摘要:
目的:探讨Radial 3D Time of Flight(TOF)序列在颈动脉磁共振血管成像中的应用。方法:选取行颈动脉常规3D TOF和Radial 3D TOF的36例患者的图像资料,采用配对样本t检验对比两个序列颈动脉的信噪比、对比噪声比,采用非参数配对Wilcoxon符号秩检验对比两个序列颈动脉血管的显示效果(主观评分)。结果:Radial 3D TOF的信噪比和对比噪声比均高于常规3D TOF(t=25.7、14.2, P值均小于0.05);血管的显示效果也优于常规3D TOF(z=-4.36, P<0.05)。结论:相比于常规3D TOF,Radial 3D TOF可以获得更好的颈动脉图像质量。
Abstract:
Abstract: Objective To evaluate the efficacy of Radial 3D time of flight (TOF) sequence for magnetic resonance angiography (MRA) of carotid artery. Methods The imaging data of 36 patients who underwent carotid artery MRA using conventional and Radial 3D TOF were collected. Paired-sample t-test was used to compare the signal-to-noise ratio and contrast-to-noise ratio of carotid artery MRA between two sequences, and Wilcoxon signed-rank test was used to compare the subjective score of carotid artery MRA between two sequences. Results Compared with conventional 3D TOF, Radial 3D TOF had higher signal-to-noise ratio, contrast-to-noise ratio (t=25.7, 14.2 P<0.05), and subjective scores (z=-4.36, P<0.05). Conclusion Radial 3D TOF is superior to conventional 3D TOF in displaying carotid artery.
