Comparison of conventional Spin-Echo and Fast Spin-Echo magnetic resonance imaging with fat suppression in crutiate ligament injury

AIM: To compare the quality and diagnostic reliability of conventional spin-echo and fast spin-echo with fat suppression magnetic resonance (MR) imaging in the evaluation of cruciate ligament injury. METHODS: Thirty-five patients with internal knee injury and positive clinical signs of cruciate ligament injury were examined by using an Elscint Prestige 2T MR scanner. Findings of conventional and fast spin-echo with fat suppression MR sequences were evaluated and compared with each other and with arthroscopic findings. In all patients, arthroscopy was performed within 2 months after the MR examination. RESULTS: Analysis of anterior cruciate ligament injury with conventional spin-echo sequence showed 81.8% sensitivity. The sensitivity of fast spin-echo sequences with fat suppression was 96.9%. According to the type of the anterior cruciate ligament injury, the sensitivity of fast spin-echo sequences with fat suppression was higher than that of conventional spin-echo sequence (85.7% and 66.7%, respectively) for partial rupture, but the sensitivity of both sequences for complete rupture was the same (100% both). CONCLUSION: Fast spin-echo with fat suppression sequence can be used routinely in clinical practice for the assessment of acutely injured knees as the substitute for conventional spin-echo sequence without decreased diagnostic reliability.
