|Computed tomography angiography in renal artery disease|
CTA has significance in determining the existence and extent of RAD, as well as the underlying cause. It is a noninvasive method, carrying less risk for the patient than the invasive catheter angiography. While DSA is limited to luminal imaging, CTA allows us to also visualize the vessel walls, renal parenchymal morphology and surrounding tissues.
Compared to other noninvasive methods, such as ultrasound and magnetic resonance angiography, CTA offers better spatial and temporal resolution, implantable device compatibility and widespread availability.
