Spinal X-Ray
X-rays can used to detect causes of back pain throughout the spinal column; two kinds are engaged specifically for testing for the causes of lower back back. A lumbosacral spine X-ray focuses on the five bones of the lower back known as the lumbar vertebrae as well as the five fused bones located at the bottom of the spin, known as the sacrum. The sacrum/coccyx X-ray will also give a picture of the sacrum as well as of the four small bones that make up the coccyx, or tailbone. X-rays test for a number of potential causes of lower back pain, including bone degeneration, crushed discs, tumors, fractures and bone spurs.
Computerized Tomography (CT Scan)
A CT scan is essentially an X-ray, but one that offers far more detail than traditional X-rays. The primary advantage is that CT scans return cross section images that provide more information about the bones in the spine. This information allows the technician to narrow the test down to specific conditions that cause back pain, including herniated discs and pinched nerves.
Magnetic Resonance Imaging (MRI)
MRI scanning is typically more accurate at diagnosing certain back problems than a CT scan. The MRI provides much more comprehensive detailing of the intervertebreal disc and nerve roots. For this reason, the MRI scan is an excellent method for testing for lower back pain caused by pinched nerves. In addition, MRI is also effective for ruling out certain causes of pain, such as tumors and infection.
Bone Scan
A bone scan requires the injection of a radioactive substance into the bloodstream that identifies abnormalities such a new bone growth or breakdown of the bone. Bone scan are useful for detecting bone cancer, trauma and infection that can lead to potentially serious lower back pain and associated conditions and diseases.
