The association of the ultra-short time-to-echo disc sign (UDS) with various imaging phenotypes on magnetic resonance imaging (MRI).

Presence of UDS (Subject-Specific)
MRI variables	No (n = 65, 60.2%) n (%)	Yes (n=43, 39.8%) n (%)	p-value
Disc degeneration†	47 (72.3%)	40 (93.0%)	0.01*
Multi-level disc degeneration	37 (56.9%)	36 (83.7%)	0.01*
Disc displacement‡	52 (80.0%)	40 (93.0%)	0.26
High-intensity zones	36 (55.3%)	27 (62.7%)	0.55
Endplate abnormalities	51 (78.4%)	33 (76.7%)	0.81
Modic changes	28 (43.0%)	29 (67.4%)	0.01*
Spondylolisthesis	2 (3.07%)	4 (9.3%)	0.21

Note, the analysis represents 108 subjects.

^†Subjects with a cumulative disc degeneration score from L1/2 to L5/S1 greater than 6.

^‡Subjects with disc bulge or extrusion
