The X-Ray – Dorsal / Thoracic Spine AP or LAT is a diagnostic imaging procedure used to examine the thoracic (dorsal) region of the spine, which forms the mid-back. This test may include either an anteroposterior (AP) view, showing the spine from front to back, or a lateral (LAT) view, providing a side profile.

The AP view is useful for assessing overall alignment, vertebral structure, and symmetry, while the lateral view helps evaluate spinal curvature, vertebral height, and intervertebral disc spaces. Depending on the clinical requirement, one or both views may be performed.

This test is commonly used to detect fractures, compression injuries, spinal deformities such as kyphosis, and degenerative changes. It is also helpful in diagnosing causes of mid-back pain and monitoring known spinal conditions.

The procedure is quick, non-invasive, and plays an important role in accurate diagnosis and treatment planning.

This test is recommended for individuals experiencing symptoms related to the mid-back.

It is advised in the following cases:

• Persistent mid-back pain
• Injury or trauma to the spine
• Suspected vertebral fractures
• Postural abnormalities or spinal deformities
• Limited mobility or stiffness
• Suspected degenerative spine conditions
• Follow-up evaluation after treatment
