Magnetic Resonance Imaging (MRI)
Magnetic resonance imaging (MRI) is a scanning procedure that uses strong magnets and radiofrequency pulses to generate signals from the body. These signals are detected by a radio antenna and processed by a computer to create images.
What is MRI?
An MRI (Magnetic Resonance Imaging) is a medical imaging technique that uses strong magnetic fields and radio waves to create detailed images of the inside of the body, particularly soft tissues like the brain, muscles, and organs.
How it works:
- Magnetic Field: The MRI machine generates a strong magnetic field, which aligns the protons in the body’s hydrogen atoms (mainly in water molecules).
- Radio Waves: Radiofrequency pulses are sent through the body, causing the protons to temporarily shift their alignment.
- Signal Detection: As the protons return to their original position, they release energy, which is detected by the MRI machine and used to create detailed images of internal structures.
MRI is non-invasive, does not use ionizing radiation, and is particularly useful for imaging soft tissues and diagnosing neurological, musculoskeletal, and cardiovascular conditions.
Limitations and Considerations:
- Metal Implants: MRI is not suitable for people with certain types of metal implants, such as pacemakers, metal stents, or some artificial joints, because the magnetic field can interfere with these devices. Special precautions are necessary for people with such implants.
- Claustrophobia: Some patients may experience anxiety or claustrophobia because of the enclosed nature of the MRI machine.
- Cost and Availability: MRI machines are expensive, and the procedure can sometimes be less readily available than other imaging methods, such as X-rays.
MRI scans require an appointment, as preparation is often necessary. This might include fasting for a period of time, or drinking water in the lead up to your appointment.
