| مستخلص: | Magnetic resonance imaging (MRI) is a new and innovative technique that affords anatomic images in multiple planes and that may provide information about tissue characterization. The first magnetic resonance image was published in 1973 by Paul Lauterbur, PhD. Since that time, major technological advances, together with increasing clinical and investigative interests in the method, have been accompanied by the development of equipment that is now clinically applicable to man, with potentially great benefits in assessing pathophysiological states.The magnetic resonance images are obtained by placing the patient or the area of interest within a powerful, highly uniform, static magnetic field. Magnetized protons (hydrogen nuclei) within the patient align like small magnets in this field. Radiofrequency pulses are then used to create an oscillating magnetic field perpendicular to the main field from which the nuclei absorb energy and move out of alignment with the static field in a state of excitation. |
