Chest Flashcards
Projection?
Stuctures showns?
-Soft Tissue Neck
-Shows air-filled upper airway or trachea and superior mediastinum
-Under normal condition the air way is superimmposed on the shadow of the cervical vertebrae
Evaluation
-Air filled upper airway from the pharynx to the proximal trachea (upperairway)
-Air filled airway from the midcervical to the midthoracic region (for trachea and superior mediastinum
Projection?
Structures shown?
-Lateral soft tissue neck (R or L position)
-Air filled upper airway or the trachea and superior mediastinum
-Also used to locate foreign bodies
Evaluation? (3)
-No rotation or tilt of the cervical spine
-Superimposed zygpophyseal joint and open intervertebral joints
-Superimposed or nearly superimosed mandibular rami
Projection?
Structures?
-PA Chest
-Thoracic viscera shows the air filled trachea, the lungs,the diapragmatic domes, the heart and aortic arch and if enlarged laterally, the thyroid or thymus gland
-The bronchial tree is shown from an oblique
Evaluation? (5)
-NO rotation
-Sternal end of clavicles equidistant from vertebral column
-Trachea visible
-Equal distance from the ebral column to lateral border of the ribs on each side
-Proper inspiration shows by 10 posterior ribs visible above the diphragm at least one less rib visible on expiration
Projection?
Structures?
-Lateral Projection (R or L position)
-Left position show heart, aorta and left sided pulmonary lesions
Evaluation
-Costophernic angles
-Portions of the pulmonary apes not obscured by the arms and shoulders
-No rotation
-Hila in the approximate center of the xray
Projection?
Position of part?
-AP projection (supine or upright)
-Adjust IR so the upper border 1.5 to 2” above the relaxed shoulders
Strutures shown? (3)
Similar to PA projection but being frther from the IR
-Heart and great vessels are magnified and engorged
-The lung field appear short bc abdominal compression moves the diaphragm to a higher level
Projection?
Sructures shown?
Lindblom method (Lordotic position)
-Image of the lungs show the apices and conditions sucs like interlobar effusions
-Clavicles located superior to the apices
Projection?
Central ray?
Structures?
AP Axial projection
-DIrected at an angle of 15 or 20 degrees cephalad to the center of the IR and entering the manubrium
-Shows apices lying below the clavicles
Projection?
Central ray?
strcutures shown?
-PA Axial projection
-Directed 10 to 15 degrees cephalad through T3 to the center of the IR
-Apices are projected above the shadows of the clavicles in the PA axial and PA projection
Projection?
Structures?
-Lateral R OR L position
Ventral or dorsal decubitus postion
-Shows change in the position of fluid and reveals pulmonary areas that are obscured by the fluid in standard projections
