Spinal X-rays are also done to check the curve of your spine (scoliosis) or for spinal defects.
X-rays are a form of radiation, like light or radio waves, that are focused into a beam, much like a flashlight beam. X-rays can pass through most objects, including the human body.
Dense tissues in the body, such as bones, block (absorb) many of the X-rays and look white on an X-ray picture. Less dense tissues, such as muscles and organs, block fewer of the X-rays (more of the X-rays pass through) and look like shades of gray on an X-ray. X-rays that pass only through air look black on the picture.
Before the X-ray test, tell your doctor if you:
- Are or might be pregnant. The risk of radiation exposure to your unborn baby (fetus) must be considered. The risk of damage from the X-rays is usually very low compared with the potential benefits of the test. If a spinal X-ray is absolutely necessary, a lead apron will be placed over your belly to shield your baby from the X-rays.
- Have had an X-ray test using barium contrast material (such as a barium enema) in the past 4 days. Barium shows up on X-ray films and makes it hard to get a clear picture of the lower back (lumbar spine).
You don’t need to do anything else before you have this test.
Excellent doctor and staff. Shawn and Mike are the best! Great service!!
