Synopsis

Keywords: Myocardium, Software Tools

Motivation: Cardiac diffusion tensor imaging (cDTI) can estimate several biomarkers of myocardial remodeling. We evaluated an open-source software package for cDTI processing to enable robust data processing and promote rigorous science.

Goal(s): The goal of this study was to evaluate the open-source Cardiac Diffusion in Python (CarDpy) toolbox and identify which post-processing step (POST) most impact improved tensor metric quality.

Approach: CarDpy was evaluated at six POSTs. cDTI metrics and their corresponding uncertainties were measured across slices and assessed for significance.

Results: cDTI metrics and corresponding uncertainties displayed minimal improvements beyond shot-rejection.

Impact: CarDpy is an open-source cardiac diffusion data processing toolbox that enables community development and promotes rigorous science. Each post-processing step was evaluated to estimate the impact on improving the quality of several tensor metrics.
