Course Description

Join Dr. Anushri Parakh for a case-based approach to CT angiography of the lower extremities, covering the indications for CTA runoff cases, relevant vascular anatomy, imaging technique, and a systematic approach to interpretation. Through real-world cases, learn reporting strategies, recognize common pitfalls, and evaluate a range of pathologies, including peripheral arterial disease, traumatic vascular injury, and non-atherosclerotic vascular disorders.

Read alongside Dr. Parakh as she walks through her approach to interpreting cases like:

  • Atherosclerosis Inflow
  • Emboli
  • Stent Patency
  • Infection
  • Pseudoaneurysm
  • Hyperemia
  • Popliteal Entrapment Syndrome
  • …and more!
