iPAT: Applications for fast and cardiovascular MR imaging

Parallel imaging is a new magnetic resonance imaging method based on the parallel use of more than one receiver coil to acquire image data with less phase-encoding steps than in conventional imaging. Advantages of parallel acquisitions techniques are acceleration of imaging, reduction of motion artifacts, and decrease of susceptibility sensitivity. In this article, the basic reconstruction techniques SMASH and SENSE are described, and clinical applications of parallel acquisition techniques are demonstrated for functional cardiac imaging, pulmonary angiography and perfusion imaging, renal angiography, and high-resolution larynx imaging.
