title: A pilot study on the application of FFE and SSh-TSE sequences in ocular MRI.
abstract: OBJECTIVE
  To preliminarily investigate the application value of rapid sequences FFE and SSh-TSE in ocular magnetic resonance imaging (MRI).
  
  
  METHODS
  Ocular MRI was performed in 18 subjects without ocular conditions,and demonstration of 15 delicate anatomic structures on two sequences in each subject was rated by three proficient physicians.
  
  
  RESULTS
  FFE sequence was comparatively advantageous in demonstrating delicate structures on ocular wall and ocular adnexa (P<0.001) over SSh-TSE; while SSh-TSE sequence better revealed the delicate anatomy within anterior chamber (P<0.001) and optic nerve sheath (P<0.05), with statistically significant differences compared with FFE.
  
  
  CONCLUSIONS
  Optimized FFE and SSh-TSE sequences are able to effectively eliminate the impact from motion artifact and thus result in desirable images with high spatial resolution. The application of high-resolution MR microscopic imaging technique has improved the ability to demonstrate delicate ocular structures.
