Abstract
Multiphase CTA offers several important advantages over the traditional single-phase CTA technique in acute ischemic stroke, including improved detection of large-vessel occlusion, improved characterization of collateral status, improved tolerance of patient motion and poor hemodynamics, and higher interrater reliability. These benefits are gleaned at little additional cost in terms of time, risk to the patient, and capital expense. Existing data suggest that there are important benefits to using multiphase CTA in lieu of single-phase CTA in the initial vessel assessment of patients with acute stroke.
摘要
多相 CTA 相较于传统单相 CTA 技术在急性缺血性脑卒中方面具有几个重要优势，包括提高了对大血管闭塞的检出率、改善了侧支循环状态的评估、提高了对患者运动和血流动力学不佳的耐受度，以及提高了组内可信度。这些获益在时间、患者风险和资本支出方面的额外成本很小。现有数据表明，在急性脑卒中患者的初始血管评估中，使用多相 CTA 替代单相 CTA 具有重要优势。
