BACKGROUND AND PURPOSE:Normative age-related decline in paravertebral muscle quality is important for reference to disease and risk identification in patients. We aimed to establish age-and vertebral level-dependence of paravertebral (multifidus and erector spinae) muscle volume and fat content in healthy adult volunteers.

IVIM parameters strongly depend upon the choice of the b-value threshold used for computation. The proposed algorithm may be used as a robust approach for IVIM analysis without organ-specific adaptation.
