T1-WEIGHTED IMAGING ACQUISITION METHOD FOR TISSUE SELECTIVELY WITH REMOVING THE SIGNAL OF FLOWING BLOOD

摘要

PURPOSE: A T1-weighted imaging acquisition method for tissue selectively with removing a signal of a flowing blood is provided to detect a brain metastasis from a T1-enhancement image by selectively improving the signal strength of a tumor. CONSTITUTION: A recovery pulse(70) comprising three short non-selective pulses is applied to an end portion of a refocusing pulse row(50). The recover pulse includes two pulses(71,72), and the last 90 ° pulse(73) which rotate at a negative longitudinal axis. The first two pluses are applied to the time interval between a second spin echo and the first spin echo. The last 90 ° pulse is applied to the time interval between the first two pluses and an ESP2/2.
