PURPOSE
Acute, isolated intracranial dissection (ICD) represents a rare and challenging cause of acute stroke. DSA is considered to be the gold standard imaging modality in patients with ICD. The role of novel, high-resolution (HR) compressed-sensing (CS) time-of-flight (TOF) MRA techniques in ICDs is unclear.
METHODS
A 22-year-old male patient with an isolated right ICA/MCA intracranial dissection underwent "conventional" 3-T TOF MRA, HR CS TOF MRA and also DSA including digital rotational angiography.
RESULTS
Unlike the "conventional" TOF MRA, HR CS TOF MRA provided comparable image quality to rotational angiography and a dissection membrane was clearly visible in both techniques.
CONCLUSION
In this single case study, we demonstrated the feasibility of a novel HR CS TOF in a case of an acute isolated intracranial ICA/MCA dissection, which needs to be validated in a larger case series.
目的
急性孤立性颅内夹层（ICD）是一种罕见且具有挑战性的急性脑卒中病因。DSA 被认为是 ICD 患者的金标准成像方式。新型高分辨率（HR）压缩感知（CS）时间飞跃（TOF）MRA 技术在 ICD 中的作用尚不清楚。
方法
一名 22 岁男性患者发生孤立性右侧颈内动脉/大脑中动脉颅内夹层，接受了“常规”3T TOF MRA、HR CS TOF MRA 以及包括数字旋转血管造影的 DSA 检查。
结果
与“常规”TOF MRA 不同，HR CS TOF MRA 提供了与旋转血管造影相当的图像质量，两种技术均清晰显示了夹层膜。
结论
在这项单病例研究中，我们展示了新型 HR CS TOF 在急性孤立性颅内颈内动脉/大脑中动脉夹层病例中的可行性，这需要在更大的病例系列中进行验证。
