Methods and Materials
13 patients (7 male,
6 female,
mean age 42y,
range 21-76y) that were referred to our department for magnetic resonance imaging (MRI) evaluation of the ankle were enrolled.
All patients underwent MRI of the ankle using our standard 2D protocol (axial and paraxial T2w,
coronal and sagittal PDfs,
coronal and sagittal T1w; acquisition time: ~16:12) and the 3D-T2-SPACE-CS sequence in sagittal orientation with axial and coronal reconstruction (acquisition time: 04:34,
SL 0.6mm,
TE 92ms,
TR 1200ms,
FA 120°,
matrix 256x256,
FOV 160).
A dedicated ankle coil was used.
Patients were analyzed separately by 2 experienced radiologists: first with our standard 2D-protocol and after a waiting time of 6 weeks only with the 3D-T2-SPACE-CS sequence.
Visibilities of all ligaments as well as the relevant pathologic findings were documented for each protocol and patient.
Results were compared to each other.
