Critique of the Sternum and Ribs
Chapter 9
Sternum (RAO)
Contrast & density to see jugular notch, manubrium, sternal body, & xiphoid process (60-70 kVp)This view rotates the sternum from behind the T-spine30 inch SID/ breathing technique/ 3 to 4 second exposure timeRotation 15-20 degrees, Sternum should be within heart shadowMidsternum in center of field
Sternum (lateral)
70 to 75 kVp
manubrium, sternal body & xiphoid process seen in profile with no superimposition of the anterior ribs over the sternum
Midsternum in center of field
Position getting patient in full inspiration
Ribs ( AP & PA)
65 to 70 kVp (upper)75 to 80 kVp (lower)When fractures occur, other pathology is closely looked for. Pneumothorax, emphysema, rupture of trachea, bronchus, or aortaFor lower pathology, kidney, liver, spleen or diaphragm damageFor anterior rib pain, do PA projection to place them closer to film/ and vice versa
AP or PA of Ribs above diaphragm
For AP & PA remove scapula from lung field
See 9 posterior ribs above diaphragm
7th posterior rib in center of field (halfway between jugular notch & xiphoid process)
Full inspiration
AP & PA of Ribs below diaphragm
9th – 12th posterior ribs seen below diaphragm
Use higher kVp to penetrate abdominal tissue
9th or 10th posterior rib in center of field halfway between sternum and xiphoid process
For hypersthenic patient with short, wide thorax, place lower border of cassette 2 inches above the crest, then center central ray to film
Ribs (anterior & posterior obliques)
65 to 70 kVp upper/ 75 to 80 kVp lower
Axillary rib detail is best in posterior oblique / axillary ribs closest to film and better view of sternum
Thorax rotated 45 degrees/ the inferior sternum is positioned halfway between the vertebral column and anterior ribs
Posterior & Anterior oblique Ribs above & below diaphragm
9 axillary ribs seen/ full inspiration
?7th axillary rib in center of field
Below: 9th – 12th axillary ribs seen expiration
9th or 10th axillary rib in center of field
