what is MRI scan?

Answer 1

Magnetic Resonance Imaging (MRI), formerly referred to as Magnetic Resonance Tomography (MRT) or Nuclear Magnetic Resonance (NMR), is a method used to visualize the inside of living organisms as well as to detect the composition of geological structures.

It is primarily used to demonstrate pathological or other physiological alterations of living tissues and is a commonly used form of medical imaging. MRI has also found many novel applications outside of the medical and biological fields such as rock permeability to hydrocarbons and certain non-destructive testing methods such as produce and timber quality characterization.

A Computed Tomography (CT) scanner uses ionizing radiation, X-rays, to acquire its images, making it a good tool for dense tissue (bone) exams. MRI, on the other hand, uses radio frequency signals and a magnet to acquire its images. MRI is best suited for soft (non-calcified) tissue exams

What is an MRI scan?

An MRI (or magnetic resonance imaging) scan is a radiology technique that uses magnetism, radio waves, and a computer to produce images of body structures. The MRI scanner is a tube surrounded by a giant circular magnet. The patient is placed on a moveable bed which is inserted into the magnet. The magnet creates a strong magnetic field which aligns the protons of hydrogen atoms, which are then exposed to a beam of radio waves. This spins the various protons of the body, and they produce a faint signal that is detected by the receiver portion of the MRI scanner. The receiver information is processed by a computer, and an image is then produced.

The receiver information is processed by a computer, and an image is produced. The image and resolution is quite detailed and can detect tiny changes of structures within the body.

Answer 4

MRI is a short form for Magnetic Resonance Imaging, a technique that provides a better 'picture' of an organ or structure than X-ray does.
