Abstract
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 φfor 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.
