Knowledge of upper extremity vascular geometry prior to dialysis access creation improves clinical outcome. Purpose of the present study was to compare a non-contrast enhanced (NCE) balanced TFE sequence with the current standard of reference, CE-MRA. In 10 healthy volunteers and 5 patients with ESRD we obtained both NCE-bTFE and CE-MRA images. Although CE-MRA was superior for arterial depiction NCE-bTFE yielded images of diagnostic quality in the vast majority of subjects. Furthermore, NCE-bTFE enabled visualization of significantly more venous segments compared compared to CE-MRA. bTFE proved to be an attractive alternative for pre-operative vascular mapping prior to vascular access creation.
