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.
