What is an MRI and how does it work In some ways, it's similar to an X-ray, yet the technology is vastly different? Medical Resonance Imaging is an abbreviation for Magnetic Resonance Imaging. When patients have been injured or appear to be suffering from major medical illnesses such as cancer or muscular/skeletal issues, MRI scans are used to acquire images from inside the body. Since the 1980s, these scans have been widely employed in western medicine, yet many people still don't understand how they function.

When a patient undergoes an MRI scan, radio waves and magnetic fields measured in gauss units and teslas are used to create images from within the patient's body. To be scanned, the patient is placed on a table that is sent into the centre of the magnet, which resembles a tube. Because so much of the human body is made up of water, which comprises hydrogen and oxygen molecules, an MRI scan may take those hydrogen molecules and use radio-frequency radiation to realign the nuclei of the atoms back to their normal position. Atoms emit their own radio waves, which are recorded as images, during this process.

MRI scans are used by radiologists to create two-dimensional images from within the body, with bodily tissues and bones appearing black and everything else appearing lighter. This enables clinicians to assess blood arteries, breasts, pelvic organs, and chest and abdominal organs, including the heart. It also enables doctors to diagnose and monitor serious medical conditions such as blood vessel blockages or enlargements, breast cancer and implants, certain heart problems, cysts and solid tumours in the kidneys and other parts of the urinary tract, causes of pelvic pain in women, liver and intestinal diseases, suspected uterine congenital abnormalities in women undergoing infertility evaluation, and tumours in the abdomen, chest, pelvis, and reproductive organs.

MRI technology has revolutionised how doctors examine and treat their patients. It's a sophisticated technology that requires extensive training,
