The department entitled "Department of Computed Tomography, Magnetic Resonance and Clinical Experimental Spectroscopy ZRIR" was established in the early 1990s in connection with the installation of the first 1.5T MR tomograph in Czechoslovakia.

The installation also included hardware for 31P MR spectroscopy and the first scientific studies were logically focused on this area. Later, 1H MR spectroscopy was added. As experience with MR imaging was gained, various software modifications were made to improve the MR examination and new imaging techniques were tested. Brain and heart imaging has become the major area of ​​research. At the end of the 1990s, it was necessary to expand the experimental activities of the MR department, so in cooperation with the Center for Cell Therapy and Tissue Replacements of the ASCR, an experimental 4.7T MR tomograph was installed at IKEM in 1999, which is still in operation today, and a molecular and cellular imaging group was formed.

Over the years (see the HISTORY section), the entire working group has grown, new staff and students have joined, and some of them have left. At present, researchers in individual fields are roughly divided into three working groups: 1) MR spectroscopy; 2) MR imaging; 3) molecular and cellular imaging. The studies carried out by all groups overlap and are not strictly separated, nor is the involvement of staff in individual projects. This is the principal advantage of the workplace. The character of the workplace, both in terms of age and professional profile, is currently optimal with a representation of both senior and junior scientists.
