Magnetic resonance (MR) is used more and more frequently to diagnose changes in
the musculoskeletal system in the course of rheumatic diseases, at their initial
assessment, for treatment monitoring and for identification of complications. The
article presents the history of magnetic resonance imaging, the basic principles
underlying its operation as well as types of magnets, coils and MRI protocols
used in the diagnostic process of rheumatic diseases. It enumerates advantages
and disadvantages of individual MRI scanners. The principles of MRI coil
operation are explained, and the sequences used for MR image analysis are
described, particularly in terms of their application in rheumatology, including
T1-, T2-, PD-weighted, STIR/TIRM and contrast-enhanced T1-weighted images.
Furthermore, views on the need to use contrast agents to optimise diagnosis,
particularly in synovitis-like changes, are presented. Finally, methods for the
assessment of MR images are listed, including the semi-quantitative method by
RAMRIS and quantitative dynamic examination.
