In order to increase the qualitative value of MRI and reduce the relative image acquisition time, the mutual
intersection of Partial Fourier and Average was conducted to evaluate image distortion and acquisition time
according to the effects of FID and Susceptibility Artifact in the T1 3D SPACE Sequence. As a result of analyzing
the Roundness (%) of the phantom for Gd contrast agent concentration, when the Partial Fourier 8/8 was
fixed, as the Average increased, the Roundness (%) increased (distortion decreased). When the Average 2.0 was
fixed, as the Partial Fourier was reduced, the Roundness (%) decreased (distortion increased). As a result of
Correlation analysis on Roundness (%), Partial Fourier and Average showed a high positive correlation. Experimental
results on image distortion and acquisition time when using the T1 3D SPACE sequence showed that
reducing the Partial Fourier than the Average reduced the image distortion and shortened the acquisition time.
