Abstract
Iterative least-squares MR reconstructions typically use the Conjugate Gradient algorithm, despite known numerical issues. This paper demonstrates that the more recent LSMR algorithm has favourable numerical properties, and is to be preferred in situations where Toeplitz embedding cannot be used to accelerate the Conjugate Gradient method.
