Spine Imaging

Overview

Spine imaging uses radiography CT and MRI to evaluate degenerative disease trauma and infection. MRI is preferred for soft tissue and neural element assessment. Imaging guides surgical and conservative management.

Degenerative Disease

MRI assesses disc herniation spinal stenosis and nerve root compression. Imaging correlates with clinical findings to guide treatment. Advanced sequences evaluate marrow and inflammatory changes.

Trauma and Infection

CT detects fractures and bony injury in acute trauma. MRI identifies spinal cord injury infection and epidural abscess. Timely imaging supports urgent intervention when needed.

Postoperative Imaging

Imaging monitors hardware position fusion status and complications. CT and MRI provide complementary information in the postoperative spine. Clear communication with surgeons improves interpretation.

Spine Scoliosis Standing AP

Overview

Standing AP full spine radiographs evaluate coronal curvature and spinal alignment under physiologic load. The patient stands with arms positioned to avoid obscuring the spine. This view is essential for scoliosis screening and monitoring progression.

Technique

Obtain a full length AP radiograph from the cervical to the sacral region with the patient standing erect. Use consistent positioning and include a calibration marker for measurement. Ensure equal weight distribution and standardized arm positioning.

Clinical Indications

Full spine standing AP is indicated for scoliosis screening adolescent idiopathic scoliosis and preoperative planning. It quantifies Cobb angles and assesses coronal balance. Serial imaging monitors curve progression and treatment response.

Image Assessment

Measure Cobb angles identify curve apex and evaluate coronal balance and pelvic obliquity. Assess for vertebral anomalies and rotational deformity. Report findings to guide orthopedic management and bracing or surgical decisions.

Image Assessment

Assess vertebral body height alignment and look for lytic or sclerotic lesions. Evaluate for prevertebral soft tissue swelling and foreign bodies. Correlate with lateral and odontoid views for comprehensive interpretation.

Cervical Spine Lateral

Overview

The lateral cervical spine radiograph is the primary screening view for cervical trauma and alignment. The patient is positioned true lateral with the mandible and occiput clear of the cervical spine. This view assesses vertebral alignment prevertebral soft tissues and facet joints.

Technique

Center the detector to include the skull base to the upper thoracic spine and ensure true lateral alignment. Use a horizontal beam for trauma patients who cannot stand. Immobilize the head and instruct breath hold to minimize motion.

Clinical Indications

Lateral cervical spine is indicated for trauma neck pain and suspected instability. It helps detect subluxation fractures and prevertebral hematoma. CT is preferred for high risk trauma or when radiographs are inconclusive.

Image Assessment

Evaluate anterior and posterior vertebral body lines and spinolaminar alignment. Assess disc spaces and prevertebral soft tissue thickness. Report any malalignment or fracture and recommend advanced imaging when needed.

Cervical Odontoid AP Open Mouth

Overview

The open mouth odontoid radiograph images the odontoid process and lateral masses of C1 and C2. The patient opens the mouth and the beam is centered through the oral cavity. This view is essential for detecting odontoid fractures and atlantoaxial alignment.

Technique

Instruct the patient to open the mouth wide and align the lower edge of the upper incisors with the base of the skull. Center the detector to the open mouth and use appropriate exposure. Immobilize the head to reduce motion and ensure patient comfort.

Clinical Indications

Odontoid view is indicated for trauma with suspected C1 C2 injury and neck pain. It helps detect fractures of the dens and lateral mass displacement. CT is often used for detailed evaluation when radiographs are limited.

Image Assessment

Assess the odontoid process for cortical disruption and evaluate lateral mass symmetry. Look for atlantoaxial subluxation and prevertebral soft tissue swelling. Report findings and recommend CT for surgical planning when indicated.

Thoracic Spine AP

Overview

The AP thoracic spine radiograph evaluates vertebral bodies and alignment across the thoracic region. The patient is positioned upright or supine with the detector centered to the thoracic spine. This view complements lateral imaging for comprehensive assessment.

Technique

Center the detector to include T1 to T12 and use appropriate exposure to penetrate the thorax. Ensure the patient is not rotated and immobilize to reduce motion. Use scoliosis or oblique views when indicated for specific pathology.

Clinical Indications

AP thoracic spine is indicated for trauma back pain and suspected vertebral lesions. It helps detect compression fractures and metastatic disease. CT and MRI provide detailed evaluation for complex pathology.

Image Assessment

Assess vertebral body height alignment and look for lytic or sclerotic lesions. Evaluate rib articulation and costovertebral joints for associated injury. Correlate with lateral views for comprehensive interpretation.

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 AP

Overview

The AP lumbar spine radiograph evaluates vertebral bodies sacral alignment and pelvic landmarks. The patient is positioned supine or upright with the detector centered to the lumbar region. This view complements lateral imaging for comprehensive lumbar assessment.

Technique

Center the detector to include L1 to S1 and ensure the patient is not rotated. Use appropriate exposure and immobilize the patient to reduce motion. Include the sacroiliac joints when indicated for pelvic pathology.

Clinical Indications

AP lumbar spine is indicated for low back pain trauma and suspected vertebral lesions. It helps detect spondylolisthesis and degenerative change. MRI provides detailed evaluation for disc and neural element pathology.
