METHOD FOR INTENSIFYING MTC EFFECT OF MAGNETIC RESONANCE DIAGNOSTIC DEVICE AND ANGIOGRAPHY APPLYING THE SAME

摘要

PURPOSE: To provide a method for enhancing the MTC effect of a magnetic resonance diagnostic device and further intensifying a contrast and to provide angiography capable of further improving the contrast of blood with the brain and improving the capacity to depict blood vessels by using MTC pulses en hanced in the MTC effect. CONSTITUTION: The MTC effect of the magnetic resonance diagnostic device is enhanced by providing the respective pulses constituting the MTC pulses with time intervals therebetween and setting the impression intensity of the respective pulses so as to attain 90 deg., -180 deg. and 90 deg., by which the contrast of the tissues contg. the much bound water and tissues contg. the little bound water is intensified. The signal intensity of the brain contg. the much bound water is extremely lowered and the signal of the blood contg. the little bound water is relatively increased if these pulses are applied to the angiography using the MTC pulses. The angiography having the excellent depicting power is thus obtained.
