MRI

MRI is short for magnetic resonance imaging. An MRI is a technology that utilizes large magnets and radio waves to depict a high resolution image of the body's organs. The MRI machines are large, tube-like machines. When inside the machine, the magnetic field creates images when combined with  radio waves and the hydrogen atoms in the body. These images appear stacked, like a loaf of bread (Mayo Clinic Staff). An imaging technique related to MRI known as echo-planar imaging (EPI) was developed by Peter Mansfield and Paul Lauterbur in the late 1970s. To produce images of organs in the body, magnetic fields, electrical fields, and radio waves are used. MRI is very expensive, has low sensitivity, and time-consuming compared to other imaging devices. MRI may also need a probe with a bulk quantity. MRI can not detect abnormalities within the esophagus either. There is also no way to give real-time information. The physical portion of the image taking might create a suffocating environment for some people (Hussain et al.).
