The purpose of this study was to evaluate the
reliability of a novel renal MRE (magnetic resonance
elastography) technique using spin-echo echo-planar
imaging (SE-EPI) in healthy volunteers. The study
population included 16 adult volunteers. Each
participant underwent two renal MRE examinations, within
a 30 minute interval between examinations. Two
radiologists acted as independent readers. The
test-retest repeatability and the inter-rater agreement
of the renal MRE technique were assessed using Bland
Altman, the within subject coefficient of variation, the
coefficient of repeatability, and interclass correlation
coefficient analysis. Our findings showed that SE-EPI
renal MRE is a reliable imaging technique.
