Hint:An MRI is a medical imaging technique. It is used to form detailed images of anatomy. It uses powerful magnetic and radio frequencies despite X-rays as in CT scans. These radiations penetrate much deeper to organs and give a clearer picture.
Complete answer:MRI stands for Magnetic resonance imaging and it is one of the most important medical tools that are used in the diagnosis of many diseases. It was developed in the 1970s and it came out to be a versatile imaging technique. MRI uses strong magnetic fields and radio waves that generate the images of the organs. MRI functioning is based on the principle of Nuclear Magnetic Resonance. MRI is used extensively in Neuroimaging as it gives a wide view with more depth. Using MRI various detailed images of organs, bone, soft tissues, and other small internal body structures can be obtained.
CT scan uses X-rays which has various harmful ionizing radiation effects. MRI does not use X-rays which makes it superior to CT scans. It is used widely in hospitals for diagnosis and follow-up of the disease. There may be some risks associated with MRI scans but it is much safer than CT scans. Also, MRI gives a detailed and clear image of organs as compared to CT scan.
Note: Earlier MRI was named NMRI which stands for Nuclear Magnetic Resonance imaging. Later ‘Nuclear’ was removed to avoid negative associations. Now, MRI is not only a medical diagnostic tool but it is also used in various biomedical researches. Non-living objects can also be studied using MRI.
