Our Hitachi Altaire is a high field open MRI so it provides excellent image quality in a very open and non-claustrophobic environment. Our equipment was recently upgraded with enhanced software, to improve image quality.
What is an MRI?
Magnetic resonance imaging (MRI or MR) is one of the safest, most comfortable imaging techniques available. It combines a powerful magnet with an advanced computer system and radio waves to produce accurate, detailed pictures of organs and tissues in order to diagnose a variety of medical conditions.
Common uses of this procedure
Because MRI can give such clearnew-32 pictures of soft-tissue structures near and around bones, it is the most sensitive exam for spinal and joint problems. MRI is widely used to diagnose sports-related injuries, especially those affecting the knee, shoulder, hip, elbow, and wrist. The images allow the physician to see even very small tears and injuries to ligaments and muscles.
How does it work?
MRI is a unique imaging method because, unlike the usual radiographs (x-rays), radioisotope studies, and even CT scanning, it does not rely on ionizing radiation. Instead, radio waves are directed at protons, the nuclei of hydrogen atoms, in a strong magnetic field. The protons are first “excited” and then “relaxed,” emitting radio signals, which can be computer-processed to form an image. In the body, protons are most abundant in the hydrogen atoms of water — the “H” of H2O — so that an MRI image shows differences in the water content and distribution in various body tissues. Even different types of tissue within the same organ, such as the gray and white matter of the brain, can easily be distinguished. Typically an MRI exam consists of two to six imaging sequences, each lasting two to ten minutes. Each sequence has its own degree of contrast and shows a cross section of the body in one of several planes (right to left, front to back, upper to lower).
