TI  - MRI of the popliteofibular ligament: isotropic 3D WE-DESS versus coronal oblique 
      fat-suppressed T2W MRI.
PG  - 1141-6
AB  - OBJECTIVE: The objective was to compare isotropic 3D water excitation double-echo 
      steady state (WE-DESS) MRI with coronal oblique fat-suppressed T2-weighted (FS 
      T2W) images in the identification of the popliteofibular ligament (PFL). 
      MATERIALS AND METHODS: A prospective analysis of 122 consecutive knee MRIs was 
      performed in patients referred for knee pain from the orthopaedic clinic. In 
      addition to the standard knee sequences, isotropic WE-DESS volume acquisition 
      through the whole knee and coronal oblique FS T2W fast spin echo sequences 
      through the posterolateral corner were obtained. The presence of the popliteus 
      and biceps femoris tendons, lateral collateral and PFL was documented. Anterior 
      cruciate ligament injury was present in 33 cases and these were excluded from the 
      study because of the risk of associated PFL injury, leaving a total of 89 cases. 
      Of the 42 patients in whom arthroscopic evaluation was subsequently obtained, 
      none were found to have an injury to the PFL. RESULTS: The lateral collateral 
      ligament, biceps femoris and popliteus tendon were identified in all cases on all 
      sequences. The PFL was seen in 81 (91.0%; 95% CI 85.1-97.0%) patients using the 
      WE-DESS sequence and 63 (70.8%; 95% CI 61.3-80.2%) patients using the coronal 
      oblique FS T2W sequence, a statistically significant difference (p < 0.00005). 
      CONCLUSION: Isotropic 3D WE-DESS MRI significantly enhances our ability to 
      identify the popliteofibular ligament compared with coronal oblique 
      fat-suppressed T2-weighted images.
