Magnetic resonance imaging (MRI) of the spine is a noninvasive procedure that uses powerful magnets and radio waves to create pictures of the spine area, including the vertebrae (spine bones), the spinal cord, and the spaces between the vertebrae through which the nerves travel.See also: MRI

A lumbosacral spine x-ray is a picture of the small bones (vertebrae) in the lower part of the spine (the lumbar region) and the sacrum, the area that connects the spine to the pelvis.

A lumbosacral spine MRI uses powerful magnets and radio waves to create pictures of the structures that make up the spine, the spinal cord, and the spaces between the vertebrae, through which the nerves travel.Conventional radiography and computed tomographic (CT) imaging use potentially harmful radiation (x-rays) that passes through a patient to generate images. Magnetic resonance imaging (MRI) is based on the magnetic properties of atoms, and there is no exposure to the same type of radiation used in x-rays and CT scans.A powerful magnet generates a magnetic field roughly 10,000 times stronger than the Earth's. A very small percentage of hydrogen atoms within the body will align with this field. Radio wave pulses are broadcast towards the aligned hydrogen atoms in tissues of interest, returning a signal of their own. The slight differences of those signals from different tissues enables MRI to tell the difference between various organs, and potentially, provide contrast between benign and malignant tissue.Any imaging angle, or "slice", can be projected, and then stored in a computer or printed on film. MRI can easily be performed through clothing and bones. However, certain types of metal in or around the area of interest can cause significant errors in the reconstructed images.

A thoracic spine x-ray is an x-ray of the twelve chest (thoracic) vertebrae. The vertebrae are separated by flat pads of cartilage that cushion them.

Spinal fusion is surgery to correct problems in the spine bones (vertebrae). The surgery stabilizes the back by fusing certain bones in the spine together. Fusing means two bones are permanently placed together (“fused”) so that movement between them can no longer occur.

Scoliosis is a curving of the spine. The spine curves away from the middle or sideways.

Spinal cord trauma is damage to the spinal cord. It may result from direct injury to the cord itself or indirectly from damage to surrounding bones, soft tissues, and blood vessels.
