WebFE X-rays are taken with the patient bedning forward or extending backward as far as possible while in the standing position. This allows for a better idea of how the spine looks in a functional position. This type of X-ray is called a dynamic radiograph. Dynamic F/E X-rays may be taken to look for spinal instability. WebSep 1, 2014 · However, with the advent of modern imaging techniques, namely magnetic resonance imaging (MRI), the use of dynamic radiographs (flexion/extension) has become underutilized in the clinical setting. In a recent article by Rhin et al., the presence of facet fluid (FF) on T2-weighted MRI had a positive predictive value (PPV) of 82% for …
