Magnetic Resonance Imaging


The final goal of the study at hand is to gain insight to the question “How does an MRI (Magnetic Resonance Imaging) work?”

MRI is a technological tool used for generating three-dimensional comprehensive anatomical illustrations. This technology is usually employed for discovering diseases, determining diagnosis, and monitoring cure. It is founded on a state-of-the-art technology which stimulates and monitors the change towards the rotational axis of protons which are in the water that constitutes live tissues.

An MRI machine can be simply described as a very sizeable and strong magnet in which a patient lies and a radio wave is employed to transfer signals to the patient’s body and get them back. The signals which come back from the magnet are interpreted into images by a computer that is linked to the scanner. In effect, the image that is obtained through the MRI machine starts and ends within the computer. It manages the ultimate action of collecting the image, transferring it to gradient speakers and radio frequency (RF) receivers, switching them on and off to acquire the correct series of pulse to the magnet, forwarding the data via the RF receiver to an adaptor of data which computerizes the signal and finally sending to the computer again to create an image. In order to acquire an MRI image, a patient is positioned in a sizeable magnet and has to lay motionless throughout the course of imaging for preventing from blurring the image. Contrast agents, which usually holding the Gadolinium element, can be given to a patient through his/her vein prior to or during the MRI in order to heighten the velocity that the protons rearrange with the magnetic field at. When the protons straighten more rapidly, the image gets brighter. MRI scanners are found in various magnet field strengths, which are measured in teslas or “T”, often ranging between 0.5T and 3.0T. MRI scanners also vary in sizes, which include open and wide-bore.

In time, MRI has turned into a well-liked and commonly found tool of cross-sectional imaging modality. This has been intentional due to the fact that MRI has experienced a rapid course of development since its invention and the improvement of MRI technology still continues with highest pace.
