Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): comparison between 3T and 7T on sensitivity and specificity;Timepoint(s) of evaluation of this end point: 1-2 weeks before total mesorectal excision. | — |
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Validate the results of Nano MRI (use of MRI in combination with ferumoxtran) with actual pathology in rectal cancer;Secondary Objective: compare 7 tesla and 3 tesla MRI for lymph node detection in locally advanced rectal cancer;Primary end point(s): Sensitivity and specificity of 7T MRI scans with Sinerem enhancement for lymph node metastasis detection. We will make a subdivision into small (<5mm) and large nodes(=5mm).;Timepoint(s) of evaluation of this end point: 1-2 weeks before total mesorectal excision. | — |
