Computed Tomographic Angiography (CTA)

Computed Tomography Angiography (CTA) is a non-invasive 3D imaging study that provides reconstructive imaging of the blood flow through brain vasculature. Utilizing X-rays to visualize blood flow in the arteries, CTA displays anatomic detail of blood vessels, producing three-dimensional images of the vessels, which can be rotated in any direction and sliced to better examine individual arteries. And as the technique provides neuroradiologists with clear visualization of narrowed and clogged arteries that can cause stroke, they can detect coronary artery disease at an early stage when medication and lifestyle modification can reverse the course of the condition. CTA is also commonly used to:

  • Obtain precise information about lesions that involve the bone or skull base region,
  • Place of an invasive angiogram to determine whether a stent is serving its purpose, and
  • Image patients who are unable to undergo MR scanning due to pacemakers, metal implants or inability to fit in the MR scanner.
