Table 2. Details of scan orders of post-contrast T1WI sequences for all patients.

Scan orders	Patient number	Interval time between contrast injection and the beginning of each sequence acquisition
A—B—C	12	1 min—6 min 21 s—12 min 18 s
A—C—B	13	1 min—6 min 21 s—11 min 54 s
B—C—A	14	1 min—6 min 57 s—12 min 30 s
B—A—C	12	1 min—6 min 57 s—12 min 18 s
C—A—B	14	1 min—6 min 33 s—11 min 54 s
C—B—A	12	1 min—6 min 33 s—12 min 30 s

A represents post-contrast MPRAGE sequence; B represents post-contrast PETRA sequence; C represents post-contrast DANTE-SPACE sequence. T1WI, T1-weighted imaging; DANTE-SPACE, delay alternating with nutation for tailored excitation sampling perfection with application-optimized contrasts using different flip angle evolution; MPRAGE, magnetization-prepared rapid acquisition with gradient echo; PETRA, pointwise encoding time reduction with radial acquisition.
