Abstract
Established cone-beam CT angiography protocols exist for neurointerventional, hepatic, and prostatic artery applications, but no widely accepted acquisition framework addresses renal embolization, gastrointestinal hemorrhage, pulmonary vascular intervention, or below-the-knee peripheral disease. This narrative review searched PubMed/MEDLINE, EMBASE, and the Cochrane Library through May 2025 for acquisition parameters and contrast protocols in these territories. Six interdependent variables (injection rate, contrast concentration, volume, scan delay, catheter position, and hemodynamics) govern image quality and must be optimized jointly. Territory-specific parameters are synthesized, and radiation considerations are addressed, with emphasis on total procedural exposure and on whether cone-beam acquisitions replace, rather than simply add to, other angiographic acquisitions.Level of Evidence Level 5. Narrative review of published literature without formal quality assessment or meta-analysis.
期刊介绍：
CardioVascular and Interventional Radiology (CVIR) is the official journal of the Cardiovascular and Interventional Radiological Society of Europe, and is also the official organ of a number of additional distinguished national and international interventional radiological societies. CVIR publishes double blinded peer-reviewed original research work including clinical and laboratory investigations, technical notes, case reports, works in progress, and letters to the editor, as well as review articles, pictorial essays, editorials, and special invited submissions in the field of vascular and interventional radiology. Beside the communication of the latest research results in this field, it is also the aim of CVIR to support continuous medical education. Articles that are accepted for publication are done so with the understanding that they, or their substantive contents, have not been and will not be submitted to any other publication.
