Chest AP Semi Upright
4
Feb

Overview

The AP semi upright chest radiograph is used when full upright positioning is not possible. The patient sits or reclines with the detector behind the back. This view provides better visualization than supine imaging while accommodating limited mobility.

Technique

Ensure the detector is positioned to capture the entire thorax and instruct the patient to inhale. Use support devices to stabilize the patient and minimize motion. Record the degree of upright positioning on the study.

Clinical Indications

Semi upright AP chest is useful for patients with limited tolerance for standing. It aids in assessing pulmonary edema pleural effusion and lines. It is a compromise between supine and full upright imaging.

Image Assessment

Account for projectional differences when evaluating heart size and lung volumes. Look for layering pleural fluid and central vascular congestion. Recommend upright imaging if clinical condition allows for improved assessment.

Rib Series AP Upright

Feb

Overview

AP rib radiographs evaluate suspected rib fractures and chest wall pathology. Images are obtained with the patient upright and centered to the area of interest. Multiple projections may be required to visualize the entire rib arc.

Technique

Obtain separate views for upper and lower ribs as needed with appropriate collimation. Use oblique projections to profile ribs and reduce overlap with the spine. Provide pain control and positioning aids for patient comfort.

Clinical Indications

Rib series are indicated for trauma chest pain and suspected fractures. They help detect displaced fractures and associated complications such as pneumothorax. CT is more sensitive for occult fractures when radiographs are inconclusive.

Image Assessment

Evaluate cortical continuity and callus formation on follow up studies. Assess for adjacent lung injury and pleural air or fluid. Document fracture location and displacement for clinical management.

Clavicle AP

Overview

AP clavicle radiographs evaluate suspected clavicular fractures and alignment. The patient is positioned upright or supine with the detector centered to the clavicle. Additional angled views may improve visualization of fracture displacement.

Technique

Center the detector to include the entire clavicle from sternoclavicular to acromioclavicular joints. Use a slight cephalad tube angle if needed to project the clavicle above the ribs. Immobilize the arm to reduce motion.

Clinical Indications

AP clavicle is indicated for trauma shoulder pain and suspected fracture. It helps determine fracture location and displacement for management decisions. Follow up radiographs monitor healing and callus formation.

Image Assessment

Evaluate cortical continuity and alignment of the clavicle segments. Assess for shortening and involvement of adjacent joints. Document fracture type and recommend orthopedic consultation when indicated.
