- Locate growths influencing the bones or nerves of the spinal column. The lumps that a lot of typically infected the spinal column consist of those from bust, prostate, or lung cancer cells.
- Discover compression cracks of the back.
- Inspect locations of joint swelling (joint inflammation) or bone loss discovered throughout an X-ray examination or a bone check.
- Discover locations of the spinal column that do not have excellent blood supply.
- Discover an infection.
- Locate nerve damages dued to injury or illness, such as several sclerosis.
- Examine issues of the back that have actually existed because birth (hereditary).
