Non-Contrast Enhanced angiography of the renal arteries is an important technology for patients with chronic kidney disease. Existing techniques, like b-TRANCE, have long acquisition times, which makes them sensitive to motion artifacts. Respiratory triggering or navigation can be used to improve motion robustness. This however results in even longer scan times. Compressed SENSE is an effective way for accelerating 3D acquisitions and can be used to substantially reduce scan times. In this study, we report preliminary results of a breath hold and free breathing approaches for contrast-free renal angiography by combining b-TRANCE with compressed SENSE.
