Stability analysis of dynamic radiomics features for cardiac magnetic resonance

Introduction

General workflow

Data sets

MRXCAT

Simulations with different SNR (5,10,20,30) using MRXCAT [1] version v1.4 and the breathhold phantom. Code is in code/mrxcat_simulations and simulation results in data/mrxcat_simulations. The simulations were performed with Matlab version R2021b. Simulation results have to be converted from the cpx format to the nifti format for further analysis. Steps include:

1. .cpx to .csv convertion
2. .csv to .nifti convertion The masks were then extracted from the breathhold phantom used for the simulation in MRXCAT.
