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.
