Spinal imaging: will MRI replace myelography?
A retrospective study on the value of magnetic resonance imaging (MRI) in replacing contrast studies of the lumbar spine has been undertaken. Studying pre- and postoperative conditions, the authors attempted to answer the question, Will MRI replace myelography? In this retrospective study, comparison is made in 20 patients between MRI and myelography and with 12 intra-operative findings. The overall impression was that MRI is equally sensitive as the invasive myelogram in diagnosing both protruded lumbar discs and postoperative fibrosis. The practical conclusion was an almost complete abandonment of myelography.
