MRIs are great for understanding static compression (an obvious picture of a nerve compressed by a bone spur or herniation). However, the MRI is not as good for understanding dynamic compression. That is, compression that occurs from gravity and activity. The MRI is obviously performed by the patient lying down which negates the effects of gravity. This is where history, the physical examination and standing stress X-rays (flexion/extension) come into play.
If there is an angulation of one segment (two vertebra and the disc) on the AP X-ray (front to back), you have pain with standing and walking (history) and upon physical examination, extension (bending backwards) along with rotation to the painful side causes the leg pain, you most likely have foraminal stenosis or foraminal collapse (see website).
