Although you don't need to make any special preparations before taking a bone scan, you should dress in comfortable, easily removed clothes and refrain from wearing any jewelry. Metal jewelry and watches, in particular, should be left at home or removed just prior to the bone scan because they can affect the results.  Like other diagnostic imaging tests, such as x-rays, any metal on your body will make the bone scan images look white or lighter than surrounding areas. Tell the radiologist and/or technician if you have any metal fillings in your mouth or metal implants in your body, so they can make note of it and not confuse them with diseases processes. Wearing clothes that are easily removed is a good idea because you may be asked to wear a hospital gown. Inform your doctor if your pregnant or potentially pregnant because the radiation exposure from the radiotracer can be harmful to the baby. As such, bone scans aren't often performed on pregnant women or nursing mothers — the breast milk can become slightly radioactive and harm the baby also.  There are other imaging tests for bone that are safer for pregnant women, such as MRI studies and diagnostic ultrasound. Short-term osteoporosis is not uncommon with pregnant women who are malnourished because minerals are leached from their bones to provide for the growing baby. Although you can eat and drink normally just prior to your bone scan, tell your doctor about the medications you're taking, as these may affect your test. For example, medicines that contain barium or bismuth affect bone scan test results, so you should avoid taking them for at least four days prior to your appointment.  Bismuth is found in a variety of medicinal products, such as Pepto-Bismol, Kaopectate, Devrom and De-Nol. Bismuth and barium can cause areas of your body to look too light on bone scans
