Magnetic Resonance Elastography of Intervertebral Discs: Spin-Echo Echo-Planar Imaging Sequence Validation.

ABSTRACT:

Background

Magnetic resonance elastography (MRE) is an imaging technique that can noninvasively assess the shear properties of the intervertebral disc (IVD). Unlike the standard gradient recalled echo (GRE) MRE technique, a spin-echo echo-planar imaging (SE-EPI) sequence has the potential to improve imaging efficiency and patient compliance.

Purpose

To validate the use of an SE-EPI sequence for MRE of the IVD compared against the standard GRE sequence.

Study type

Cross-over.

Subjects

Twenty-eight healthy volunteers (15 males and 13 females, age range: 19-55).

Field strength/sequence

3 T; GRE, SE-EPI with breath holds (SE-EPI-BH) and SE-EPI with free breathing (SE-EPI-FB) MRE sequences.

Assessment

MRE-derived shear stiffnesses were calculated via p
