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.

急性ICA / MCA夹层的情况下，高分辨率压缩传感飞行时间MRA。

目的急性，孤立性颅内解剖（ICD）代表急性中风的罕见且具有挑战性的原因。DSA被认为是ICD患者的黄金标准成像方式。目前尚不清楚新型，高分辨率（HR）压缩传感（CS）飞行时间（TOF）MRA技术在ICD中的作用。方法对一名22岁男性右ICA / MCA颅内分离的男性患者进行“常规” 3-T TOF MRA，HR CS TOF MRA以及包括数字旋转血管造影在内的DSA。结果与“常规” TOF MRA不同，HR CS TOF MRA提供了与旋转血管造影术相当的图像质量，并且在两种技术中均清晰可见解剖膜。结论在这个案例研究中，
