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.

Acute lower limb ischaemia is a medical emergency that requires immediate diagnosis and management to avoid catastrophic consequences. As an alternative to open surgical procedures, endovascular intervention is a minimally invasive approach that can be effective in appropriately selected patients, with outcomes comparable to open surgery in contemporary series. The ongoing improvement and expansion of techniques and tools continue to refine clinical outcomes.

Non-sclerosant liquid embolic agents are safe and effective embolics that have been used in interventional radiology for more than 50 years, in both emergency and elective scenarios.
