A number of test may be used to aid in the diagnosis of spondylolisthesis and to locate the affected bone, including:
X-ray -- High-energy radiation is used to take pictures of the spine.
Magnetic Resonance Imaging (MRI) Scan-- An MRI provides detailed pictures of the spine that are produced with a powerful magnet linked to a computer.
Computed Tomography (CT) Scan -- A CT scan uses a thin X-ray beam that rotates around the spine area. A computer processes data to construct a three-dimensional, cross-sectional image.
