The proposed image reconstruction at acceleration rates up to 12X. Thin MIP images (TOP) reconstructed using our magnitude-subtraction CS algorithm with increasingly under-sampling rates demonstrate image quality that is comparable to the reference at rates up to 8X. At rates 10X–12X, blurring and signal loss is noted in the coronal MIP (top) and axial reformatted image (BOTTOM), which results in incomplete visualization of a few arteries (arrows).
