As an alternative to contrast-enhanced (CE) MRA, we developed an accelerated non-contrast MRA of thoracic aorta using a combination of T2-prepared and fat saturation preparations, b-SSFP readout, 3D radial stack of stars sampling with tiny golden angles, and compressed sensing. This NC-MRA was compared with standard ECG-gated CE-MRA in 8 patients. Normalized signal difference and aortic diameters were not significantly different between CE- and NC-MRA methods.
