ABSTRACT:
A method of producing a selective component enhanced image of an object. A uniform magnetic field is generated to magnetize the object and, once magnetized, a first preparatory pulse sequence which enhances the contrast of a first component of the object with respect to a second component of the object is generated. An RF pulse sequence is generated to produce transverse magnetization in the second component of the object. First, second, and third changing magnetic fields are generated, thereby producing a series of gradient echoes in response to the generated RF pulse sequence. A contrast enhanced image of the object may then be produced from the series of gradient echoes.
