Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary study parameters are the expected sensitivity and specificity of MRDTI for diagnosing acute arm vein thrombosis. The sensitivity of MRDTI is determined by calculating to proportion of scans that are read as "positive for acute arm vein thrombosis" and the specificity is determined by calculating the proportion of scans that are read as "negative for acute arm vein thrombosis". | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary endpoints are 1) the optimization of the MRDTI scan sequences 2) the assessment of interobserver agreement between the reviewers | — |
