All patients were subjected to an MRI scan of the brain, and orbits were obtained with various conventional MRI sequences. All patients were subjected to an MRI scan using Philips
Ingenia 1.5 Tesla machine (The Netherlands). Various MRI sequences of orbits comprised of a combination of transverse and coronal images of orbits with 3 mm slice thickness using the following sequences:
Axial T2-weighted spin-echo sequence (TR/TE range: 3000/100–110 ms; flip angle: 90° matrix size: 230 × 240)
Axial T1-weighted spin-echo sequence (TR range/TE range, 450–600/11–13 ms; flip angle: 90°, matrix size: 150 × 140) without fat saturation.
Axial T2-weighted SPAIR (spectral attenuated inversion recovery) sequence (TR/TE range: 3000/90–100 ms; flip angle: 90°, matrix size: 280 × 260)
Coronal T2-weighted spin-echo sequence: TR/TE range: 6000/110–120 ms; flip angle: 90°, matrix size: 256 × 256)
