a standard for the information that is presented within all components of the research study.
