Magnetic resonance imaging (MRI) has a growing number of applications in the whole body area. Its role cannot be properly considered without comparing it to the diagnostic capabilities and availability of sonography and the high standard of newest-generation CT. MRI is an accepted diagnostic modality for diseases involving the pelvis and the musculoskeletal system. It is equal or superior to other modalities in examination of the neck, the cardiovascular system, the upper abdomen and the retroperitoneum.
