  1. CT Chest and Abdomen for Beginners Arcot Chandrasekhar, M.D. Hema Chandrasekhar, M.D.

  2. Recommended way to use presentation: • Use it as a slide show. • Decide on one structure and follow the sequence, example aorta. • Next attempt to see its relationship to other structures. • Study it multiple times until you are comfortable in identifying each structure. • When in doubt, follow the structure above and below and it will become evident.

  3. Exercises: First go through the entire sequence. • Follow axillary vein to superior vena cava entering right atrium. • Follow iliac veins to inferior vena cava entering right atrium. • Follow splenic vein to portal vein. • Follow aorta originating from LV to bifurcation to common iliac arteries. • Follow esophagus to rectum. • Follow trachea to RUL bronchus. • Follow SVC to RA to RV to main pulmonary artery and branches. • Focus on one structure and use the pg up/pg down option to follow it.

  4. At the level of Contrast is injected in the right antecubital vein.Follow the contrast in the next few slides. Trachea Contrast in axillary vein Thyroid cartilage

  5. Humerus Cervical spine Clavicle Scapula

  6. Pectoralis major AC joint Supraspinatus

  7. Thyroid Gland Thyroid gland First rib

  8. First rib

  9. Apex of lung

  10. Medial end of clavicle Rt common carotid artery Rt subclavian artery Left

  11. The subclavian vein joins the internal jugular vein to form the brachiocephalic vein behind the medial end of clavicle. Subclavian vein Right

  12. Left common carotid artery Left subclavian artery

  13. The brachiocephalic vein is also called the innominate vein.

  14. Sternum

  15. Because contrast was injected on the right side there is no visible contrast in left brachiocephalic vein. Leftbrachiocephalic vein Innominate vein

  16. Brachiocephalic artery Left

  17. A: Brachiocephalic artery B: Left common carotid artery C: Left subclavian artery A B C

  18. See how the left brachiocephalic vein is joining the right brachiocephalic vein to become the superior vena cava.

  19. Contrast in the right brachiocephalic vein has been diluted by blood from the left brachiocephalic vein as they combine to form the SVC.

  20. Arch of aorta Aortic arch SVC

  21. Mediastinal fat

  22. Scapula

  23. Ascending aorta Main pulmonary artery Descending aorta

  24. Contrast in SVC is diluted by blood from the azygous vein. Esophagus Azygous vein

  25. Left pulmonary artery Carina

  26. Right pulmonary artery Main pulmonary artery RUL bronchus Left pulmonary artery

  27. Left main bronchus

  28. SVC LUL division Intermediate bronchus

  29. Ascending aorta

  30. Rt atrium

  31. Rt ventricle

  32. Pulmonary vein Lt atrium

  33. A: Aortic root RV RA A LV LA

  34. Aortic valve

  35. Rt ventricle Lt ventricle

  36. Interventricular septum

  37. Osteophyte
