Our
purpose is to compare 3D-FSE-Cube with 2D-FSE sequence for MR imaging of the
ankle at 3.0T MR system. Eight healthy volunteers were examined with 3D-FSE
Cube (6 minutes 50 seconds) and 2D-FSE (axial, sagittal and coronal planes,
total imaging time; 11minutes 24 seconds), and 3D-FSE-Cube images were
reformatted into images of same planes as 2D-FSE. Bone, cartilage, fluid, and
tendon SNRs and bone-tendon CNR were significantly higher with the
3D-FSE-Cube. The 3D-FSE-Cube sequence with parallel imaging at 3.0T MR
enables to reduce examination time preserving image quality and evaluate
complex anatomy of the ankle on multiple arbitrary planes.
