On the accuracy and precision of PLANET for multiparametric MRI using phase-cycled bSSFP imaging.

ABSTRACT:

Purpose

In this work we demonstrate how sequence parameter settings influence the accuracy and precision in T₁ , T₂ , and off-resonance maps obtained with the PLANET method for a single-component signal model. In addition, the performance of the method for the particular case of a two-component relaxation model for white matter tissue was assessed.

Methods

Numerical simulations were performed to investigate the influence of sequence parameter settings on the accuracy and precision in the estimated parameters for a single-component model, as well as for a two-component white matter model. Phantom and in vivo experiments were performed for validation. In addition, the effects of Gibbs ringing were investigated.
