影像资料
Imaging Data
△DWI：左侧脑桥梗死
△DWI：left pontine infarction
△头颅3D-TOF-MRA：基底动脉狭窄（橙箭）
△Cranial 3D-TOF-MRA: basilar artery stenosis (orange arrow)
△管壁高分辨MRI：基底动脉局部管壁偏心增厚（黄箭），其内信号不均匀（提示斑块）；PDWI（质子加权成像）抑脂序列可见临近管腔的条样等信号纤维冒；T1WI和T2WI于增厚管壁局部检测到小片状高信号，此高信号区域在PDWI抑脂序列呈低信号，提示脂肪组织
△ High resolution vessel wall MRI: an eccentric thickening of the vessel wall was detected in the basilar artery (yellow arrow), it had heterogeneous signal (atherosclerotic plaque); the proton density weighted image (PDWI) with fat supspanssion showed a strip-like plaque fiber cap with iso-signal intensity; a partial area of this plaque spansented with a hyper-signal intensity on T1WI andT2WI, but with a hypo-signal intensity on PDWI with fat supspanssion, which prompted that this area had the fat tissue.
