Magnetic Resonance Imaging (MRI)
Definition - What does Magnetic Resonance Imaging (MRI) mean?
Magnetic resonance imaging (MRI) is an imaging technique that uses radio frequency waves and a magnetic field to capture a visual representation of the interior of an object. Magnetic resonance imaging is often used to create images of the inside of the human body for diagnostic purposes. Magnetic resonance imaging may also be referred to as nuclear magnetic resonance imaging.
WorkplaceTesting explains Magnetic Resonance Imaging (MRI)
Magnetic resonance imaging (MRI) creates three-dimensional, real-time images that allow diagnosticians to view the body's internal organs and structures without the need for invasive surgery. MRIs may produce images that cannot be obtained using other methods such as x-rays, ultrasound, or computed tomography (CT) scans. Unlike x-rays that rely on radiation, an MRI scan uses radio frequency and magnetism to align the atoms within a patient's body in such a way that they send faint signals to the MRI machine. These radio wave created signals are then used to produce the MRI images. Contrast materials may sometimes be used to create clearer images during an MRI. Magnetic resonance imaging is used to detect and diagnose conditions, or to monitor the treatment or progression of a disease. Images created by MRI can be viewed directly via computer or saved and transmitted for later evaluation by the patient's physician.
