Functional Magnetic resonance imaging.

Since the discovery of x-rays by Professor Roentgen in 1895, radiologists together with physicists and electrical engineers have been obsessively refining the techniques for detection of morphologic alterations in organ systems in health and disease. Recent advances in computed tomography (CT), and magnetic resonance imaging (MRI) have allowed for exquisite visualization of in vivo anatomy essentially in real time. Modern medicine is however, increasingly moving beyond gross anatomy and histopathology into the domain of molecular medicine. Radiology has tried to keep pace with this "molecular biological revolution". In recent years "Functional Imaging" has evolved as a new subspecialty of radiology. A variety of novel MRI sequences and nuclear medicine probes are now routinely used in clinical medicine, not to image diseased anatomy, rather to study in vivo tissue perfusion, metabolism and chemistry. This is a review article.
