Thoracic Spine Lateral

Overview

The lateral thoracic spine radiograph profiles vertebral body heights and intervertebral disc spaces to detect compression fractures and kyphosis. The patient is positioned true lateral with arms elevated to clear the thoracic region. This view is sensitive for anterior wedge compression and alignment abnormalities.

Technique

Center the detector to include the thoracic spine and ensure true lateral alignment with minimal rotation. Use appropriate exposure and immobilize the patient to reduce motion. Consider full spine imaging for scoliosis assessment.

Clinical Indications

Lateral thoracic spine is indicated for trauma back pain and suspected compression fractures. It helps evaluate sagittal balance and vertebral body collapse. MRI is used for spinal cord and soft tissue assessment when indicated.

Image Assessment

Measure vertebral body heights and assess for anterior wedge deformity and kyphotic angulation. Evaluate disc spaces and posterior element alignment. Report findings and recommend advanced imaging for neurologic compromise.

Lumbar Spine Lateral

Overview

The lateral lumbar spine radiograph profiles vertebral bodies intervertebral disc spaces and posterior elements to detect spondylolisthesis and compression fractures. The patient is positioned true lateral with knees flexed for comfort. This view is essential for evaluating sagittal balance and neural foramina indirectly.

Technique

Center the detector to include L1 to S1 and ensure true lateral alignment with minimal rotation. Use appropriate exposure and immobilize the patient to reduce motion. Flex knees to reduce lumbar lordosis when needed for better visualization.

Clinical Indications

Lateral lumbar spine is indicated for low back pain trauma and suspected compression fractures. It helps assess disc height spondylolisthesis and vertebral collapse. MRI is preferred for direct neural element and disc pathology evaluation.

Image Assessment

Measure disc heights and vertebral body alignment and assess for anterior or posterior displacement. Evaluate for compression fractures and osteophyte formation. Report findings relevant to surgical planning and conservative management.
