There is controversy over discograms in the lumbar spine. However, it is little compared to the controversy in cervical or thoracic discs. The volume of the discs is so much lower, some believe that getting good discography results is impossible.
The difference between a well done discography and a poorly done one is dramatic. Also, the people who perform discography do not believe that is the definitive, be all, end all test. It is more data that is added to the evaluation. Greater weight is given to clear results. Less weight given to less clear results. The people who don't beleive in discography don't seem to understand that all is not black and white.
