Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary goal, diagnostic quality of supine CE-MRI, will be evaluated by 4 radiologists. Each will compare the diagnostic quality with the prone CE-MRI in terms of supine is: better, equal or worse. The image quality of the supine scan will visually be judged on visibility of the lesion extent, in categories, excellent, reasonable, dubious, and impossible. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary parameter is the accuracy of deformable image registration between prone CE-MRI scans and supine non-CE-MRI scans. Registration accuracy will be assessed by defining a set of corresponding anatomical landmarks in both images before registration. After registration, the distance between corresponding anatomical landmarks defines the registration accuracy. The identification of landmarks will be performed by two radiologists. The first radiologist will define the landmarks on both the prone and the supine scan. The second radiologist will be provided with the landmarks of the other radiologist on the prone scan, and define the corresponding landmarks on the supine scan. An ANOVA method will be used to define registration accuracy, taking into account observer variation. | — |
