The association of the ultra-short time-to-echo disc sign (UDS) with disc degeneration on traditional T2-weighted and T1-rho magnetic resonance imaging (MRI).

Presence of UDS (Subject-Specific)
MRI Variables	No (n = 65, 60.2%) mean (range,SD)	Yes (n=43, 39.8%) mean (range,SD)	p-value
T2-weighted Disc Degeneration Score†	7.0 (2–10, 1.9)	8.5 (5–12, 1.7)	<0.001^*
T1-rho Value (ms)	70.8 (47.5–128.6, 15.8)	63.5 (43.3–122.4, 14.8)	0.022^*

Note, the analysis represents 108 subjects.

SD: standard deviation, m/s:

^†

Cumulative score that represents summated individual disc scores from L1/2 to L5/S1.

Denotes statistical significance (p<0.05)
