Feb

Overview

The AP skull radiograph evaluates cranial vault symmetry and gross osseous lesions. The patient is positioned upright or supine with the detector centered to the skull. This view is used for initial assessment in trauma and suspected skull pathology.

Technique

Center the detector to include the entire skull and ensure the orbitomeatal line is perpendicular to the detector for standard AP projection. Use appropriate exposure and immobilize the head to reduce motion. Collimate to the skull to minimize dose.

Clinical Indications

AP skull is indicated for trauma suspected fracture and evaluation of lytic or sclerotic lesions. CT is preferred for detailed assessment of skull fractures and intracranial injury. Radiographs may be used when CT is unavailable.

Image Assessment

Pediatric Chest AP
4
Feb

Overview

Pediatric AP chest radiographs are tailored for children and infants to evaluate respiratory disease and congenital anomalies. The projection is often AP due to patient cooperation and equipment constraints. Exposure factors are adjusted to minimize radiation dose while maintaining diagnostic quality.

Technique

Use size specific exposure settings and immobilization aids to reduce motion. Position the child supine or upright as tolerated and center the detector to the chest. Provide comfort measures and parental presence to improve cooperation.

Clinical Indications

Pediatric chest radiographs are indicated for suspected pneumonia bronchiolitis and congenital heart disease evaluation. They assess lung volumes cardiac size and airway position. Ultrasound and CT are used selectively when additional detail is required.

Image Assessment

Evaluate lung aeration perihilar markings and cardiac silhouette appropriate for age. Look for air bronchograms lobar consolidation and foreign bodies. Report findings with pediatric specific considerations and recommend follow up imaging when indicated.

Weightbearing Foot AP Lateral
4
Feb

Overview

Weightbearing foot radiographs assess alignment and joint space under physiologic load. AP and lateral weightbearing views reveal flatfoot cavus deformity and joint collapse not seen on non weightbearing studies. These views guide orthotic and surgical planning.

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

Evaluate arch height talonavicular coverage and metatarsal alignment under load. Assess joint space narrowing and subluxation. Report findings relevant to orthotic prescription and surgical planning.

Cervical Spine AP
4
Feb

Overview

The AP cervical spine radiograph evaluates vertebral body alignment and gross pathology. The patient is positioned upright or supine with the detector centered to the cervical region. This view complements lateral and odontoid projections for comprehensive cervical assessment.

Technique

Center the detector to include C3 to T1 and use appropriate exposure to penetrate the shoulders and neck. Ensure the patient is not rotated and immobilize the head to reduce motion. Use swimmer technique or oblique views if lower cervical vertebrae are obscured.

Clinical Indications

AP cervical spine is indicated for trauma neck pain and suspected vertebral body pathology. It helps detect gross malalignment and destructive lesions. CT and MRI provide detailed evaluation for fractures and soft tissue injury.

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.

Thoracic Spine AP
4
Feb

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.

Lumbar Spine AP
4
Feb

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.

Image Assessment

Assess vertebral body heights alignment and look for spondylolisthesis or lytic lesions. Evaluate sacral slope and pelvic parameters when relevant. Correlate with lateral views for comprehensive interpretation.

Sacrum Coccyx AP

Feb

Overview

The AP sacrum and coccyx radiograph evaluates the lower spine and pelvic ring for fractures and degenerative change. The patient is positioned supine with the detector centered to the sacrum. This view is used for trauma and chronic tailbone pain assessment.

Technique

Center the detector to include the sacrum and coccyx and use appropriate tube angulation if needed to project the sacrum free of pelvic superimposition. Ensure patient comfort and immobilize to reduce motion. Collimate tightly to reduce dose.

Clinical Indications

AP sacrum and coccyx are indicated for trauma tailbone pain and suspected fracture or infection. They help detect sacral insufficiency fractures and coccygeal dislocation. CT or MRI may be required for detailed evaluation.

Ankle AP Mortise

Feb

Overview

The AP mortise ankle radiograph visualizes the ankle joint with the mortise open by internally rotating the foot approximately 15 degrees. This projection displays the tibial plafond talar dome and fibular relationship. It is standard for ankle trauma and arthritis evaluation.

Technique

Internally rotate the foot to align the malleoli parallel to the detector and center to the ankle joint. Ensure the entire mortise is included and use appropriate exposure. Immobilize the limb to reduce motion artifact.
