The criterion standard for assessing brain AVM obliteration postradiosurgery is DSA. To explore the value of susceptibility-weighted angiography, we followed 26 patients with brain AVMs treated by radiosurgery using susceptibility-weighted angiography and DSA. Studies were evaluated by 2 independent readers for residual nidi. Susceptibility-weighted angiography demonstrated good intermodality (κ = 0.71) and interobserver (κ = 0.64) agreement, and good sensitivity (85.7%) and specificity (85.7%). Susceptibility-weighted angiography is a useful radiation- and contrast material-free technique to follow-up brain AVM obliteration postradiosurgery.
评估脑动静脉畸形（AVM）放射手术后闭塞的标准是数字减影血管造影（DSA）。为了探讨磁敏感加权血管成像的价值，我们对 26 例接受放射外科治疗的脑 AVM 患者进行了磁敏感加权血管成像和 DSA 随访。由 2 名独立的读者评估残留病灶。磁敏感加权血管成像显示出良好的模态间（κ=0.71）和观察者间（κ=0.64）一致性，具有良好的敏感性（85.7%）和特异性（85.7%）。磁敏感加权血管成像作为一种无辐射和对比剂的技术，可用于随访放射手术后脑 AVM 的闭塞。
