Parallel imaging is successfully used in combination with hyperpolarized gas MRI. The accelerated techniques allow for shorter breath holds for lung imaging which is highly desirable when imaging patients with lung disease or children. We present a 32 channel receive coil in combination with a Helmholtz transmit coil for hyperpolarized xenon imaging at 3T. Coil performance is demonstrated with 2D and 3D ventilation images acquired with TrueFISP and 2D GRE multislice sequences on a healthy volunteer.
