Several studies have reported that [[disc degeneration]] and signs of [[facet]] [[effusion]] detected on T2-weighted (T2W) MRI can be indicators of potential lumbar spine instability ((Kuhns BD, Kouk S, Buchanan C, Lubelski D, Alvin MD, Benzel EC, Mroz TE and Tozzi J: Sensitivity of magnetic resonance imaging in the diagnosis of mobile and nonmobile L4-L5 degenerative spondylolisthesis. Spine J. 15:1956–1962. 2015)) ((Cho IY, Park SY, Park JH, Suh SW and Lee SH: MRI findings of lumbar spine instability in degenerative spondylolisthesis. J Orthop Surg (Hong Kong). 25(2309499017718907)2017.)).
