Utility of Hybrid Angiography-CT in Interventional Radiology: Case-Based Examples

Although cone-beam computed tomography (CT) is the predominant cross-sectional imaging modality used by interventional radiologists, advancements in hybrid angiography-CT technology have demonstrated a strong potential for increased utilization in the angiography suite. The benefits of increased workflow efficiency, decreased relative cost, multipurpose utility, and most importantly, improved patient care, may encourage institutions to accept the higher upfront cost of angiography-CT rooms for potential long-term benefits. Hybrid angiography-CT setups are less prone to motion and streak artifacts and may provide superior image quality compared with cone-beam CT. Although angiography-CT technology has been most frequently utilized for oncologic treatments, its use is being expanded across multiple applications. In this review, the authors illustrate 6 nonhepatic cases at 2 tertiary hospitals that each showcase how angiography-CT technology enabled an intervention.
