Magnetic resonance imaging (MRI) is an imaging diagnostic system using radio waves, a magnetic field, and a computer to visualize internal organs of the human body and obtain diagnostic information. An MRI displays images of the body in “slices” similar to that of a CT scan, but it is also able to reflect greater contrast between different types of body tissues.
MRI images are produced without the use of radiation and there are no known side or after-effects. The procedure is painless, noninvasive, and you won’t see or feel anything during the exam. A faint knocking sound will be heard, which is the imaging process in operation. In some instances, contrast agents, such as gadolinium, are used to enhance certain anatomical structures and increase the diagnostic accuracy of the images.
Magnetic resonance imaging is used for virtually all parts of the body and is one of the advanced imaging techniques utilized at Preferred Imaging. In addition to its use to view precise details of the head, neck, spine, muscles, joints, and bones, it is also used to image the chest, abdomen and pelvis. Frequently, the differentiation of abnormal (diseased) tissue from normal tissues is better with MRI than with other imaging modalities such as X-ray, CT, and ultrasound.
