Vessel architecture imaging (VAI) MRI is a a technique that noninvasively measures parameters who describe the structural heterogeneity of brain microvasculature. To apply VAI in kidney disease respiratory motion artifacts need to be compensated for. In this study, a navigator along the inferior-superior direction was inserted as training data at the beginning of the measurement and interleaved during imaging acquisition. Our preliminary results suggest that respiratory motion can be corrected accurately.
