Recently, a new method using non-selective RF excitation was proposed for the scoutless acquisition of peripheral arteries. This method decreases the overall imaging time by using a non-selective RF pulses, but it does not take advantage of the speed benefits that could be obtained by the use of parallel imaging. By combining the benefits of both techniques a reduction in the acquisition time of abdominal angiography in the order of 30% can be achieved without significant reduction in image quality.
