Angiography

Angiogram Views

• Angiogram views can be split into LAO, AP or RAO and then cranial or caudal
  • LAO or RAO refers to rotation around the vertical access
    • LAO refers camera positioned to the patient’s left (i.e. vertebral bodies will appear to the left of the image and the angiogram catheter will also be on the left side)
    • Oblong shape = RAO, ball shape = LAO
  • Cranial or caudal refers to rotation around the horizontal access
    • Cranial refers to looking down at the heart from the head end
