Vessel size imaging at 3T requires sensitive mapping of the transverse gradient-echo and spin-echo relaxation rates. To realize hypercapnia-induced vessel size imaging at lower clinical field strength we demonstrate that the PROPELLER-EPI technique can be applied for this purpose. Results shown from our in-vivo study at 3T are then compared to a previous single-shot EPI study performed at 7T.
