The Technology Behind the Images How MRI Works
The wonder inside that device is a triumph of physics. Unlike X-rays using radiation, MRI uses a strong magnetic field and radio waves. The magnet aligns protons in your body’s water molecules. Pulsed radio waves push them off alignment, and as they realign, they emit faint signals. A advanced computer picks up these signals and creates incredibly detailed 2D and 3D images. This enables radiologists to differentiate between soft tissues – like brain matter, ligaments, or tumours – with remarkable clarity, making it essential for modern, precise medicine and diagnosis.
