What is this test?
This test involves taking X-ray images of the lower back (lumbar spine) from two angles: front (anteroposterior, AP) and side (lateral). These images help visualize the vertebrae, discs, and surrounding structures in the lumbar region.
What is it used for?

• Diagnosing fractures or injuries to the lumbar vertebrae
• Detecting signs of arthritis or degenerative disc disease
• Assessing spinal alignment and any deformities such as scoliosis or lordosis
• Evaluating causes of chronic lower back pain or sciatica
• Monitoring known spinal conditions and treatment progress

Who should get this test?

• Patients suffering from persistent or acute lower back pain
• Individuals with symptoms like sciatica, numbness, or weakness in the legs
• Those with a history of trauma or injury to the lower back
• Patients with suspected degenerative spinal disorders or deformities

Preparation Required:

• Remove any clothing or accessories covering the lower back to avoid image interference.
• Wear comfortable clothes; you may be asked to change into a gown.

How is the procedure performed?
You will either stand or lie on the X-ray table, depending on the facility’s protocol. The technician takes two images — one from the front and one from the side — which usually only takes a few moments.
Risks & Safety:
This procedure uses low-dose ionizing radiation, which is generally safe when medically necessary. Protective shielding may be used to minimize exposure.
Results:
A radiologist carefully examines the images to identify fractures, arthritis, disc space narrowing, or alignment issues, then provides a detailed report to your doctor.
