MAGNETIC-RESONANCE-IMAGING OF HUMAN BRAIN-FUNCTION - PRINCIPLES, PRACTICALITIES, AND POSSIBILITIES

This article presents a review of functional magnetic resonance (fMR) imaging. Included are four sections that address the principles, pract icalities, and potentials of fMR imaging. The current types of hemodyn amic contrast available with fMR imaging, including blood volume, perf usion, and oxygenation, are discussed. Technical issues of fMR imaging , including interpretability and sensitivity, are described, and sever al currently unresolved issues are addressed. Also reviewed are common ly used fMR imaging platforms and clinical and research applications.
