Know about MRI Devices Industry

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to create images of the body's anatomy and physiological processes. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to produce images of the organs in the body. MRI doesn't use X-rays or ionizing radiation, which is what sets it apart from CT and PET scans. MRI is a medical application of nuclear magnetic resonance (NMR) that can also be used for imaging in other NMR applications such as NMR spectroscopy.

While the dangers of ionizing radiation are now well understood in most medical contexts, an MRI can still be seen as a better choice than a CT scan. MRI is widely used in hospitals and clinics for medical diagnosis, staging and follow-up of diseases without exposing the body to radiation. An MRI can provide different information than a CT. Risks and discomfort can be associated with MRI scans. Compared to CT scans, MRI scans usually take longer and are louder. Usually the subject has to enter a narrow, confined tube. Additionally, people with some medical implants or other non-removable metal in the body may not be able to safely have an MRI scan.

MRI was originally called NMRI (magnetic resonance imaging), but "core" has been dropped to avoid negative associations. Certain atomic nuclei can absorb radio frequency energy when placed in an external magnetic field. The resulting developing spin polarization can induce an RF signal in a radio frequency coil and thereby be detected. In clinical and research MRI, hydrogen atoms are most commonly used to create a macroscopic polarization that is detected by antennas located near the subject being examined. Hydrogen atoms occur naturally in humans and other biological organisms, especially in water and fat.
