Agreement and differences of delineation between EPI- and HASTE-DWI determined pretreatmenta
| Agreement in % | Weighted κ (95% CI) | Differences of Means | Wilcoxon Signed Rank (P Value) | |
|---|---|---|---|---|
| HASTE-DWI observer 1 versus EPI-DWI observer 1 | 78% | 0.12 (−0.01–0.28) | 0.65 | <.0005 |
| HASTE-DWI observer 2 versus EPI-DWI observer 2 | 81% | 0.07 (−0.04–0.18) | 0.57 | <.0005 |
↵a The delineation of primary tumors and lymph nodes is determined by using a 3-point scale: score 1 = poor delineation, score 2 = moderate delineation, and score 3 = good delineation.
