Pulmonary Imaging

  1. 1. Chest X-Ray Collection By AMIR B.CHANNA FFARCS,DA (Eng) King Khalid Univ. Hospital Riyadh KSA
  2. 2. Most important things when reading a CXR… <ul><li>Have a System </li></ul><ul><li>Use it consistently </li></ul><ul><li>Know your anatomy </li></ul><ul><li>Diff. diagnosis & Pathophysiology </li></ul>
  3. 3. Have a System…
  4. 4. Step #1: Always, always, always… Confirm the patient’s name & check date on film
  5. 5. Step #2: Know a good CXR when you see one… assess the film’s quality HOW ?
  6. 6. Assessing Quality: R.I.P. <ul><li>R  Rotation </li></ul><ul><ul><li>clavicles- symmetric & flush with sternum </li></ul></ul><ul><li>I  Inspiration </li></ul><ul><ul><li>want to see at least 8-9 ribs for a good film </li></ul></ul><ul><li>P  Penetration </li></ul><ul><ul><li>should see vertebral bodies thru the heart </li></ul></ul>
  7. 7. Step #3: Read the film… DO NOT JUMP TO DIAGNOSIS
  8. 8. My System: the Short Version: ( Use this for routine films) <ul><li>A  Airways </li></ul><ul><li>B  Bones & soft tissues </li></ul><ul><li>C  Cardiac silhouette </li></ul><ul><li>D  Diaphragm </li></ul><ul><li>E  Everything else… the lungs </li></ul>
  9. 9. The Long Version: Use this system for more complicated films on the wards & at Morning Report <ul><li>R  Rotation (clavicles- symmetric & flush with sternum) </li></ul><ul><li>I  Inspiration (want to see at least 8-9 ribs for good film) </li></ul><ul><li>P  Penetration (should see vertebral bodies thru the heart) </li></ul><ul><li>A  Airways (trachea shifted or irregular, bronchiectasis, ETT) </li></ul><ul><li>B  Bones (frxs, osteoporosis, lytic lesions, skeletal deform’s) </li></ul><ul><li>C  Cardiac silhouette (CM, chamber enlargements, aorta, Ca ++ ) </li></ul><ul><li>D  Diaphragm (R higher L?, phrenic nerve palsy, pleural lesions) </li></ul><ul><li>E  Effusions (pleural/pericardial; effusion size, does it layer out) </li></ul><ul><li>F  Free air (under diaphragm, in sub-Q tissue, mediastinum) </li></ul><ul><li>G  GI pathology  gastric bubble (shifted by spleen) </li></ul><ul><li>H  Hilum (LAD, vascular congestion, calcifications/granulomas) </li></ul><ul><li>IJ  IJ catheters & other lines (confirm they are in the right place) </li></ul><ul><li>K  Kerley-B lines, Kypho-scoliosis and skeletal deformities </li></ul><ul><li>L  And finally… the LUNGS!!!!!!! </li></ul>
  10. 10. More Details on the Lungs: <ul><li>Features to look for when characterizing parenchymal lung disease: </li></ul><ul><li>Over/under inflation (<8 or >9 ribs visible) suggests a restrictive or obstructive process </li></ul><ul><li>Pneumothorax, atelectasis or volume loss </li></ul><ul><li>Air bronchograms or bronchiectasis </li></ul><ul><li>Infiltrates (describe as lobar, multi-lobar, diffuse) </li></ul><ul><li>Mass/nodule (+/-3cm), shape, cavity?, Ca ++? </li></ul><ul><li>Interstitial pattern (alveolar, reticular, miliary) </li></ul><ul><li>Distribution of infiltrates: apical, basilar, pleural </li></ul><ul><li>Vascular flow: oligemia? cephalization? </li></ul>
  11. 11. Know your anatomy…
  12. 16. Investigations <ul><li>Chest Radiograph </li></ul><ul><li>PA </li></ul><ul><li>AP </li></ul><ul><ul><li>Ill patient </li></ul></ul><ul><li>Lateral </li></ul><ul><ul><li>Mass localisation, cardiac chambers, hila </li></ul></ul><ul><li>Expiratory </li></ul>
