This chapter is open for public to get an idea about the content and set up of the e-module: Orthopedics MR-MRS / MSK Imaging. The different chapters in the e-module will be: 1. Weightbearing / Standing up-Positional / axial loaded MRI, 2. Kinematic and arthrograms, 3. Additional RF sequences – supporting techniques and IQ (parameters) in MSK, 4. DWI, DTI and DCE in MSK, 5. T1 and T2 mapping and quantification in MSK, 6. Fat and tissue suppression techniques, 7 MRS in MSK, 8. Miscroscopic imaging and at the end of course a Conclusion, Review and Future items. Questions (false-true and multiple choice) and statements are built in at the end of each chapter.

Weight-bearing / Standing Up / Positional MRI or Axial-Loaded MRI has been strong in the low field MR systems. Is it now becoming an issue in the higher MR field systems? Is it becoming a MUST to do stress-loading for several indications for the spine and the joints? Developments are continuing!

Kinematic devices for more joints should be developped and it is a field which can be extended preferable with MSK radiologists, orthopedic surgeon and physical therapist/bio-mechanist. Can we soon do kinematic dynamic / real-time imaging? And direct and indirect MR arthrograms will it be combined with kinematic Imaging?

Still a lot of work needs to be done in fine-tuning protocols for MSK: the Synthetic Imaging protocols and the UTE RF sequences and IQ stays a big issue so the basics, implementation of the RF sequences and the new k-space trajectories should be understand.

DWI, DTI and DCE was a long time mainly in the field of Neuro MR but thanks of the new techniques like Compressed Sensing, Hyper Band (SMS) we can get to an acceptable acquisition time and an higher resolution.

Everybody is talking about Quantification, T1 and T2 Mapping, in MRI. It has been integrated into the software releases incredibly quickly and has proved a great help in diagnosis and reporting. Although significantly automated, we still need to master and understand the basics and the post-processing tools.

The Fat Suppression Techniques are explained and MR images are included as tips and hints. But will the DIXON method be the only one used in the future? Other tissue suppression techniques, such as MTC, should not be forgotten and should be better understood.

Microscopic Imaging and High Resolution MRI in bone, cartilage, ligaments, tendons and muscles is getting an interesting field with help of new hardware RF coils and the new UTE RF sequence which makes unvisible tissues visible in MRI

¹H, ¹³C, ³¹P and ²³Na MR Spectroscopy combined with MRI is still relatively recent but promising in the field of cancer, sports medicine, joint replacement etc. and hopefully will get a feasible clinical diagnostic tool with help of more research.

There is still a lot to explore in the field of MR-MSK in all the items being discussed in all the different chapters: the conventional techniques still have some limitations in early detection of cartilage changes, bone and soft tissue as in arthritis and other muscle- and arthro-pathies.

In this chapter about MR in Sports Medicine in MSK the most typical injuries, classifications of muscle injuries, specific RF sequences, clincial applications, MRS and IVIM and imaging modalities are compared. The PDF file of this chapter has been available for a while for free but this chapter will be updated on a regular base.
