MRA则是一种MR血管造影方式,可很好地显示脑血管及其病变,因MR诊断技术的不断发展,MRA目前可显示中小血管病变,比如仿DSA技术,显示的血管效果基本能达到DSA标准,受到了临床的认可。但是,随着CTA技术的应用,证实在脑动脉瘤诊断中也有不错的价值,受到了临床的重视。
荷兰研究对比了7T与3T - MRA对未破裂颅内动脉瘤的评估。研究涉及患者数据收集、测量动脉瘤等内容。结果显示二者评估类似,7T - MRI系统成像可全面评估动脉瘤。了解这些有助于准确评估动脉瘤,避免不当治疗决定,快来深入探究7T与3T - MRA在这方面的差异吧。
An MRA test can show if there is a blockage in a blood vessel in your brain that could have caused a stroke. Is an MRA exam safe in children? Yes, MRAs are safe for children. But infants and younger children usually can’t lie still in the machine, so they would likely need some ...
