In order to assess the variability in interpreting lumbar CT-scans, two radiologists and two rheumatologists examined the same set of 40 CT-scans and evaluated the presence of primary abnormalities using pre-established criteria. Inter- and intraobserver concordance was assessed using kappa statistics. Interpretation of herniated nucleus pulposus appeared reliable in this study (interobserver and intraobserver kappa statistics approximately 0.7 and 0.9, respectively). Conversely, significant… CONTINUE READING
