ABSTRACT:
Methods for improved MR imaging of an object by the use of back-to-back adiabatic RF pulse sequences. In one embodiment, a selective component suppressed MR image of the internal structure of an object is produced from a series of gradient echoes received in response to the generation of back-to-back opposing adiabatic half passage selective component suppressive RF pulses separated by 180 degrees in phase. In another embodiment, an enhanced MR image of the internal structure of an object is produced from a series of gradient echoes received in response to the generation of back-to-back opposing adiabatic half passage selective component suppressive RF pulses separated by 90 degrees in phase.
