Comparison of image quality of brain between conventional MR sequence and compilation sequence / 中国医学影像技术

ABSTRACT

Objective: To compare the image quality of brain of magnetic resonance image compilation (MAGiC) sequence and conventional MR sequence. Methods Ninety-six subjects underwent conventional MR sequences and MAGiC sequence scanning. The quality scores and SNR were compared between conventional MR sequence T1 FSE, T2 FSE, T1 Flair and T2 Flair images as well as MAGiC sequence reformated MAGiC T1, MAGiC T2, MAGiC T1 Flair and MAGiC T2 Flair images. Results There was no statistical difference of image quality score, artifact score, detection of lesions score between conventional sequences images and MAGiC sequence images (all P>0.05). SNR of MAGiC T1, MAGiC T2, MAGiC T1 Flair, MAGiC T2 Flair images were higher than that of corresponding conventional sequence images (all P<0.01). Conclusion: The quality of brain images captured with MAGiC and conventional sequences are similar, and SNR of MAGiC sequence images are higher than conventional sequence images.
