It is being used to detect the presence of certain diseases. MRI scanner is one large cylinder-shaped tube surrounded by a circular magnet. Patient will be positioned on the moveable examination table. The computer workstation that processes the imaging information is located in a separate room from the scanner. MRI does not utilize ionizing radiation, instead it uses a powerful magnetic field and pulses of radio waves energy without causing any chemical changes in the tissues. MR scanner will capture the energy and create an image of the body structures scanned based on the information. The computer then processes the signals and generates a series of images, each of which shows a thin slice of the body. Parallel imaging is one of MR techniques to reduce scan time.
