Multicenter reproducibility study of diffusion MRI and fiber tractography of the lumbosacral nerves.

ABSTRACT:

Background

Diffusion tensor imaging (DTI) has been applied in the lumbar and sacral nerves in vivo, but information about the reproducibility of this method is needed before DTI can be used reliably in clinical practice across centers.

Purpose

In this multicenter study the reproducibility of DTI of the lumbosacral nerves in healthy volunteers was investigated.

Study type

Prospective control series.

Subjects

Twenty healthy subjects.

Field strength/sequence

3T MRI. 3D turbo spin echo, and 3.0 mm isotropic DTI scan.

Assessment

The DTI scan was performed three times (twice in the same session, intrascan reproducibility, and once after an hour, interscan reproducibility). At site 2, 1 week later, the protocol was repeated (interweek reproducibility). F
