|Østergaard et al.  (wrist)||
Most radiographic erosions were evident 2 years prior on MRI.|
aThe PPV of MRI erosion predicting radiograpic erosion over the course of 5 years was estimated to be 52%.
The relative risk of developing radiographic erosion when MRI erosion is present is 4.1 after 5 years.
|Scheel et al.  (wrist)||
Forty-one percent of MRI erosions were seen on radiographs 7 years later.|
aThe estimated PPV of MRI erosion predicting radiographic erosion at 7 years is 50%.
aThe estimated relative risk of MRI erosion for future radiographic erosion at 7 years is 43.
|McQueen et al.  (wrist)||
This is a study of early rheumatoid arthritis with symptoms of 6 months or less.|
Statistical results of an MRI erosion in the wrist predicting future radiographic erosion in the wrist at 1 year were sensitivity of 83%, specificity of 70%, PPV of 58%, NPV of 91%, and odds ratio of 11.6.
Twelve new erosions over a 1-year period were seen in the dominant wrist of 42 patients.
