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 | ||
aNote different n (total) for IE and MDD due to six not assessable values for IE
