thorax Flashcards
allows the sternum to be visualized in a lateral orientation that compliments the RAO position
STERNUM
LATERAL PROJECTION
PP AND SID OF STERNUM
LATERAL PROJECTION
- Suspend on inspiration to provide sharper contrast between the superior surface of the sternum and adjacent structures
- SID 72 INCHES
- top of IR 1.5 inch above jugular notch
performed to prevent superimposition by the thoracic vertebra to the sternum in true PA projection.
STERNUM:
PA OBLIQUE PROJECTION
RAO POSITION
CR OF PA Oblique RAO position (STERNUM)
Perpendicular to 1 inch lateral to MSP
PP OF STERNUM:
PA OBLIQUE PROJECTION
RAO POSITION
- body 15-20 degrees towards the right side (left side elevated) to prevent superimposition of the sternum and
vertebra - instruct the patient to take slow, shallow breaths during exposures.

Best demonstrate the anterior ribs above the diaphragm (ribs 1-9th or 10th visualized above the diaphragm)
