Key Points

The aim is to evaluate the use of T2 signal-intensity ratios for staging lumbar disc herniation and tracking nucleus pulposus dehydration.
Conducted a multicenter validation study with prospective follow-up.
Assessed T2 signal-intensity ratios to correlate with clinical outcomes.
Included evaluations of resorption following treatment.
Showed potential for T2 signal-intensity ratios to support reproducible LDH staging.
Clinical applicability remains limited without clear outcome correlation.
Found need for further studies to confirm these findings.

Implication

Prospective validation shows correlation of T2 signal ratios with lumbar disc herniation outcomes, indicating clinical relevance.

Abstract

Quantitative T2 SIRs track NP dehydration and may support reproducible LDH staging; however, clinical applicability is limited without outcome correlation. Prospective multicenter validation with follow-up, including resorption assessment, is needed.
