The purpose of this retrospective study was to demonstrate the MRI features of cerebral manifestations in patients with fat embolism syndromes in comparison with cerebral CT (CCT). Magnetic resonance imaging was performed according to standard protocols revealing multiple small non-confluent hyperintense intracerebral lesions larger than 2 mm on proton-density and T2-weighted images to various extents in three of four patients with clinically suspected cerebral fat embolism. Cerebral CT was negative in all patients. Our findings confirm that MRI can detect cerebral fat embolism with a higher sensitivity than CCT. Thus, MRI should be the first choice for imaging of cerebral fat embolism.
这项回顾性研究的目的是对比脑CT(CCT),展示脂肪栓塞综合征患者脑部表现的MRI特征。按照标准方案进行磁共振成像,在4例临床疑似脑脂肪栓塞患者中的3例,质子密度加权像和T2加权像上发现多个直径大于2mm的非融合性小的脑内高信号病变,程度各异。所有患者的脑CT均为阴性。我们的研究结果证实,MRI检测脑脂肪栓塞的敏感性高于CCT。因此,MRI应作为脑脂肪栓塞成像的首选。
