基底动脉夹层动脉瘤的磁共振血管壁成像表现

目的总结分析基底动脉夹层动脉瘤的MR血管壁成像表现特点。材料与方法 27例经临床证实的基底动脉夹层动脉瘤病例,对基底动脉夹层动脉瘤的磁共振血管壁成像表现特点进行总结分析。结果基底动脉夹层动脉瘤影像征象包括血管迂曲扩张、内膜征、双腔征、壁内血肿、长段不规则或丝线样狭窄、鼠尾状闭塞。结论对于基底动脉夹层动脉瘤患者,行基底动脉磁共振血管壁成像能够清晰显示血管迂曲扩张、内膜征、双腔征、壁内血肿、长段不规则或丝线样狭窄、鼠尾状闭塞异常,是基底动脉夹层动脉瘤的一种有效准确的检查方法。

Findings in magnetic resonance vessel wall imaging of basilar artery dissecting aneurysm

AbstractObjective:To evaluate the manifestations of basilar artery dissecting aneurysm on magnetic resonance vessel wall imaging.Materials and Methods:Twenty-seven cases of basilar artery dissecting aneurysm were examined by magnetic resonance vessel wall imaging.Results: Basilar artery dissecting aneurysm included vascular circuity expansion, intramural hematoma, intimal lfap sign, double lumen sign, long irregular or thread-like stenosis, rat tail-shaped occlusion.Conclusion:Vascular circuity expansion, intramural hematoma, intimal lfap sign, double lumen sign, long irregular or thread-like stenosis, rat tail-shaped occlusion can be identiifed on magnetic resonance vessel wall imaging in patients with basilar artery dissecting aneurysm. Magnetic resonance vessel wall imaging is a good examine method of basilar artery dissecting aneurysm.
