Brief Summary
In summary, the investigators want to investigate whether UTE sequences are capable to replace imaging techniques involving ionizing radiation for bone imaging in the future. This would improve patient care greatly and might reduce medical imaging associated cancer risk drastically from an epidemiological standpoint. This field of research can be considered cutting-edge. The investigators determine this study promising to provide substantial generalizable knowledge and hope that this study results will improve patient care worldwide considerably.

Outcome Measures
Primary Outcomes (8)
Comparison of the accuracy of bone anatomy size dimensions measurements between regular MRI and UTE MRI
Outcome measure 1 will be to compare the bone anatomy as visible on the radiation-free UTE images with the reference standard (pre-existing radiographs or CT) during readouts performed by radiologists. The measurements for the primary endpoint will specifically be: \- size dimensions of the bony structures in three dimensions in millimeter
There is no baseline and follow-up examination for this study. The outcome measure will be assessed on the same day after the MRI examination is finished.
Comparison of the accuracy of cortical bone depiction between regular MRI and UTE MRI
Outcome measure 2 will be to compare the bone anatomy as visible on the radiation-free UTE images with the reference standard (pre-existing radiographs or CT) during readouts performed by radiologists. The measurements for the primary endpoint will specifically be \- clearly visibility of the cortical bone according to a scale 1-4 (1 = cortical bone not good visible; 4 = cortical bone good visible)
There is no baseline and follow-up examination for this study. The outcome measure will be assessed on the same day after the MRI examination is finished.
Comparison of the accuracy of cancellous bone depiction between regular MRI and UTE MRI
Outcome measure 3 will be to compare the bone anatomy as visible on the radiation-free UTE images with the reference standard (pre-existing radiographs or CT) during readouts performed by radiologists. The measurements for the primary endpoint will specifically be \- clearly visibility of the cancellous bone according to a scale 1-4 (1 = cancellous bone not good visible; 4 = cancellous bone good visible)
There is no baseline and follow-up examination for this study. The outcome measure will be assessed on the same day after the MRI examination is finished.
Comparison of the accuracy of calcification depiction between regular MRI and UTE MRI
Outcome measure 4 will be to compare the bone anatomy as visible on the radiation-free UTE images with the reference standard (pre-existing radiographs or CT) during readouts performed by radiologists. The measurements for the primary endpoint will specifically be \- clearly visibility of calcifications according to a scale 1-4 (1 = calcification not good visible; 4 = calcification good visible)
There is no baseline and follow-up examination for this study. The outcome measure will be assessed on the same day after the MRI examination is finished.
Comparison of the diagnostic performance for depiction of bony anatomy between regular MRI and UTE MRI
Outcome measure 5 will be to compare the bone anatomy as visible on the radiation-free UTE images with the reference standard (pre-existing radiographs or CT) during readouts performed by radiologists. The measurements for the primary endpoint will specifically be: \- diagnostic performance measurements for the depiction of bony anatomy (sensitivity, specificity, accuracy)
There is no baseline and follow-up examination for this study. The outcome measure will be assessed on the same day after the MRI examination is finished.
Comparison of the diagnostic confidence for depiction of bony anatomy between regular MRI and UTE MRI
Outcome measure 5 will be to compare the bone anatomy as visible on the radiation-free UTE images with the reference standard (pre-existing radiographs or CT) during readouts performed by radiologists. The measurements for the primary endpoint will specifically be: \- diagnostic confidence measurements for the depiction of bony anatomy (1-4, 1=anatomical bony structure certainly absent, 4= certainly present)
There is no baseline and follow-up examination for this study. The outcome measure will be assessed on the same day after the MRI examination is finished.
Comparison of the Signal-to-noise (SNR) measurements between regular MRI and UTE MRI
Outcome measure 6 will be to compare the bone anatomy as visible on the radiation-free UTE images with the reference standard (pre-existing radiographs or CT) during readouts performed by radiologists. The measurements for the primary endpoint will specifically be: \- Signal-to-noise (SNR)
There is no baseline and follow-up examination for this study. The outcome measure will be assessed on the same day after the MRI examination is finished.
Comparison of the Contrast-to-noise (CNR) measurements between regular MRI and UTE MRI
Outcome measure 7 will be to compare the bone anatomy as visible on the radiation-free UTE images with the reference standard (pre-existing radiographs or CT) during readouts performed by radiologists. The measurements for the primary endpoint will specifically be: \- Contrast-to-noise (CNR)
There is no baseline and follow-up examination for this study. The outcome measure will be assessed on the same day after the MRI examination is finished.
