Feb

Overview

The lateral skull radiograph profiles the cranial vault and facial bones to assess fractures and soft tissue calcifications. The patient is positioned true lateral with the orbitomeatal line parallel to the detector. This view complements AP imaging for comprehensive skull assessment.

Technique

Position the head in true lateral and center the detector to include the entire skull from the frontal sinus to the occiput. Use appropriate exposure and immobilize the head to minimize motion. Collimate to the skull to reduce dose.

Clinical Indications

Lateral skull is indicated for trauma suspected fracture and evaluation of sinus disease or calcifications. CT is preferred for detailed assessment of fractures and intracranial pathology. Radiographs may be used for screening or when CT is not available.

Image Assessment

Evaluate cranial vault contour suture lines and paranasal sinus aeration. Inspect for depressed fractures and soft tissue emphysema. Recommend CT for definitive assessment of suspected intracranial injury.

Nasal Bones AP Lateral

Feb

Overview

AP and lateral nasal bone radiographs assess nasal bone alignment and detect fractures. The AP view images the nasal bones en face while the lateral view profiles displacement. These views are used for initial trauma assessment when CT is not immediately available.

Technique

Obtain AP and lateral projections with the detector centered to the nasal bones and use appropriate exposure. Ensure minimal rotation and immobilize the head to reduce motion. Remove external nasal splints or dressings when safe to do so.

Clinical Indications

Nasal bone radiographs are indicated for trauma with suspected nasal fracture and deformity. They help detect displaced fractures and septal deviation. CT provides detailed assessment for complex facial trauma and surgical planning.

Image Assessment

Assess nasal bone continuity displacement and associated soft tissue swelling. Evaluate for septal hematoma and recommend ENT consultation when indicated. Document findings relevant to cosmetic and functional outcomes.

Weightbearing Foot AP Lateral

Technique

Obtain AP and lateral radiographs with the patient standing and bearing equal weight on both feet. Center the detector to the mid foot and use appropriate exposure for increased soft tissue thickness. Ensure consistent foot positioning for serial comparison.

Clinical Indications

Weightbearing foot views are indicated for deformity assessment hallux valgus and arthritis evaluation. They reveal functional collapse and alignment issues relevant to treatment. Non weightbearing views may underestimate deformity severity.

Image Assessment

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.

Thoracic Spine Lateral
4
Feb

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
4
Feb

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.

Sacrum Coccyx Lateral
4
Feb

Overview

The lateral sacrum and coccyx radiograph profiles the lower spine to assess alignment and fractures. The patient lies in true lateral with the detector centered to the sacrum. This view is useful for evaluating coccygeal angulation and sacral fractures.

Technique

Position the patient in true lateral and center the detector to include the sacrum and coccyx. Use appropriate exposure and immobilize the patient to minimize motion. Include adjacent pelvic structures when indicated.

Clinical Indications

Lateral sacrum and coccyx are indicated for trauma tailbone pain and suspected fracture or dislocation. They complement AP views for comprehensive assessment. CT or MRI may be required for detailed evaluation of complex injuries.

Image Assessment

Evaluate coccygeal angulation sacral body integrity and posterior element alignment. Inspect for cortical disruption and callus formation on follow up. Report findings relevant to pain management and surgical planning.

Knee Lateral

Feb

Overview

The lateral knee radiograph profiles the femorotibial joint patella and soft tissues to assess effusion and fractures. The knee is flexed approximately 20 to 30 degrees for optimal visualization. This view is essential for trauma and preoperative evaluation.

Technique

Position the patient in true lateral with femoral condyles superimposed and the knee flexed. Center the detector to the joint and include the distal femur and proximal tibia. Use appropriate exposure and immobilize the limb.
