Summary of imaging parameters for FLAIR and T1 post-contrast sequences.

Imaging Parameter	FLAIR	T1 post-contrast
Acquisition (n, %)	2D (193, 96.5%) 3D (5, 2.5%) N/A (2, 1%)	2D (32, 16%) 3D (166, 83%) N/A (2, 1%)
Median (range) echo time (msec)	92.0 (10.0 – 400.0)	3.1 (1.8 – 26.1)
Median (range) repetition time (msec)	9000.0 (1700.0 – 12000.0)	1900.0 (5.9 – 2619.8)
Median (range) slice thickness (mm)	5.0 (1.0 – 5.5)	1.0 (0.9 – 5.0)
Median (range) slice spacing (mm)	5.0 (0.0 – 7.5)	0.0 (0.0 – 7.0)

^*N/A = not available; range = minimum – maximum
