Remove ink stains. For ink stains, use hairspray or rubbing alcohol mixed with water. Spray the hairspray on the stain and blot carefully with a damp, clean cloth to avoid spreading the ink or letting it run on the upholstery.
The costs: An X-ray of the lower back typically ranges from about $200 to $285, an MRI from $875 to $1,225, and a CT scan from $1,080 to $1,520. Imaging accounts for a big chunk of the billions Americans spend for lower-back pain each year.
How X-rays work. An X-ray is a form of electromagnetic radiation that, when passed through an object, creates shadows of the structures within that object. X-rays pass through light molecular weight atoms like hydrogen, carbon, nitrogen and oxygen. These atoms make up skin, muscles and other soft tissues.
