Importance of High resolution MRI in Spine

So far fortunately i have worked in a set up where i have best of the best facilities. Two days back i had a patient who underwent an MRI for Lumbar spine with 0.2 T MRI. At first glance it appeared as if it is just a L5-S1 sequestered disc. But on close examination i could see that the fragment starts from upper border of L5 pedicle. Now, on saggital view i could not see the fragment to the best of its resolution. When i examined the axial cuts more closely i certainly could find that the fragment as such starts from lower border of L4-L5 disc space and down migrates upto L5-S1 disc's upper border. So all in all i want to state that for Spine MRI i would say the requirement should be atleast 0.5 T if you don;t have facility of 1.5T which is the best.
