Three dimensional Fourier transformation constructive; interference in
steady state (3DFT-CISS) magnetic resonance imaging (MRI) allows a de
tailed visualization of the membranous labyrinth of the inner ear. In
this study the endolymphatic duct and sac is investigated in patients
with Meniere's disease using 3DFT-CISS MRI. In addition, the distance
between the vertical part of the posterior semicircular canal and the
fossa posterior is quantified.
