CT Angiography

• Computed tomographic angiography
  • Benefits
    • Useful to asses PAD anatomy and presence of significant stenoses
    • Useful to select patients who are candidates for endovascular or surgical revascularization
    • Helpful to provide associated soft tissue diagnostic information that may be associated with PAD presentation
    • Metal clips, stents, and metallic prostheses do not cause significant CTA artifacts
    • Scan times are significantly faster than for MRA
  • Limitations
    • Single-detector computed tomography lacks accuracy for detection of stenosis
    • Spatial resolution lower than digital subtraction angiography
    • Accuracy and effectiveness not as well determined as MRA
    • Asymmetrical opacification in legs may obscure arterial phase in some vessels
    • Requires iodinated contrast and ionizing radiation
    • Venous opacification can obscure arterial filling
