Abstract

BACKGROUND: PAOD is a clinical diagnosis, the clinical Rutherford classification is based on walking impairment and the extent of ischemic ulceration. However, the complete delineation of the peripheral vascular tree is mandatory for treatment decision and planning according to the TASC guidelines (1). For long time, digital subtraction angiography was considered the gold standard due to its high temporal and spatial resolution. However, DSA is an invasive procedure requiring intra-arterial application of contrast agents, with an associated risk of complications (2) and the exposure of both patients and observers to ionizing radiation. Thus, MR angiography and CT angiography have been developed over the last 20 years in an effort to replace DSA for diagnostic purposes and to limit it’s application to therapeutic procedures. LEARNING OBJECTIVES: This course will provide you with an overview of MRA and CTA of the peripheral arteries with special emphasis on their capabilities and limitations as well as most recent technical developments (3-5). The following issues will be covered: • Volume coverage • Spatial resolution • Acquisition time • Accurate and fast image post-processing • Patient safety • Cost efficiency Recent Publications 1.
