Functional MR imaging (fMRI) belongs already longer than two decades between methods used for the investigation of the human brain but also for monitoring of functional changes related to pathological processes. This article shortly explains physical and physiological basis of fMRI methods and shows its advantages and limitations. Also, various types of fMRI data acquisition and evaluation are discussed including their benefits as well as restrictions. Using several examples, different approach to fMRI application is demonstrated beginning with traditional visualization of activated regions to more modern way of investigation of the brain network connectivity. This article is not a survey of published results in fMRI field but rather it should help to reader with orientation in entire issues concerning of fMRI including some new trends in this region.
