Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Fatty infiltration of the supra- and infraspinatus in patients with rotator cuff tear, measured on ultrasound by using Computed Assisted Grey Scale Analysis with standard histogram function and Matlab. To reduce measurement variation we use both short- and long-axis images of the supra- and infraspinatus guided by anatomic landmarks. Using both axis we will evaluate grey scale intensities in two orthogonal directions of each rotator cuff muscle. This will give a representative impression of the amount of fat in each muscle on three different sagittal-oblique and coronal-oblique T1 images using modified Goutallier grading system. The ultrasound, magnetic resonance imaging and consultation will be conducted within three weeks. | — |
Secondary
| Measure | Time frame |
|---|---|
| - Muscle Echo Intensity (ipsilateral and contralateral rotator cuff) - Mean grey value ipsi- and contralateral (ultrasound) - Internal architecture rotator cuff, deltoid, trapezius (ipsi- & contralateral) - Mean modified Goutallier score and fat fraction (MRI) | — |
