Abstract

Magnetic resonance imaging with parallel coils is commonly used as a method to speed up the acquisition by exploiting spatial encoding. Another, distinct acceleration method is spatio-temporal modeling with adaptive acquisition, which has been previously proposed for dynamic cardiac MRI with a single coil. We propose an optimal acquisition scheme for parallel dynamic MRI combining the two methods. It provides accelerations up to the product of the individual accelerations. The proposed scheme produces an artifact-free cine of the dynamic object, with high spatial and temporal resolution. Simulations demonstrate the method for cases where neither parallel imaging nor adaptive acquisition alone is feasible.
