Contrast agent-free MR angiography with SSFP sequences

摘要

In a method to generate an MR angiography image of an examination region of a subject without the use of contrast agent, a first MR image of the examination region is acquired with a first imaging sequence in which a gradient-induced phase development for unmoved and moved spins is essentially completely rephased at the end of a repetition interval TR, and a second MR image of the examination region is acquired with a second imaging sequence in which the gradient-induced phase development for unmoved spins is likewise essentially completely rephased at the end of the repetition interval TR and a rest phase &phgr;rest for moved spins remains at the end of the repetition interval TR. The second MR image is subtracted from the first MR image to generate the MR angiography image.
