    "description": "An MRI of the lumbar spine - the low back - run twice in one sitting: first plain, then again after contrast dye is injected into a vein. Comparing the two sets of images helps separate scar tissue from a genuinely recurrent disc problem, and makes infection or tumor light up clearly. This is the most thorough of the three low-back MRI options, which otherwise cover plain-only or dye-only studies.",
