Magnetic resonance imaging is one diagnostic test that is non-invasive in nature. A strong magnet and radiofrequency waves are utilized. Unlike XRAY and CT scan, there is no use of radiation. Doctors can diagnose tumours, strokes, and disc herniation.

You can search MRI near me on Google to find out, for example, a good MRI scan centre in Delhi.

How does it work?

About 80% of the human body is made up of water. Hence, we have millions of hydrogen atoms within us. These atoms align according to the magnetic field when placed within a magnetic field. Then the radio wave does the disruption of polarity. Now a sensor examines how long it takes the atoms to come back to the original arrangement. Then a computer is used to see the clear patterns that resemble an image.

Doctors even inject some dye into the bloodstream. As a result of which the images get better and clear. This dye contains basically gadolinium. It possesses magnetic properties that help MRI to produce the best results.

MRI enable doctors to view the body in a layered structure. For detecting abnormalities, a sliced view serves as a great option.

MRI shows

·  Detection of tumours in the brain, a brain injury trauma, abnormalities, multiple sclerosis, infection, stroke.

·  Arteries and veins MRI helps locate blood vessels blockages and several arteries and veins malformations or disease.

·  MRI is sensitive to cartilage and bone structure changes resulting from injury, disease, or ageing. Herniated discs, pinched nerves, spinal tumours, spinal cord compression, and fractures can be detected.

·  The transformations or abnormalities in bone structure and cartilage due to injury, ailment or age are ideally detected by the MRI of the spine.

Types of MRI.

·  Standard MRI: A long cylindrical machine is utilized. It has a tube at the narrow centre. The patient needs to lay down on a sliding bed that goes inside the tube. In this type of MRI, the entire body goes inside the narrow tube.

·  Short bone MRI: It is a shorter version of standard MRI. In this type of MRI, the length of the cylindrical machine is reduced to half of its original. When the head is scanned, the head gets covered inside the tube only. Similarly, the feet go inside when scanned, not the entire body.

·  Open MRI: The machine resembles a bagel sliced into two halves.

Conclusion

MRI is a diagnostic technique that uses a strong magnet, radio waves and a computer. Doctors obtain a clear image of the interior body. You can get the most precise and clear images at the best MRI scan centre in Delhi.
