This case report describes the usefulness of delay alternating with nutation for tailored excitation (DANTE)-prepared, contrast-enhanced magnetic resonance imaging (CE-MRI) for detecting the rupture site of an arteriovenous malformation (AVM). A ruptured intranidal aneurysm was confirmed histopathologically. Accurate non-invasive information about the possible rupture site of an AVM is critical for optimal treatment and evaluation. Vessel wall enhancement visualized by DANTE-prepared CE-MRI may be a useful tool for providing information about changes in inflammatory status and vulnerability to further developments.
本病例报告描述了延迟交替反转（DANTE）准备对比增强磁共振成像（CE-MRI）在检测动静脉畸形（AVM）破裂部位中的应用。破裂的瘤内动脉瘤通过组织病理学证实。准确的非侵入性信息对于 AVM 可能的破裂部位至关重要，这对于优化治疗和评估非常重要。DANTE 准备的 CE-MRI 显示的血管壁增强可能是提供关于炎症状态变化和对进一步发展的脆弱性信息的有用工具。
