Objective: In order to optimize the image acquisition time in the T1 3D SPACE Sequence when using Gd contrast media, the Signal Intensity was studied by Gd Phantom experiment by contrast media concentration according to the difference between Partial Fourier and Average. Method: Eight phantoms(10, 8, 6, 4, 2, 0.9, 0.5, 0.1 mmol) were used to evaluate the difference in Signal Intensity according to the difference between Partial Fourier and Average in the T1 3D SPACE Sequence. Partial Fourier was applied to 6/8, 7/8, and 8/8 based on Average 2.0, and Average 1.5, 1.7, 1.9 and 2.0 were applied to Partial Fourier 8/8. Results: The phantom Signal intensity of 10 mm, 8 mmol, 6 mmol, 4 mmol contrast medium decreased with increasing Partial Fourier and Average parameters. In the correlation analysis results for each factor, Partial Fourier and Average showed a strong negative correlation in the Signal Intensity correlation. 2 mm, 0.9 mm, 0.5 mmol, 0.1 mm contrast agent phantom Signal intensity was measured. As the value of Partial Fourier and Average increased, Signal intensity increased. In the correlation analysis results for each factor, Partial Fourier and Average showed a strong positive correlation in Signal Intensity correlation. Conclusion: In order to set the optimal scan time in T1 3D SPACE Sequence and maximize the contrast effect, apply the experimental result showing the maximum Signal intensity at 0.5 mmol and simultaneously reduce Partial Fourier and Average. Significant increase in Signal intensity was confirmed.
