| Objective To investigate the methods of examination ,value of clinical application of meniscal magnetic resonance virtual endoscopy (MMRVE) for Stoller grade 3 meniscal tears. Methods 59 cases introduced fast spin echo (FSE)
sequences ,proton density imaging and T2 weighted imaging , 8 cases introduced T1 weighted imaging after knee joint
arthrography with contrast (Magenvist) injection. The workstation and software is GE AW and Navigator ,which was used
to become the row images to three-dimension virtual endoscopic imaging. Results MMRVE can reveal meniscal focal reversal ,strained of free edge ,surface erosion ,separated horn and broken horn. MMRVE can explain complex meniscal tears
(included bucket-handle tears) entirely ,those are difficult to reveal on traditional 2D MR imaging. The accuracy ,sensitivity
and specificity of MMRVE are 93 % ,96 % and 73 % respectively. It is quite useful to detect free bodies in amount and position. Conclusion It is a available and reliable means to diagnose meniscal tears using MMRVE. |
