MRI SCANNER
MRI scanner is a device used to scan the entire body mainly it is used scan the soft tissues, spinal injuries, vascular abnormalities etc.
Mechanism of working,
Since the body is composed largely of water, a magnetic resonance scan can isolate the molecules from other parts of the body to create an image. The mechanisms and workings of MRI machines rely on a large magnet to produce a electromagnetic field focused on the subject’s area of interest. The nuclei and protons of the water molecules then become aligned with the direction of the field. A radio frequency field is then projected for a brief period of time onto the same area, causing the protons to shift alignment. The scanner is able to pick up these changes, giving a technician the information necessary to determine the location of the molecules.

Uses of MRI scan
- Abnormalities of the brain and spinal cord
- Tumors, cysts, and other abnormalities in various parts of the body
- Injuries or abnormalities of the joints
