The full forms of CT and MRI are:
- CT: Computed Tomography
- MRI: Magnetic Resonance Imaging
Computed Tomography (CT) Explained
Computed Tomography, often referred to as a CT scan, is an imaging technique that uses X-rays to create detailed cross-sectional images of the body. During a CT scan, the patient lies inside a donut-shaped machine while an X-ray tube rotates around them. Detectors measure the amount of X-rays that pass through the body, and a computer uses this information to reconstruct images of the internal organs, bones, soft tissues, and blood vessels.
Magnetic Resonance Imaging (MRI) Explained
Magnetic Resonance Imaging (MRI) is another advanced imaging technique that utilizes strong magnetic fields and radio waves to produce detailed images of the organs and structures within the body. An MRI scanner is a large, tube-shaped magnet. When a patient lies inside the MRI scanner, the magnetic field temporarily realigns water molecules in the body. Radio waves then cause these aligned molecules to produce signals, which are used to create cross-sectional MRI images. MRI is particularly useful for visualizing soft tissues, such as the brain, spinal cord, muscles, and ligaments.
