The clinical significance of cystic fluid motion in syringomyelia is uncertain. Because
of its sensitivity to fluid motion. MR imaging was used to investigate fluid dynamics in
syringomyelia by various techniques. SPAMM(Spatial Modulation of Magnetization) MRI
is one of these techniques which shows the fluid motion of syrinx in syringomyelia.
After taking preimaging pulse sequence, the MR images show periodic bands due to the
magnetic modulation. Motion between the time of banding and image formation is
directly demonstrated as a corresponding displacement of the bands. The authors
evaluated 7 patients of syringomyelia due to various causes with SPAMM MRI
technique and compared preoperative SPAMM MRI findings and clinical results,
postoperative size of syrinx. Among 4 patients of syringomyelia with Arnold-Chiari
malformation, 3 patients showed band shift representing fluid motion of syrinx on
SPAMM MRI. Clinical results of these patients were good and the size of postoperative
syrinx decreased. Three patients of posttraumatic or postmeningitic syringomyelia who
did not show band shift of SPAMM MRI had poor clinical courses and the sizes of
postoperative syrinx remained unchanged. These results indicate that SPAMM MRI may
be useful in determining the type of treatment and predicting clinical results in
syringomyelia.
