- Figure 1.
Overview of previous studies on MRI scoring methods for the wrist with arthritis in both rheumatoid arthritis and juvenile idiopathic arthritis. MRI: magnetic resonance imaging; CMC: carpometacarpal joint; T2 fat-sat/STIR: fat-saturated/short-tau inversion recovery imaging; SI: signal intensity.
- Figure 2.
Area of bone depression (arrows) is visualized at baseline (a,b) and at followup (c,d) MRI scans of the wrist in a girl with JIA. At baseline both coronal T1-weighted (a) and axial T1-weighted fat-saturated MR images show an irregularity that would be scored as a bone erosion following the adult definitions. However, the followup MR images (c,d) fail to show any pathologic deterioration of the depression (i.e., synovial enhancement, enlargement of the lesion). MRI: magnetic resonance imaging; JIA: juvenile idiopathic arthritis.

MRI of the wrist of a girl with JIA shows an area of bone depression in the trapezium (arrows) similar to that of the patient in Figure 2 at baseline (a,b). But at followup, both the coronal T1-weighted (c) and axial T1-weighted fat-saturated images depict obvious synovial enhancement in the lesion, which is suggestive of a pathologic “bone erosion.” MRI: magnetic resonance imaging; JIA: juvenile idiopathic arthritis.

Tables
Preliminary statements on the MR imaging protocol for patients with JIA. The coil is more important than the field strength of the MRI
Voxel size should be discussed and defined
Fat-saturated T1-weighted images with the same scan parameters before and after contrast are warranted
MRI: magnetic resonance imaging; JIA: juvenile idiopathic arthritis.
