B-TFE序列对主动脉粥样硬化的诊断价值

Utility of B-TFE sequence in the diagnosis of aortal atherosclerosis

目的探讨平衡全稳态快速场回波(B-TFE)序列对主动脉粥样硬化的诊断价值。方法收集临床怀疑主动脉粥样硬化(或主动脉瘤、主动脉夹层)的并行B-TFE序列及3DCE-MRA扫描的37例患者,评估B-TFE序列的影像质量,诊断敏感性和特异性。结果37例影像质量合格率为95%～97%,诊断敏感性、特异性均为100%。结论B-TFE序列成像速度快,且诊断主动脉粥样硬化具有较高的价值。

Objective To investigate the utility of B - TFE sequence in the diagnosis of aortal atherosclerosis. Methods Thirty - seven patients with clinically suspected aortal atherosclerotic disease underwent MR scans with B - TFE sequence and 3D CE - MR angiography. The quality of the imaging, diagnostic sensitivity and specificity obtained from the both techniques were compared and calculated. Results The salisfactory rate of images in all patients was 95 % to 97 %. The sensitivity and specificity of the both techniques were 100 %. Conclusion During the diagnosis of aortal atherosclerosis, the imaging velocity of B - TFE sequence is faster so that it is very valuable.
