Diagnosis Of Diseases

Magnetic resonance imaging is the newest of the imaging modalities available for the diagnosis of diseases of children. No ionizing radiation is used and most studies are performed without the administration of contrast material. FUNDAMENTALS OF MAGNETIC RESONANCE IMAGE FORMATION Physics The physics of magnetic resonance imaging is only accurately explained by complex mathematics, but analogy can serve as a rough guide. When placed in a strong magnetic field, atomic nuclei containing odd numbers of protons and neutrons align along the lines of magnetic force. The magnetic fields used are in the range of 6,000 to 15,000 G. (The earth's magnetic field measures 5 G.) Although many kinds of nuclei can be used, current magnetic resonance imaging systems image hydrogen nuclei.

Susceptibility Artefact

Metal implants produce susceptibility artefacts in magnetic resonance imaging. We have explored the effects of scaphoid screw characteristics and orientation on MR susceptibility artefact. Titanium alloy, smallness and longitudinal alignment with the z-axis of the main magnetic field reduce the size of the susceptibility artefact.
