CG-SENSE revisited: Results from the first ISMRM reproducibility challenge.

ABSTRACT:

Purpose

The aim of this work is to shed light on the issue of reproducibility in MR image reconstruction in the context of a challenge. Participants had to recreate the results of "Advances in sensitivity encoding with arbitrary k-space trajectories" by Pruessmann et al. METHODS: The task of the challenge was to reconstruct radially acquired multicoil k-space data (brain/heart) following the method in the original paper, reproducing its key figures. Results were compared to consolidated reference implementations created after the challenge, accounting for the two most common programming languages used in the submissions (Matlab/Python).

Results

Visually, differences between submissions were small. Pixel-wise differences originated from image orientation, assumed field-of-vie
