Flashcards in Ribs Deck (7)
AP Projection: Posterior ribs: Pt position:
Erect position is preferred for above diaphragm if pt's condition allows and supine for below diaphragm.
AP Projection: Posterior ribs: Part position:
Align midsagittal plane to CR and to midline of grid or table/upright Bucky.
Rotate shoulders anteriorly to remove scapulae from lung fields.
Raise chin to prevent it from superimposing upper ribs; look straight ahead.
Allow no rotate of thorax or pelvis.
AP Projection: Posterior ribs: CR
Above diaphragm: CR perpendicular to IR, centered to 3 or 4 inches below jugular notch (level of T7)
IR centered to level of CR (top of iR should be about 1.5" above shoulders)
Below diaphragm: CR perpendicular, centered to level of xiphoid process.
IR centered to CR (lower margin of IR at iliac crest)
AP Projection: Posterior ribs: Respiration:
Suspend respiration on inspiration for ribs above the diaphragm and on expiration for ribs below the diaphragm.
AP Projection: Posterior ribs: Evaluation Criteria: Anatomy demonstrated:
Above diaphragm, ribs 1 through 10 should be visualized. Below diaphragm: ribs 9 through 12 should be visualized.
AP Projection: Posterior ribs: Evaluation Criteria: Position:
Rotation of the thorax should not be evident. Collimation to area of interest.
