Exploiting sparsity to accelerate noncontrast MR angiography in the context of parallel imaging

Magnetic Resonance in Medicine, 04/24/2012

This demonstrates an inherent property of generalized autocalibrating partially parallel acquisition (GRAPPA) and does not require the use of compressed sensing. Application of this approach to highly accelerated data from healthy volunteers resulted in similar depiction of large arteries to that obtained with low acceleration and standard reconstruction. However, visualization of very small vessels and arterial branches was compromised.
