Positioning
This chest projection requires the patient to take a second full inspiration to ensure adequate lung expansion.
What is PA chest?
This structure passes through the intervertebral foramen.
What is a spinal nerve?
Doubling mAs will have this effect on image receptor exposure.
What is doubling the exposure?
This type of fracture involves the bone being broken into multiple fragments.
What is a comminuted fracture?
In trauma, this projection is preferred for the lateral cervical spine to avoid patient movement.
What is cross-table lateral?
Failure to flex the knees on an AP lumbar spine results in increased visualization of this.
What is the lumbar lordotic curvature?
The lesser trochanter is best visualized in this hip position.
What is external rotation?
Increasing kVp decreases this type of image quality.
What is contrast?
A radiopaque area in the lung fields may indicate this condition involving infection and fluid.
What is pneumonia?
This imaging approach is used when a patient cannot stand or be repositioned due to injury severity.
What is a portable (bedside) X-ray / horizontal beam imaging?
In a properly positioned lateral knee, these structures should be superimposed.
What are the femoral condyles?
This carpal bone articulates directly with the radius.
What is the scaphoid?
Increasing SID from 40” to 80” requires this exposure adjustment to maintain receptor exposure.
What is increase mAs (4x)?
This fracture involves the neck of the 5th metacarpal and is commonly caused by punching an object with a closed fist.
What is a boxer’s fracture?
When performing trauma imaging of the cervical spine, this vertebral level must be visualized to safely clear the spine.
What is the C7–T1 junction?
For an AP axial clavicle, increasing CR angulation helps project the clavicle away from these structures.
What are the ribs and scapula?
This part of the sternum articulates with the clavicles.
What is the manubrium?
This interaction produces scatter radiation that degrades image quality but does not result in total absorption.
What is Compton scatter?
A fracture where one side of the bone bends and the other breaks, common in pediatrics.
What is a greenstick fracture?
If a trauma patient cannot be rotated for an oblique, this alternative imaging approach is used.
What is cross-table or modified projections?
A lateral chest radiograph shows the posterior ribs not superimposed, indicating rotation. To correct this, the technologist should adjust the patient so this plane is perpendicular to the IR.
What is the midcoronal plane (MCP)?
This anatomical structure divides the thoracic cavity into superior and inferior portions (radiographically important landmark).
What is the diaphragm?
If kVp is increased by 15%, this compensatory change maintains image receptor exposure.
What is halve the mAs?
A chest radiograph shows a sharp white line with no lung markings beyond it, indicating collapsed lung tissue.
What is a pneumothorax?
A trauma patient has a suspected long bone injury. To avoid missing additional injuries, what must the technologist include in the image?
What are the joints above and below the injury?
