Randomized Controlled Trial Clinical Trial
Interobserver and intraobserver variability in interpretation of lumbar disc abnormalities. A comparison of two nomenclatures.
A double-blind prospective study was used to measure interobserver and intraobserver variability when interpreting lumbar spine magnetic resonance imaging studies of disc abnormalities. ⋯ Experienced readers using standardized nomenclature showed moderate to substantial agreement with interpreting disc extension beyond the interspace on magnetic resonance imaging.
