MRI Brain Protocol & Technique

Image
  MRI Brain Protocol & Technique What is MRI Magnetic resonance imaging   ( MRI ) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. In many cases,   MRI   gives different information about structures in the body than can be seen with an X-ray, ultrasound, or computed tomography (CT) scan. How it Work The human body is mostly water. Water molecules (H20) contain hydrogen nuclei (protons), which become aligned in a magnetic field. An   MRI   scanner applies a very strong magnetic field (about 0.2 to 3 tesla  or roughly a thousand times the strength of a typical fridge magnet), which aligns the proton "spins."   Before the imaging start, the hydrogen atom inside your body Are aligned in random Direction.   A Super conducting magnet creates a strong magnet field that aligns all the hydrogen protons in your body in same dire...
