摘要

目的：探讨肝脏成像中磁共振BLADE技术的临床应用价值。方法：2012年5月—2013年5月期间共90例志愿者，采用数字抽取法随机分为三组，扫描序列分别是：A组：T2WI+FS+Trigger，K空间填充100%；B组：T2WI+FS+Trigger+BLADE，K空间填充100%；C组：T2WI+FS+Trigger+BLADE，K空间填充200%。对不同序列图像伪影评分及正常肝脏实质信噪比（SNR）进行统计学分析。结果：正常肝脏三组伪影评分有明显统计学差异（F=11.037，P<0.001），A组伪影统计学上多于B组及C组（P值分别为0.003及0.001 2）；正常肝脏三组SNR有明显统计学差异（F=11.037，P<0.001），A组统计学上明显低于B组及C组（P值分别为0.031及0.023）。结论：BLADE技术的应用，可减少肝脏MRI影像伪影，提高影像质量。

Abstract

Objective: To investigate the clinical value of BLADE sequence in MRI of liver. Methods: Ninty volunteers were enrolled during the period of May 2012 to May 2013. All subjects were randomly divided into three groups with digital extraction method: Group A, T2WI+FS+Trigger and K space with 100% filling. Group B: T2WI+FS+Trigger+BLADE and K space with 100% filling. Group C: T2WI+FS+Trigger+BLADE and K space with 200% filling. Image artifacts and signal to noise ratio(SNR) of normal liver parenchyma were statistically analyzed among different sequences. Results: Imaging artifacts scores of normal liver reached statistically significant difference among three groups(F=11.037, P<0.001). Imaging artifacts scores of normal liver in A group was statistically higher than group B and group C(P=0.003 and P=0.001 2 respectively); SNR of normal liver reached statistically significant difference among three groups(F=11.037, P<0.001). SNR of normal liver in A group was statistically lower than group B and group C(P=0.031 and P=0.023 respectively). Conclusion: BLADE technology can reduce artifacts in MRI of liver and improve its image quality.
