Magnetic resonance imaging (MRI) is a powerful imaging tool that is used to evaluate nearly every organ and tissue in the body. It is the imaging modality of choice for the evaluation of the brain, spine, muscles, bones, joints, ligaments, tendons, soft tissues, adrenal glands, and liver. It can create detailed images of blood vessels and provide invaluable assistance in diagnosing diseases of the uterus, ovaries, prostate, pancreas, kidneys, and even of the bowel. (See Clinical Applications).
And it does all of this without using ionizing radiation.
Instead, MRI uses magnetic fields and radio waves to create its images. All tissues in the body possess hydrogen protons; nearly every tissue in the body possesses varying combinations of water and fat. By aligning the hydrogen protons of the body’s water and fat to a strong magnetic field and then measuring how they respond to various radio waves, MR computers can create unparalleled detailed pictures of nearly every tissue.
Furthermore, after the injection of an intravenous paramagnetic contrast agent, MRI can show how blood flows to various tissues. This in turn can further characterize normal from abnormal tissues.At Tristan Radiology Specialists, we offer “open” MRI services at our West Shore facility in Camp Hill. Our open MRI is a 1.0 T Philips Panorama magnet which is open on the sides to help reduce patient anxiety and increase patient comfort. Despite its “open” design, it still provides excellent quality MR images similar to closed systems.
