The purpose of this study was to evaluate the influence
of vibration frequency and imaging plane on stiffness
measurements in renal magnetic resonance elastography
(MRE). Coronal 90-Hz and 60-Hz, sagittal 90-Hz and axial
90-Hz MRE sequences of the kidneys were performed in 12
patients on a 1.5-T MRI. The MRE measured renal
stiffness on different vibration frequencies (90-Hz
versus 60-Hz) and different imaging planes (coronal
versus sagittal oblique versus axial projection)
were compared to determine the influence of these
variables. A significant difference in renal stiffness
was found between frequencies (p = 0.003) and between
imaging planes (p < 0.001).
