Table 2 Comparison of fingers with pathologic FOI findings with the presence of current digital ulcers and/or pitting scars (DU/PS) in the same finger (SSc patients)
Initial enhancement (IE) | Maximum distal distribution (MDD) | |||
|---|---|---|---|---|
n (total)a | Strong signal proximal of fingertip, n (%) | n (total)a | Missing or insufficient signal in fingertip during entire examination, n (%) | |
Fingers with current DU/PS | 138 | 84 (60.9%) | 143 | 17 (11.9%) |
Fingers without current DU/PS | 476 | 124 (26.1%) | 477 | 9 (1.9%) |
p value (Fisher’s exact t test) | p < 0.0001 | p < 0.0001 | ||
