[in a new window]
  		Fig. 1A —43-year-old woman with rheumatoid arthritis. Fat-suppressed T2-weighted MR image depicts large osseous lesion at proximal aspect of lunate (arrow). Other less hyperintense osseous abnormalities are present elsewhere in carpus.

[in a new window]
  		Fig. 1B —43-year-old woman with rheumatoid arthritis. Corresponding enhanced T1-weighted image similarly depicts large lesion in lunate (arrow). Mild synovitis is more clearly evident (arrowhead) on enhanced imaging.

[in a new window]
  		Fig. 1C —43-year-old woman with rheumatoid arthritis. Corresponding CT image depicts large erosion along proximal lunate. Palmar subluxation of carpus distorts axial anatomy in this case.

 

Figure 4

[in a new window]
  		Fig. 2A —74-year-old woman with rheumatoid arthritis. Fat-suppressed T2-weighted MR image only faintly depicts subcortical abnormality at dorsal aspect of lunate (arrow).

 

Figure 5

[in a new window]
  		Fig. 2B —74-year-old woman with rheumatoid arthritis. Corresponding enhanced T1-weighted image clearly depicts this lesion at dorsal lunate. Mild synovitis is also more clearly evident.

 

Figure 6
View larger version (79K):

[in a new window]
  		Fig. 2C —74-year-old woman with rheumatoid arthritis. Corresponding CT image depicts equivocal subcortical radiolucency in corresponding location (arrow), seen only in retrospect.

 

Figure 7
View larger version (125K):

[in a new window]
  		Fig. 3A —37-year-old woman with rheumatoid arthritis. Fat-suppressed T2-weighted coronal MRI shows prominent, ill-defined marrow signal abnormality, or edema pattern, in third metacarpal base (arrow).

 

Figure 8
View larger version (121K):

[in a new window]
  		Fig. 3B —37-year-old woman with rheumatoid arthritis. Corresponding percent enhancement image also shows this abnormality (arrow), although it is less prominent and more focal.

 

Figure 9
View larger version (80K):

[in a new window]
  		Fig. 3C —37-year-old woman with rheumatoid arthritis. Axial CT image shows equivocal subchondral radiolucency at dorsal aspect of third metacarpal base (arrow), seen only in retrospect.

 

Figure 10
View larger version (79K):

[in a new window]
  		Fig. 3D —37-year-old woman with rheumatoid arthritis. Adjacent and more distal CT image shows potential deepening of enthesis at ulnar aspect of third metacarpal base (arrow), which was not interpreted as erosion.
