Table 1 Imaging modalities’ repeatability and reproducibility

From: Scorer and modality agreement for the detection of intervertebral disc calcification in Dachshunds

Modality Repeatability (95% CI) Reproducibility (95% CI)
Radiography 95.4%b (92.4–97.3) 92.9%c (67.8–98.8)
CT 90.4%a (84.8–94.1) 89.4%c (62.8–97.7)
MRI 93.8%a,b (88.9–96.6) 86.4%c (60.4–96.4)
  1. Model estimates of the repeatability and reproducibility for intervertebral disc (IVD) calcification scoring by radiography, computed tomography (CT) and magnetic resonance imaging (MRI) (interpreted as positive if MRI Pfirrmann grade ≥3), with 95% confidence intervals reported in brackets. Within a column, different superscript letters indicate significant differences between modalities
