Purpose
After reviewing this educational exhibit the audience will be able to: 1. Describe the pathophysiology/classification of peripheral arterial disease (PAD) and its clinical appearance.2. Understand common computed tomographic angiography (CTA)/magnetic resonance angiography (MRA) scan parameters and protocols for the evaluation of PAD.3. Be familiar with the basics of CTA/MRA interpretation, including the normal anatomy and common descriptive terms.4. Describe the typical imaging characteristics of PAD.5. Understand the role of CTA/MRA in guiding the interventional radiologist/vascular surgeon's decision for treatment of PAD.
Materials & Methods
An estimated 8 million Americans are affected by PAD with a prevalence of 14-29% in people older than 70 years.¹ CTA/MRA with lower extremity runoff has largely replaced conventional angiography in the initial evaluation and follow-up of PAD. A thorough understanding of the image acquisition process, anatomy, and appearance of PAD with its resultant impact on the treatment algorithm is crucial in CTA/MRA interpretation.
Results
This exhibit will illustrate the pathophysiology, clinical presentation, and classification schemes of PAD. Key scan parameters and technical considerations in protocoling CTA/MRA for PAD will be discussed. We will provide a brief review of normal anatomy and practical descriptive terms. Finally, the authors will present common CTA/MRA imaging patterns of PAD as well as salient information that should be conveyed to assist interventional radiologists and vascular surgeons in treatment planning.
Conclusions
The interventional radiologist maintains an important role as a diagnostician. As such, an understanding of and organized approach to the CTA/MRA is fundamental for assessment of peripheral arterial disease. Familiarity with classification schemes and treatment algorithms allow for concise reporting of pertinent findings and efficiency in patient care.
