What are the lungs?
How the patient is positioned for a Lateral Soft Tissue Neck?
What is seated or standing in a lateral position?
Accumulation of air in the plural cavity resulting in collapse of the lung
What is pneumothorax?
Evaluation criteria for AP Soft Tissue Neck
Pharynx to proximal trachea (for upper airway)
Midcervical to midthoracic region (for trachea and superior mediastinum)
No rotation – equidistant spinous processes to pedicles
Bony trabecular detail and soft tissue
Why do we do decubitus positions?
What is air fluid levels?
Located in front of the vertebrae and behind the nose, mouth, and larynx
What is the pharynx?
The CR for an AP Soft Tissue Neck
What is Perpendicular through MSP at the level of the laryngeal prominence or manubrium?
collapse of all or part of the lung
What is Atelectasis?
Evaluation Criteria for AP Axial Chest
Clavicles lying horizontally with their sternal ends overlapping only the first or second ribs
Ribs distorted with their anterior and posterior portions superimposed
Entire apices and appropriate portion of lungs
Clavicles located superior to the apices
Sternal ends of the clavicles equidistant from the vertebral column
What is 5 minutes?
The superior portion of the lungs
What are the apices?
The IR for a PA Chest
What is 1.5 to 2 inches above shoulders?
Inflammation of the epiglottis
What is epiglottitis?
Evaluation criteria for lateral decubitus position
Affected side in its entirety
No rotation of the patient
Patient’s arms not visible in the field of interest
Faintly visible spine and pulmonary vascular markings from the hilar regions to the periphery of the lungs
The kVp used for PA Chest, Lateral Chest, and AP Axial Chest
What is 120 kVp?
The space between your lungs.
What is the pleural cavity?
The coronal plane of thorax is ______ from the vertical in an AP Axial Chest

Acute infection in the lung parenchyma
What is pneumonia?
Evaluation criteria for AP Chest
Sternal ends of the clavicles equidistant from the vertebral column
Trachea visible in the midline
Equal distance from the vertebral column to the lateral border of the ribs on each side
Clavicles lying more horizontally than in the PA projection
Approximately 1 inch of the pulmonary apices seen superior to the clavicles
Pleural vascular markings visible from the hilar regions to the periphery of the lungs
The respiration phase for all Chest imaging
What is full inspiration? (After the second full inspiration)
The sides of the lungs

The CR for a ventral decubitus chest
What is horizontal and perpendicular to IR, entering at level of T7
Condition of unknown origin often associated with pulmonary fibrosis
What is Sarcoidosis?
Evaluation criteria for PA Chest
Sternal ends of the clavicles equidistant from the vertebral column
Trachea visible in the midline
Equal distance from the vertebral column to the lateral border of the ribs on each side
Scapulae projected outside the lung fields
10 posterior ribs visible above the diaphragm
Sharp outlines of heart and diaphragm
Faint shadows of the ribs and superior thoracic vertebrae visible through the heart shadow
Lung markings visible from the hilum to the periphery of the lung
The respiration phase for upper airway imaging
During slow inspiration
