PDF-One of the principle advantages of Magnetic Resonance Imaging MRI over other diagnos tic

Traditionally clinical imaging exploits the contrast due to differences in spin density spinlattice relaxation T and spinspin relaxation T between normal tissues and pathology However other contrast mechanisms such as susceptibility magnetization.

While MRI is considered to be a safe imaging technique, it is not without hazards. The magnet field will attract many ferromagnetic metals in an uncontrolled fashion and cause them to fly towards the magnets bore and turning them into high velocity projectiles. The bore of the magnet is where the fringe field is strongest, as all the lines of force are constricted and their relative strengths heightened. Various objects can be considered projectiles. test that helps doctors look for and treat many different medical problems. MRI scanners use a strong magnetic field and computers to create detailed pictures.

A contrast medium is a substance that is administered to the patient that is either more . radiopaque. or more radiolucent than the surrounding tissue. This allows assessment of the position, size, shape and internal architecture of the organ that was not apparent on the original radiograph. .
