What it is

This MRI of the lumbar spine takes one set of pictures without contrast dye and a second set after the dye is injected into a vein. The dye helps tell scar tissue from a new disc problem after back surgery and can show infection, inflammation or tumors.

What the price covers

The hospital price usually covers both sets of images; the contrast agent may appear as a separate line on some bills. The radiologist's reading is often billed separately.
