Neuroimaging means generating images of the brain noninvasively and then extracting useful information from the acquired images. It is a major part of radiological imaging and has been growing fast in Iran and around the world. In this presentation, we first review recent neuroimaging equipment developments and technological advancements. Then, we describe sample research projects in this exciting field. In particular, we discuss technical developments in Magnetic Resonance Imaging (MRI) that allow non-invasive evaluation of anatomy, physiology, and function of the brain. We will present samples of the image analysis methods developed for diagnosis and treatment evaluation of brain tumors, stroke, and epilepsy. These methods analyze anatomical MRI including proton density-weighted, T1-weighted, T2-weighted, and FLAIR images; physiological MRI including diffusion tensor images and functional images; and biochemical MRI including magnetic resonance spectroscopic images (MRSI). They also integrate information extracted from each of these methods to maximize accuracy of the results. We illustrate potentials of the proposed methods, discuss their limitations, and conclude with directions for future work.
